CHAPTER VI.
MANURES AND FERTILIZERS
To a very small extent garden vegetables get their food from the air. The amount obtained in this way however, is so infinitesimal that from the practical standpoint it need not be considered at all. Practically speaking, your vegetables must get all their food from the garden soil.
This important garden fact may seem self-evident, but, if one may judge by their practice, amateur gardeners very frequently fail to realize it. The professional gardener must come to realize it for the simple reason that if he does not he will go out of business. Without an abundant supply of suitable food it is just as impossible to grow good vegetables as it would be to train a winning football team on a diet of sweet cider and angel cake. Without plenty of plant food, all the care, coddling, coaxing, cultivating, spraying and worrying you may give will avail little. The soil must be rich or the garden will be poor.
Plant food is of as many kinds, or, more accurately speaking, in as many forms, as is food for human beings. But the first distinction to make in plant foods is that between available and non- available foods—that is, between foods which it is possible for the plant to use, and those which must undergo a change of some sort before the plant can take them up, assimilate them, and turn them into a healthy growth of foliage, fruit or root. It is just as readily possible for a plant to starve in a soil abounding in plant food, if that food is not available, as it would be for you to go unnourished in the midst of soups and tender meats if the latter were frozen solid.
Plants take all their nourishment in the form of soups, and very weak ones at that. Plant food to be available must be soluble to the action of the feeding root tubes; and unless it is available it might, as far as the present benefiting of your garden is concerned, just as well not be there at all. Plants take up their food through innumerable and microscopic feeding rootlets, which possess the power of absorbing moisture, and furnishing it, distributed by the plant juices, or sap, to stem, branch, leaf, flower and fruit. There is one startling fact which may help to fix these things in your memory: it takes from 300 to 500 pounds of water to furnish food for the building of one pound of dry plant matter. You can see why plant food is not of much use unless it is available; and it is not available unless it is soluble.
THE THEORY OF MANURING
The food of plants consists of chemical elements, or rather, of numerous substances which contain these elements in greater or less degrees. There is not room here to go into the interesting science of this matter. It is evident, however, as we have already seen that the plants must get their food from the soil, that there are but two sources for such food: it must either be in the soil already, or we must put it there. The practice of adding plant food to the soil is what is called manuring.
The only three of the chemical elements mentioned which we need consider are: nitrogen, phosphoric acid, and potash. The average soil contains large amounts of all three, but they are for the most part in forms which are not available and, therefore, to that extent, may be at once dismissed from our consideration. (The non-available plant foods already in the soil may be released or made available to some extent by cultivation. See Chapter VII.) In practically every soil that has been cultivated and cropped, in long-settled districts, the amounts of nitrogen, phosphoric acid and potash which are immediately available will be too meager to produce a good crop of vegetables. It becomes absolutely necessary then, if one would have a really successful garden, no matter how small it is, to add plant foods to the soil abundantly. When you realize, (1) that the number of plant foods containing the three essential elements is almost unlimited, (2) that each contains them in different proportions and in differing degrees of availability, (3) that the amount of the available elements already in the soil varies greatly and is practically undeterminable, and (4) that different plants, and even different varieties of the same plant, use these elements in widely differing proportions; then you begin to understand what a complex matter this question of manuring is and why it is so much discussed and so little understood. What a labyrinth it offers for any writer—to say nothing of the reader—to go astray in!
I have tried to present this matter clearly. If I have succeeded it may have been only to make the reader hopelessly discouraged of ever getting at anything definite in the question of enriching the soil. In that case my advice would be that, for the time being, he forget all about it. Fortunately, in the question of manuring, a little knowledge is not often a dangerous thing. Fortunately, too, your plants do not insist that you solve the food problem for them. Set a full table and they will help themselves and take the right dishes. The only thing to worry about is that of the three important foods mentioned (nitrogen, phosphoric acid and potash) there will not be enough: for it has been proved that when any one of these is exhausted the plant practically stops growth; it will not continue to "fill up" on the other two. Of course there is such a thing as going to extremes and wasting plant foods, even if it does not, as a rule, hurt the plants. If, however, the fertilizers and manures described in the following sections are applied as directed, and as mentioned in Chapter VII., good results will be certain, provided the seed, cultivation and season are right.
VARIOUS MANURES
The terms "manure" and "fertilizer" are used somewhat ambiguously and interchangeably. Using the former term in a broad sense—as meaning any substance containing available plant food applied to the soil, we may say that manure is of two kinds: organic, such as stable manure, or decayed vegetable matter; and inorganic, such as potash salts, phosphatic rock and commercial mixed fertilizers. In a general way the term "fertilizer" applies to these inorganic manures, and I shall use it in this sense through the following text.
Between the organic manures, or "natural" manures as they are often called, and fertilizers there is a very important difference which should never be lost sight of. In theory, and as a chemical fact too, a bag of fertilizer may contain twice the available plant food of a ton of well rotted manure; but out of a hundred practical gardeners ninety- nine—and probably one more—would prefer the manure. There is a reason why—two reasons, even if not one of the hundred gardeners could give them to you. First, natural manures have a decided physical effect upon most soils (altogether aside from the plant food they contain); and second, plants seem to have a preference as to the form in which their food elements are served to them. Fertilizers, on the other hand, are valuable only for the plant food they contain, and sometimes have a bad effect upon the physical condition of the soil.
