he asparagus plant begins to produce seed when two years old. When fully developed the stalks are from five to six feet in hight, with numerous branches upon which are produced a profusion of bright scarlet berries, containing from three to six seeds each. It is not advisable, however, to harvest seed from plants less than four years old.

To save the seed the stalks are cut close to the ground as soon as the berries are ripe, which may be known by their changing color, from green to scarlet, and softening somewhat. The entire stalks are then cut off, tied in bundles, and hung up in a dry place safe from the attacks of birds, some kinds of which are very fond of this seed. After the berries are fully dried they are stripped off by hand, or thrashed upon a cloth or floor, and separated from the chaff. They are then soaked in water for a day or two to soften the skin and pulp of the berries, after which they are rubbed between the hands, or mashed with a wooden pounder, to break the outer shells. The separation of the pulp from the seed is accomplished by washing. When placed in water the seeds will settle with the pulp and the shells will readily pass away in