When it comes right down to the practical question of what to put on your garden patch to grow big crops, nothing has yet been discovered that is better than the old reliable stand-by—well rotted, thoroughly fined stable or barnyard manure. Heed those adjectives! We have already seen that plant food which is not available might as well be, for our immediate purposes, at the North Pole. The plant food in "green" or fresh manure is not available, and does not become so until it is released by the decay of the organic matters therein. Now the time possible for growing a crop of garden vegetables is limited; in many instances it is only sixty to ninety days. The plants want their food ready at once; there is no time to be lost waiting for manure to rot in the soil. That is a slow process—especially so in clayey or heavy soils. So on your garden use only manure that is well rotted and broken up. On the other hand, see that it has not "fire-fanged" or burned out, as horse manure, if piled by itself and left, is very sure to do. If you keep any animals of your own, see that the various sorts of manure —excepting poultry manure, which is so rich that it is a good plan to keep it for special purposes—are mixed together and kept in a compact, built-up square heap, not a loose pyramidal pile. Keep it under cover and where it cannot wash out. If you have a pig or so, your manure will be greatly improved by the rooting, treading and mixing they will give it. If not, the pile should be turned from bottom to top and outside in and rebuilt, treading down firmly in the process, every month or two— applying water, but not soaking, if it has dried out in the meantime. Such manure will be worth two or three times as much, for garden purposes, as that left to burn or remain in frozen lumps. If you have to buy all your manure, get that which has been properly kept; and if you are not familiar with the condition in which it should be, get a disinterested gardener or farmer to select it for you. When possible, it will pay you to procure manure several months before you want to use it and work it over as suggested above. In buying manure keep in mind not what animals made it, but what food was fed—that is the important thing. For instance, the manure from highly-fed livery horses may be, weight for weight, worth three to five times that from cattle wintered over on poor hay, straw and a few roots.
There are other organic manures which it is sometimes possible for one to procure, such as refuse brewery hops, fish scraps and sewage, but they are as a rule out of the reach of, or objectionable for, the purposes of the home gardener.
There are, however, numerous things constantly going to waste about the small place, which should be converted into manure. Fallen leaves, grass clippings, vegetable tops and roots, green weeds, garbage, house slops, dish water, chip dirt from the wood-pile, shavings—any thing that will rot away, should go into the compost heap. These should be saved, under cover if possible, in a compact heap and kept moist (never soaked) to help decomposition. To start the heap, gather up every available substance and make it into a pile with a few wheelbarrows full, or half a cartload, of fresh horse manure, treading the whole down firmly. Fermentation and decomposition will be quickly started. The heap should occasionally be forked over and restacked. Light dressings of lime, mixed in at such times, will aid thorough decomposition.
Wood ashes form another valuable manure which should be carefully saved. Beside the plant food contained, they have a most excellent effect upon the mechanical condition of almost every soil. Ashes should not be put in the compost heap, because there are special uses for them, such as dusting on squash or melon vines, or using on the onion bed, which makes it desirable to keep them separate. Wood ashes may frequently be bought for fifty cents a barrel, and at this price a few barrels for the home garden will be a good investment.
Coal ashes contain practically no available plant food, but are well worth saving to use on stiff soils, for paths, etc.
VALUE OF GREEN MANURING
Another source of organic manures, altogether too little appreciated, is what is termed "green manuring"—the plowing under of growing crops to enrich the land. Even in the home garden this system should be taken advantage of whenever possible. In farm practice, clover is the most valuable crop to use for this purpose, but on account of the length of time necessary to grow it, it is useful for the vegetable garden only when there is sufficient room to have clover growing on, say, one half- acre plot, while the garden occupies, for two years, another half-acre; and then changing the two about. This system will give an ideal garden soil, especially where it is necessary to rely for the most part upon chemical fertilizers.
There are, however, four crops valuable for green-manuring the garden, even where the same spot must be occupied year after year: rye, field corn, field peas (or cow peas in the south) and crimson clover. After the first of September, sow every foot of garden ground cleared of its last crop, with winter rye. Sow all ground cleared during August with crimson clover and buckwheat, and mulch the clover with rough manure after the buckwheat dies down. Sow field peas or corn on any spots that would otherwise remain unoccupied six weeks or more. All these are sown broadcast, on a freshly raked surface. Such a system will save a very large amount of plant food which otherwise would be lost, will convert unavailable plant food into available forms while you wait for the next crop, and add humus to the soil—concerning the importance of which see Chapter VII.
CHEMICAL FERTILIZERS
I am half tempted to omit entirely any discussion of chemical fertilizers: to give a list of them, tell how to apply them, and let the why and wherefore go. It is, however, such an important subject, and the home gardener will so frequently have to rely almost entirely upon their use, that probably it will be best to explain the subject as thoroughly as I can do it in very limited space. I shall try to give the theory of scientific chemical manuring in one paragraph.
We have already seen that the soil contains within itself some available plant food. We can determine by chemical analysis the exact amounts of the various plant foods—nitrogen, phosphoric acid, potash, etc.—which a crop of any vegetable will remove from the soil. The idea in scientific chemical manuring is to add to the available plant foods already in the soil just enough more to make the resulting amounts equal to the quantities of the various elements used by the crop grown. In other words:
)
Available plant food elements in (
the soil, plus > == Amounts of food elements
Available chemical food elements ( in matured crop
supplied in fertilizers )
That was the theory—a very pretty and profound one! The discoverers of it imagined that all agriculture would be revolutionized; all farm and garden practice reduced to an exact science; all older theories of husbandry and tillage thrown by the heels together upon the scrap heap of outworn things. Science was to solve at one fell swoop all the age- old problems of agriculture. And the whole thing was all right in every way but one—it didn't work. The unwelcome and obdurate fact remained that a certain number of pounds of nitrogen, phosphoric acid and potash—about thirty-three—in a ton of good manure would grow bigger crops than would the same number of pounds of the same elements in a bag of chemical fertilizer.
Nevertheless this theory, while it failed as the basis of an exact agricultural science, has been developed into an invaluable guide for using all manures, and especially concentrated chemical manures. And the above facts, if I have presented them clearly, will assist the home gardener in solving the fertilizer problems which he is sure to encounter.
VARIOUS FERTILIZERS
What are termed the raw materials from which the universally known "mixed fertilizers" are made up, are organic or inorganic substances which contain nitrogen, phosphoric acid or potash in fairly definite amounts.
Some of these can be used to advantage by themselves. Those practical for use by the home gardener, I mention. The special uses to which they are adapted will be mentioned in Part Two, under the vegetables for which they are valuable.
GROUND BONE is rich in phosphate and lasts a long time; what is called "raw bone" is the best "Bone dust" or "bone flour" is finely pulverized; it will produce quick results, but does not last as long as the coarser forms.
COTTON-SEED MEAL is one of the best nitrogenous fertilizers for garden crops. It is safer than nitrate of soda in the hands of the inexperienced gardener, and decays very quickly in the soil.
PERUVIAN GUANO, in the pure form, is now practically out of the market. Lower grades, less rich in nitrogen especially, are to be had; and also "fortified" guano, in which chemicals are added to increase the content of nitrogen. It is good for quick results.
NITRATE OF SODA, when properly handled, frequently produces wonderful results in the garden, particularly upon quick-growing crops. It is the richest in nitrogen of any chemical generally used, and a great stimulant to plant growth. When used alone it is safest to mix with an equal bulk of light dirt or some other filler. If applied pure, be sure to observe the following rules or you may burn your plants: (1) Pulverize all lumps; (2) see that none of it lodges upon the foliage; (3) never apply when there is moisture upon the plants; (4) apply in many small doses—say 10 to 20 pounds at a time for 50 x 100 feet of garden. It should be put on so sparingly as to be barely visible; but its presence will soon be denoted by the moist spot, looking like a big rain drop, which each particle of it makes in the dry soil. Nitrate of soda may also be used safely in solution, at the rate of 1 pound to 12 gallons of water. I describe its use thus at length because I consider it the most valuable single chemical which the gardener has at command.
MURIATE and SULPHATE OF POTASH are also used by themselves as sources of potash, but as a general thing it will be best to use them in combination with other chemicals as described under "Home Mixing."
LIME will be of benefit to most soils. It acts largely as an indirect fertilizer, helping to release other food elements already in the soil, but in non-available forms. It should be applied once in three to five years, at the rate of 75 to 100 bushels per acre, after plowing, and thoroughly harrowed in. Apply as long before planting as possible, or in the fall.
MIXED FERTILIZERS
Mixed fertilizers are of innumerable brands, and for sale everywhere. It is little use to pay attention to the claims made for them. Even where the analysis is guaranteed, the ordinary gardener has no way of knowing that the contents of his few bags are what they are labeled. The best you can do, however, is to buy on the basis of analysis, not of price per ton—usually the more you pay per bag, the cheaper you are really buying your actual plant food. Send to the Experiment Station in your State and ask for the last bulletin on fertilizer values. It will give a list of the brands sold throughout the State, the retail price per ton, and the actual value of plant foods contained in a ton. Then buy the brand in which you will apparently get the greatest value.
For garden crops the mixed fertilizer you use should contain (about):
)
Nitrogen, 4 per cent. ( Basic formula
Phosphoric acid, 8 per cent. > == for
Potash, 10 per cent. ( Garden crops
)
If applied alone, use at the rate of 1000 to 1500 pounds per acre. If with manure, less, in proportion to the amount of the latter used.
By "basic formula" (see above) is meant one which contains the plant foods in the proportion which all garden crops must have. Particular crops may need additional amounts of one or more of the three elements, in order to attain their maximum growth. Such extra feeding is usually supplied by top dressings, during the season of growth. The extra food beneficial to the different vegetables will be mentioned in the cultural directions in Part Two.
HOME MIXING
If you look over the Experiment Station report mentioned above, you will notice that what are called "home mixtures" almost invariably show a higher value compared to the cost than any regular brand. In some cases the difference is fifty per cent. This means that you can buy the raw chemicals and make up your own mixtures cheaper than you can buy mixed fertilizers. More than that, it means you will have purer mixtures. More than that, it means you will have on hand the materials for giving your crops the special feeding mentioned above. The idea widely prevails, thanks largely to the fertilizer companies, that home mixing cannot be practically done, especially upon a small scale. From both information and personal experience I know the contrary to be the case. With a tight floor or platform, a square-pointed shovel and a coarse wire screen, there is absolutely nothing impractical about it. The important thing is to see that all ingredients are evenly and thoroughly mixed. A scale for weighing will also be a convenience. Further information may be had from the firms which sell raw materials, or from your Experiment Station.
APPLYING MANURES
The matter of properly applying manure, even on the small garden, is also of importance. In amount, from fifteen to twenty-five cords, or 60 to 100 cartloads, will not be too much; although if fertilizers are used to help out, the manure may be decreased in proportion. If possible, take it from the heap in which it has been rotting, and spread evenly over the soil immediately before plowing. If actively fermenting, it will lose by being exposed to wind and sun. If green, or in cold weather, it may be spread and left until plowing is done. When plowing, it should be completely covered under, or it will give all kinds of trouble in sowing and cultivating.
Fertilizers should be applied, where used to supplement manure or in place of it, at from 500 to 1500 pounds per acre, according to grade and other conditions. It is sown on broadcast, after plowing, care being taken to get it evenly distributed. This may be assured by sowing half while going across the piece, and the other half while going lengthwise of it. When used as a starter, or for top dressings—as mentioned in connection with the basic formula—it may be put in the hill or row at time of planting, or applied on the surface and worked in during the growth of the plants. In either case, especially with highly concentrated chemicals, care must be taken to mix them thoroughly with the soil and to avoid burning the tender roots.
This chapter is longer than I wanted to make it, but the problem of how best to enrich the soil is the most difficult one in the whole business of gardening, and the degree of your success in growing vegetables will be measured pretty much by the extent to which you master it. You cannot do it at one reading. Re-read this chapter, and when you understand the several subjects mentioned, in the brief way which limited space made necessary, pursue them farther in one of the several comprehensive books on the subject. It will well repay all the time you spend upon it. Because, from necessity, there has been so much of theory mixed up with the practical in this chapter, I shall very briefly recapitulate the directions for just what to do, in order that the subject of manuring may be left upon the same practical basis governing the rest of the book.
To make your garden rich enough to grow big crops, buy the most thoroughly worked over and decomposed manure you can find. If it is from grain-fed animals, and if pigs have run on it, it will be better yet. If possible, buy enough to put on at the rate of about twenty cords to the acre; if not, supplement the manure, which should be plowed under, with 500 to 1500 pounds of high-grade mixed fertilizer (analyzing nitrogen four per cent., phosphoric acid eight per cent., potash ten per cent.)—the quantity in proportion to the amount of manure used, and spread on broadcast after plowing and thoroughly harrowed in. In addition to this general enrichment of the soil, suitable quantities of nitrate of soda, for nitrogen; bone dust (or acid phosphate), for phosphoric acid; and sulphate of potash, for potash, should be bought for later dressings, as suggested in cultural directions for the various crops.
If the instructions in the above paragraph are followed out you may rest assured that your vegetables will not want for plant food and that, if other conditions are favorable, you will have maximum crops.
CHAPTER VII
THE SOIL AND ITS PREPARATION
Having considered, as thoroughly as the limited space available permitted, the matter of plant foods, we must proceed to the equally important one of how properly to set the table, on or rather in, which they must be placed, before the plants can use them.
As was noted in the first part of the preceding chapter, most tillable soils contain the necessary plant food elements to a considerable extent, but only in a very limited degree in available forms. They are locked up in the soil larder, and only after undergoing physical and chemical changes may be taken up by the feeding roots of plants. They are unlocked only by the disintegration and decomposition of the soil particles, under the influence of cultivation—or mechanical breaking up—and the access of water, air and heat.
The great importance of the part the soil must play in every garden operation is therefore readily seen. In the first place, it is required to furnish all the plant food elements—some seven in number, beside the three, nitrogen, phosphoric acid and potash, already mentioned. In the second, it must hold the moisture in which these foods must be either dissolved or suspended before plant roots can take them up.
The soil is naturally classified in two ways: first, as to the amount of plant food contained; second, as to its mechanical condition—the relative proportions of sand, decomposed stone and clay, of which it is made up, and also the degree to which it has been broken up by cultivation.
The approximate amount of available plant food already contained in the soil can be determined satisfactorily only by experiment. As before stated, however, almost without exception they will need liberal manuring to produce good garden crops. I shall therefore not go further into the first classification of soils mentioned.
Of soils, according to their variation in mechanical texture, I shall mention only the three which the home gardener is likely to encounter. Rocks are the original basis of all soils, and according to the degree of fineness to which they have been reduced, through centuries of decomposition by air, moisture and frost, they are known as gravelly, sandy or clayey soils.
CLAY SOILS are stiff, wet, heavy and usually "cold." For garden purposes, until properly transformed, they hold too much water, are difficult to handle, and are "late." But even if there be no choice but a clay soil for the home garden, the gardener need not be discouraged. By proper treatment it may be brought into excellent condition for growing vegetables, and will produce some sorts, such as celery, better than any warm, light, "garden" soil. The first thing to do with the clay soil garden, is to have it thoroughly drained. For the small amount of ground usually required for a home garden, this will entail no great expense. Under ordinary conditions, a half-acre garden could be under-drained for from $25 to $50—probably nearer the first figure. The drains—round drain tile, with collars—should be placed at least three feet deep, and if they can be put four, it will be much better. The lines should be, for the former depth, twenty to thirty feet apart, according to character of the soil; if four feet deep, they will accomplish just as much if put thirty to fifty feet apart—so it pays to put them in deep. For small areas 2-1/2-inch land tile will do. The round style gives the best satisfaction and will prove cheapest in the end. The outlet should of course be at the lowest point of land, and all drains, main and laterals, should fall slightly, but without exception, toward this point. Before undertaking to put in the drains, even on a small area, it will pay well to read some good book on the subject, such as Draining for Profit and Draining for Health, by Waring.
But drain—if your land requires it. It will increase the productiveness of your garden at least 50 to 100 per cent.—and such an increase, as you can readily see, will pay a very handsome annual dividend on the cost of draining. Moreover, the draining system, if properly put in, will practically never need renewal.
On land that has a stiff or clay sub-soil, it will pay well to break this up—thus making it more possible for the water to soak down through the surface soil rapidly—by using the sub-soil plow. (See Chapter V.)
The third way to improve clay soils is by using coarse vegetable manures, large quantities of stable, manures, ashes, chips, sawdust, sand, or any similar materials, which will tend to break up and lighten the soil mechanically. Lime and land plaster are also valuable, as they cause chemical changes which tend to break up clayey soils.
The fourth thing to do in treating a garden of heavy soil is to plow, ridging up as much as possible, in the fall, thus leaving the soil exposed to the pulverizing influences of weather and frost. Usually it will not need replowing in the spring. If not plowed until the spring, care should be taken not to plow until it has dried out sufficiently to crumble from the plow, instead of making a wet, pasty furrow.
The owner of a clayey garden has one big consolation. It will not let his plant food go to waste. It will hold manures and fertilizers incorporated with it longer than any other soil.
SANDY SOIL is, as the term implies, composed largely of sand, and is the reverse of clay soil. So, also, with the treatment. It should be so handled as to be kept as compact as possible. The use of a heavy roller, as frequently as possible, will prove very beneficial. Sowing or planting should follow immediately after plowing, and fertilizers or manures should be applied only immediately before.
If clay soil is obtainable nearby, a small area of sandy soil, such as is required for the garden, can be made into excellent soil by the addition of the former, applied as you would manure. Plow the garden in the fall and spread the clay soil on evenly, harrowing in with a disc in the spring. The result will be as beneficial as that of an equal dressing of good manure—and will be permanent.
It is one of the valuable qualities of lime, and also of gypsum to even a greater extent, that while it helps a clay soil, it is equally valuable for a sandy one. The same is true of ashes and of the organic manures—especially of green manuring. Fertilizers, on sandy soils, where they will not long be retained, should be applied only immediately before planting, or as top and side dressing during growth.
Sandy soil in the garden will produce early and quick results, and is especially adapted to melons, cucumbers, beans and a number of the other garden vegetables.
GRAVELLY SOIL is generally less desirable than either of the others; it has the bad qualities of sandy soil and not the good ones of clay, besides being poorer in plant food. (Calcareous, or limestone pebble, soils are an exception, but they are not widely encountered.) They are not suited for garden work, as tillage harms rather than helps them.
THE IDEAL GARDEN SOIL is what is known as a "rich, sandy loam," at least eight inches deep; if it is eighteen it will be better. It contains the proper proportions of both sand and clay, and further has been put into the best of mechanical condition by good tilth.
That last word brings us to a new and very important matter. "In good tilth" is a condition of the soil difficult to describe, but a state that the gardener comes soon to recognize. Ground, continually and properly cultivated, comes soon to a degree of fineness and lightness at once recognizable. Rain is immediately absorbed by it, and does not stand upon the surface; it does not readily clog or pack down; it is crumbly and easily worked; and until your garden is brought to this condition you cannot attain the greatest success from your efforts. I emphasized "properly cultivated." That means that the soil must be kept well supplied with humus, or decomposed vegetable matter, either by the application of sufficient quantities of organic manures, or by green manuring, or by "resting under grass," which produces a similar result from the amount of roots and stubble with which the soil is filled when the sod is broken up. Only by this supply of humus can the garden be kept in that light, friable, spongy condition which is absolutely essential to luxuriant vegetable growth.
PREPARING THE SOIL
Unless your garden be a very small one indeed, it will pay to have it plowed rather than dug up by hand. If necessary, arrange the surrounding fence as suggested in the accompanying diagram, to make possible the use of a horse for plowing and harrowing. (As suggested in the chapter on Implements), if there is not room for a team, the one- horse plow, spring-tooth and spike-tooth cultivators, can do the work in very small spaces.
If however the breaking up of the garden must be done by hand, have it done deeply—down to the sub-soil, or as deep as the spading-fork will go. And have it done thoroughly, every spadeful turned completely and every inch dug. It is hard work, but it must not be slighted.
PLOWING
If the garden can be plowed in the fall, by all means have it done. If it is in sod, it must be done at that time if good results are to be secured the following season. In this latter case, plow a shallow furrow four to six inches deep and turning flat, as early as possible in the fall, turning under a coating of horse manure, or dressing of lime, and then going over it with a smoothing-harrow or the short blades of the Acme, to fill in all crevices. The object of the plowing is to get the sods rotted thoroughly before the following spring; then apply manure and plow deeply, six to twelve inches, according to the soil.
Where the old garden is to be plowed up, if there has not been time to get in one of the cover crops suggested elsewhere in this text, plow as late as possible, and in ridges. If the soil is light and sandy, fall plowing will not be advisable.
In beginning the spring work it is customary to put on the manure and plow but once. But the labor of double plowing will be well repaid, especially on a soil likely to suffer from drouth, if the ground be plowed once, deeply, before the manure is spread on, and then cross- plowed just sufficiently to turn the manure well under—say five or six inches. On stiff lands, and especially for root crops, it will pay if possible to have the sub-soil plow follow the regular plow. This is, of course, for thoroughly rotted and fined manure; if coarse, it had better be put under at one plowing, making the best of a handicap. If you have arranged to have your garden plowed "by the job," be on hand to see that no shirking is done, by taking furrows wider than the plow can turn completely; it is possible to "cut and cover" so that the surface of a piece will look well enough, when in reality it is little better than half plowed.
HARROWING
That is the first step toward the preparation of a successful garden out of the way. Next comes the harrowing; if the soil after plowing is at all stiff and lumpy, get a disc-harrow if you can; on clayey soils a "cut-a-way" (see Implements). On the average garden soil, however, the Acme will do the work of pulverizing in fine shape.
If, even after harrowing, the soil remains lumpy, have the man who is doing your work get a horse-roller somewhere, and go over the piece with that. The roller should be used also on very sandy and light soils, after the first harrowing (or after the plowing, if the land turns over mellow) to compact it. To follow the first harrowing (or the roller) use a smoothing-harrow, the Acme set shallow, or a "brush."
FINING.
This treatment will reduce to a minimum the labor of finally preparing the seed- or plant-bed with the iron rake (or, on large gardens, with the Meeker harrow). After the finishing touches, the soil should be left so even and smooth that you can with difficulty bring yourself to step on it. Get it "like a table"—and then you are ready to begin gardening.
Whatever implements are used, do not forget the great importance of making the soil thoroughly fine, not only at the surface, but as far as possible below Even under the necessity of repetition. I want to emphasize this again by stating the four chief benefits, of this thorough pulverization: First, it adds materially in making the plant foods in the soil available for use; secondly, it induces the growing plants to root deeply, and thus to a greater extent to escape the drying influence of the sun; thirdly, it enables the soil to absorb rain evenly, where it falls, which would otherwise either run off and be lost altogether, or collect in the lower parts of the garden; and last, and most important, it enables the soil to retain moisture thus stored, as in a subterranean storage tank, but where the plants can draw upon it, long after carelessly prepared and shallow soils are burning up in the long protracted drouths which we seem to be increasingly certain of getting during the late summer.
Prepare your garden deeply, thoroughly, carefully, in addition to making it rich, and you may then turn to those more interesting operations outlined in the succeeding sections, with the well founded assurance that your thought and labor will be rewarded by a garden so remarkably more successful than the average garden is, that all your extra pains-taking will be richly repaid.
Part Two—Vegetables
CHAPTER VIII.
STARTING THE PLANTS
This beautifully prepared garden spot—or rather the plant food in it— is to be transformed into good things for your table, through the ever wonderful agency of plant growth. The thread of life inhering in the tiniest seed, in the smallest plant, is the magic wand that may transmute the soil's dull metal into the gold of flower and fruit.
All the thought, care and expense described in the preceding chapters are but to get ready for the two things from which your garden is to spring, in ways so deeply hidden that centuries of the closest observation have failed to reveal their inner workings. Those two are seeds and plants. (The sticklers for technical exactness will here take exception, calling our attention to tubers, bulbs, corns and numerous other taverns where plant life puts up over night, between growth and growth, but for our present purpose we need not mind them.)
The plants which you put out in your garden will have been started under glass from seed, so that, indirectly, everything depends on the seed. Good seeds, and true, you must have if your garden is to attain that highest success which should be our aim. Seeds vary greatly—very much more so than the beginner has any conception of. There are three essentials; if seeds fail in any one of them, they will be rendered next to useless. First, they must be true; selected from good types of stock and true to name; then they must have been good, strong, plump seeds, full of life and gathered from healthy plants; and finally, they must be fresh. [Footnote: See table later this chapter] It is therefore of vital importance that you procure the best seeds that can be had, regardless of cost. Poor seeds are dear at any price; you cannot afford to accept them as a gift. It is, of course, impossible to give a rule by which to buy good seed, but the following suggestions will put you on the safe track. First, purchase only of some reliable mail-order house; do not be tempted, either by convenience or cheapness, to buy the gaily lithographed packets displayed in grocery and hardware stores at planting time—as a rule they are not reliable; and what you want for your good money is good seed, not cheap ink. Second, buy of seedsmen who make a point of growing and testing their own seed. Third, to begin with, buy from several houses and weed out to the one which proves, by actual results, to be the most reliable. Another good plan is to purchase seed of any particular variety from the firm that makes a leading specialty of it; in many cases these specialties have been introduced by these firms and they grow their own supplies of these seeds; they will also be surer of being true to name and type.
Good plants are, in proportion to the amounts used, just as important as good seed—and of course you cannot afford losing weeks of garden usefulness by growing entirely from seed sown out-doors. Beets, cabbage, cauliflower, lettuce, tomatoes, peppers, egg-plant, and for really efficient gardening, also onions, corn, melons, celery, lima beans, cucumbers, and squash, will all begin their joyous journey toward the gardener's table several weeks before they get into the garden at all. They will all be started under glass and have attained a good, thrifty, growing size before they are placed in the soil we have been so carefully preparing for them. It is next to impossible to describe a "good" vegetable plant, but he who gardens will come soon to distinguish between the healthy, short-jointed, deep-colored plant which is ready to take hold and grow, and the soft, flabby (or too succulent) drawn-up growth of plants which have been too much pampered, or dwarfed, weazened specimens which have been abused and starved; he will learn that a dozen of the former will yield more than fifty of the latter. Plants may be bought of the florist or market gardener. If so, they should be personally selected, some time ahead, and gotten some few days before needed for setting out, so that you may be sure to have them properly "hardened off," and in the right degree of moisture, for transplanting, as will be described later.
By far the more satisfactory way, however, is to grow them yourself. You can then be sure of having the best of plants in exactly the quantities and varieties you want. They will also be on hand when conditions are just right for setting them out.
For the ordinary garden, all the plants needed may be started successfully in hotbeds and cold-frames. The person who has had no experience with these has usually an exaggerated idea of their cost and of the skill required to manage them. The skill is not as much a matter of expert knowledge as of careful regular care, daily. Only a few minutes a day, for a few sash, but every day. The cost need be but little, especially if one is a bit handy with tools. The sash which serves for the cover, and is removable, is the important part of the structure. Sash may be had, ready glazed and painted, at from $2.50 to $3.50 each, and with care they will last ten or even twenty years, so you can see at once that not a very big increase in the yield of your garden will be required to pay interest on the investment. Or you can buy the sash unglazed, at a proportionately lower price, and put the glass in yourself, if you prefer to spend a little more time and less money. However, if you are not familiar with the work, and want only a few sash, I would advise purchasing the finished article. In size they are three feet by six. Frames upon which to put the sash covering may also be bought complete, but here there is a chance to save money by constructing your own frames—the materials required, being 2x4 in. lumber for posts, and inch-boards; or better, if you can easily procure them, plank 2 x 12 in.
So far as these materials go the hotbed and coldframe are alike. The difference is that while the coldframe depends for its warmth upon catching and holding the heat of the sun's rays, the hotbed is artificially heated by fermenting manure, or in rare instances, by hot water or steam pipes.
In constructing the hotbed there are two methods used; either by placing the frames on top of the manure heap or by putting the manure within the frames. The first method has the advantage of permitting the hotbed to be made upon frozen ground, when required in the spring. The latter, which is the better, must be built before the ground freezes, but is more economical of manure. The manure in either case should be that of grain-fed horses, and if a small amount of straw bedding, or leaves—not more, however, than one-third of the latter—be mixed among it, so much the better. Get this manure several days ahead of the time wanted for use and prepare by stacking in a compact, tramped-down heap. Turn it over after three or four days, and re-stack, being careful to put the former top and sides of the pile now on the inside.
Having now ready the heating apparatus and the superstructure of our miniature greenhouse, the building of it is a very simple matter. If the ground is frozen, spread the manure in a low, flat heap—nine or ten feet side, a foot and a half deep, and as long as the number of sash to be used demands—a cord of manure thus furnishing a bed for about three sash, not counting for the ends of the string or row. This heap should be well trodden down and upon it should be placed or built the box or frame upon which the sash are to rest. In using this method it will be more convenient to have the frame made up beforehand and ready to place upon the manure, as shown in one of the illustrations. This should be at least twelve inches high at the front and some half a foot higher at the back. Fill in with at least four inches—better six —of good garden soil containing plenty of humus, that it may allow water to soak through readily.
The other method is to construct the frames on the ground before severe freezing, and in this case the front should be at least twenty-four inches high, part of which—not more than half—may be below the ground level. The 2 x 12 in. planks, when used, are handled as follows: stakes are driven in to support the back plank some two or three inches above the ground,—which should, of course, be level. The front plank is sunk two or three inches into the ground and held upright by stakes on the outside, nailed on. Remove enough dirt from inside the frame to bank up the planks about halfway on the outside. When this banking has frozen to a depth of two or three inches, cover with rough manure or litter to keep frost from striking through. The manure for heating should be prepared as above and put in to the depth of a foot, trodden down, first removing four to six inches of soil to be put back on top of the manure,—a cord of the latter, in this case, serving seven sashes. The vegetable to be grown, and the season and climate, will determine the depth of manure required—it will be from one to two feet,—the latter depth seldom being necessary. It must not be overlooked that this manure, when spent for heating purposes, is still as good as ever to enrich the garden, so that the expense of putting it in and removing it from the frames is all that you can fairly charge up against your experiment with hotbeds, if you are interested to know whether they really pay.
The exposure for the hotbeds should be where the sun will strike most directly and where they will be sheltered from the north. Put up a fence of rough boards, five or six feet high, or place the frames south of some building.
The coldframe is constructed practically as in the hotbed, except that if manure is used at all it is for the purpose of enriching the soil where lettuce, radishes, cucumbers or other crops are to be grown to maturity in it.
If one can put up even a very small frame greenhouse, it will be a splendid investment both for profit and for pleasure. The cost is lower than is generally imagined, where one is content with a home-made structure. Look into it.
PREPARING THE SOIL
All this may seem like a lot of trouble to go to for such a small thing as a packet of seed. In reality it is not nearly so much trouble as it sounds, and then, too, this is for the first season only, a well built frame lasting for years—forever, if you want to take a little more time and make it of concrete instead of boards.
But now that the frame is made, how to use it is the next question.
The first consideration must be the soil. It should be rich, light, friable. There are some garden loams that will do well just as taken up, but as a rule better results will be obtained where the soil is made up specially as follows: rotted sods two parts, old rotted manure one part, and enough coarse sand added to make the mixture fine and crumbly, so that, even when moist, it will fall apart when pressed into a ball in the hand. Such soil is best prepared by cutting out sod, in the summer, where the grass is green and thick, indicating a rich soil. Along old fences or the roadside where the wash has settled will be good places to get limited quantities. Those should be cut with considerable soil and stacked, grassy sides together, in layers in a compost pile. If the season proves very dry, occasionally soak the heap through. In late fall put in the cellar, or wherever solid freezing will not take place, enough to serve for spring work under glass. The amount can readily be calculated; soil for three sash, four inches deep, for instance, would take eighteen feet or a pile three feet square and two feet high. The fine manure (and sand, if necessary) may be added in the fall or when using in the spring. Here again it may seem to the amateur that unnecessary pains are being taken. I can but repeat what has been suggested all through this book, that it will require but little more work to do the thing the best way as long as one is doing it at all, and the results will be not only better, but practically certain—and that is a tremendously important point about all gardening operations.
SOWING THE SEED
Having now our frames provided and our soil composed properly and good strong tested seed on hand, we are prepared to go about the business of growing our plants with a practical certainty of success—a much more comfortable feeling than if, because something or other had been but half done, we must anxiously await results and the chances of having the work we had put into the thing go, after all, for nothing.
The seed may be sown either directly in the soil or in "flats." Flats are made as follows: Get from your grocer a number of cracker boxes, with the tops. Saw the boxes lengthwise into sections, a few two inches deep and the rest three. One box will make four or five such sections, for two of which bottoms will be furnished by the bottom and top of the original box. Another box of the same size, knocked apart, will furnish six bottoms more to use for the sections cut from the middle of the box. The bottoms of all, if tight, should have, say, five three- quarter-inch holes bored in them to allow any surplus water to drain off from the soil. The shallow flats may be used for starting the seed and the three-inch ones for transplanting. Where sowing but a small quantity of each variety of seed, the flats will be found much more convenient than sowing directly in the soil—and in the case of their use, of course, the soil on top of the manure need be but two or three inches deep and not especially prepared.
Where the seed is to go directly into the frames, the soil described above is, of course, used. But when in flats, to be again transplanted, the soil for the first sowing will be better for having no manure in it, the idea being to get the hardest, stockiest growth possible. Soil for the flats in which the seeds are to be planted should be, if possible, one part sod, one part chip dirt or leaf mould, and one part sand.
The usual way of handling the seed flats is to fill each about one- third full of rough material—screenings, small cinders or something similar—and then fill the box with the prepared earth, which should first be finely sifted. This, after the seeds are sown, should be copiously watered—with a fine rose spray, or if one has not such, through a folded bag to prevent the washing of the soil.
Here is another way which I have used recently and, so far, with one hundred per cent, certainty of results. Last fall, when every bit of soil about my place was ash dry, and I had occasion to start immediately some seeds that were late in reaching me, my necessity mothered the following invention, an adaptation of the principle of sub-irrigation. To have filled the flats in the ordinary way would not have done, as it would have been impossible ever to wet the soil through without making a solid mud cake of it, in which seeds would have stood about as good a chance of doing anything as though not watered at all. I filled the flats one-third full of sphagnum moss, which was soaked, then to within half an inch of the top with soil, which was likewise soaked, and did not look particularly inviting. The flats were then filled level-full of the dust-dry soil, planted, and put in partial shade. Within half a day the surface soil had come to just the right degree of moisture, soaked up from below, and there was in a few days more a perfect stand of seedlings. I have used this method in starting all my seedlings this spring—some forty thousand, so far—only using soil screenings, mostly small pieces of decayed sod, in place of the moss and giving a very light watering in the surface to make it compact and to swell the seed at once. Two such flats are shown [ED., unable to recreate in typed format], just ready to transplant. The seedlings illustrated in the upper flat had received just two waterings since being planted.
Where several hundred or more plants of each variety are wanted, sow the seed broadcast as evenly as possible and fairly thick—one ounce of cabbage, for instance, to three to five 13 x 19 inch flats. If but a few dozen, or a hundred, are wanted, sow in rows two or three inches apart, being careful to label each correctly. Before sowing, the soil should be pressed firmly into the corners of the flats and leveled off perfectly smooth with a piece of board or shingle. Press the seed evenly into the soil with a flat piece of board, cover it lightly, one- eighth to one-quarter inch, with sifted soil, press down barely enough to make smooth, and water with a very fine spray, or through burlap.
For the next two days the flats can go on a pretty hot surface, if one is available, such as hot water or steam pipes, or top of a boiler, but if these are not convenient, directly into the frame, where the temperature should be kept as near as possible to that indicated in the following table.
In from two to twelve days, according to temperature and variety, the little seedlings will begin to appear. In case the soil has not been made quite friable enough, they will sometimes "raise the roof" instead of breaking through. If so, see that the surface is broken up at once, with the fingers and a careful watering, as otherwise many of the little plants may become bent and lanky in a very short time.
From now on until they are ready to transplant, a period of some three or four weeks, is the time when they will most readily be injured by neglect. There are things you will have to look out for, and your attention must be regular to the matters of temperature, ventilation and moisture.

The temperatures required by the different varieties will be indicated by the table above. It should be kept as nearly as possible within ten degrees lower and fifteen higher (in the sun) than given. If the nights are still cold, so that the mercury goes near zero, it will be necessary to provide mats or shutters (see illustrations) to cover the glass at night. Or, better still, for the few earliest frames, have double-glass sash, the dead-air space making further protection unnecessary.
VENTILATION: On all days when the temperature within the frame runs up to sixty to eighty degrees, according to variety, give air, either by tilting the sash up at the end or side, and holding in position with a notched stick; or, if the outside temperature permits, strip the glass off altogether.
WATERING: Keep a close watch upon the conditions of the soil, especially if you are using flats instead of planting directly in the soil. Wait until it is fairly dry—never until the plants begin to wilt, however—and then give a thorough soaking, all the soil will absorb. If at all possible do this only in the morning (up to eleven o'clock) on a bright sunny day. Plants in the seedling state are subject to "damping off"—a sudden disease of the stem tissue just at or below the soil, which either kills the seedlings outright, or renders them worthless. Some authorities claim that the degree of moisture or dampness has nothing to do with this trouble. I am not prepared to contradict them, but as far as my own experience goes I am satisfied that the drier the stems and leaves can be kept, so long as the soil is in good condition, the better. I consider this one of the advantages of the "sub-irrigation" method of preparing the seed flats, described above.
TRANSPLANTING: Under this care the little seedlings will come along rapidly. When the second true leaf is forming they will be ready for transplanting or "pricking off," as it is termed in garden parlance. If the plants are at all crowded in the boxes, this should be done just as soon as they are ready, as otherwise they will be injured by crowding and more likely to damp off.
Boxes similar to the seed-flats, but an inch deeper, are provided for transplanting. Fill these with soil as described for frames—sifted through a coarse screen (chicken-wire size) and mixed with one-third rotted manure. Or place an inch of manure, which must be so thoroughly rotted that most of the heat has left, in the bottom, and fill in with soil.
Find or construct a table or bench of convenient height, upon which to work. With a flat piece of stick or one of the types of transplanting forks lift from the seedling box a clump of seedlings, dirt and all, clear to the bottom. Hold this clump in one hand and with the other gently tear away the seedlings, one at a time, discarding all crooked or weak ones. Never attempt to pull the seedlings from the soil in the flats, as the little rootlets are very easily broken off. They should come away almost intact. Water your seed-flats the day previous to transplanting, so that the soil will be in just the right condition, neither wet enough to make the roots sticky nor dry enough to crumble away.
Take the little seedling by the stem between thumb and forefinger, and with a small round pointed stick or dibber, or with the forefinger of the other hand, make a hole to receive the roots and about half the length—more if the seedlings are lanky—of the stem. As the seedling drops into place, the tips of both thumbs and forefingers, by one quick, firm movement, compress the earth firmly both down on the roots and against the stem, so that the plant sticks up firmly and may not be readily pulled out. Of course there is a knack about it which cannot be put into words—I could have pricked off a hundred seedlings in the time I am spending in trying to describe the operation, but a little practice will make one reasonably efficient at it.
In my own work this spring, I have applied the "sub-irrigation" idea to this operation also. The manure placed in the bottom of the boxes is thoroughly watered and an inch of soil put in and watered also, and the box then filled and the plants pricked in. By preparing a number of flats at one time, but little additional work is required, and the results have convinced me that the extra trouble is well worth while. Of the early cabbage and cauliflower, not two plants in a thousand have dropped out.
Ordinarily about one hundred plants are put in a 13 x 19 inch flat, but if one has room and is growing only a few plants for home use, somewhat better plants may be had if fifty or seventy-five are put in. In either case keep the outside rows close to the edges of the flats, as they will have plenty of room anyway. When the flat is completed, jar the box slightly to level the surface, and give a thorough watering at once, being careful, however, to bend down the plants as little as possible. Set the flats close together on a level surface, and, if the weather is bright, shade from the sun during the middle of the day for two or three days.
From now on keep at the required temperature and water thoroughly on bright mornings as often as the soil in the flats gets on the dry side, as gardeners say—indicated by the whitening and crusting of the surface. Above all, give all the air possible while maintaining the necessary temperature. The quality of the plants will depend more upon this than anything else in the way of care. Whenever the temperature allows, strip off the sash and let the plants have the benefit of the rains. A good rain seems to do them more good than any watering.
Should your plants of cabbage, lettuce, beets or cauliflower by any chance get frozen, do not give them up for lost, for the chances are that the following simple treatment will pull them through: In the first place, shade them thoroughly from the sun; in the second, drench them with cold water, the coldest you can get—if you have to break the ice for it, so much the better. Try, however, to prevent its happening again, as they will be less able to resist subsequent injury.
In hot weather, where watering and ventilation are neglected, the plants will sometimes become infested with the green aphis, which under such conditions multiplies with almost incredible rapidity.
HARDENING OFF: For five days or a week before setting plants in the field they should be thoroughly hardened off. If they have been given plenty of air this treatment will mean little change for them—simply exposing them more each day, until for a few nights they are left entirely without protection. They will then be ready for setting out in the open, an operation which is described in the next chapter.
STARTING PLANTS OUTSIDE
Much of the above is applicable also to the starting of plants out-of- doors, for second and for succession crops, such as celery and late cabbage. Select for the outside seed-bed the most thoroughly pulverized spot to be found, enriched and lightened with fine manure. Mark off rows a foot apart, and to the necessary depth; sow the seed evenly; firm in if the soil is dry, cover lightly with the back of the rake and roll or smooth with the back of the spade, or of a hoe, along the drills. The seed, according to variety, will begin to push through in from four to twenty days. At all times keep the seed-bed clear of weeds; and keep the soil between the rows constantly cultivated. Not unless it is very dry will watering be necessary, but if it is required, give a thorough soaking toward evening.
As the cabbage, celery and similar plants come along it will add to their sturdiness and stockiness to shear off the tops—about half of the large leaves—once or twice after the plants have attained a height of about six inches.
If the precautions concerning seed and soil which I have given are heeded and the details of the work of planting, transplanting and care are carried out, planting time (April) will find the prospective gardener with a supply of good, stocky, healthy plants on hand, and impatient to get them into that carefully prepared garden spot. All of this work has been—or should have been—interesting, but that which follows in the next chapter is more so.
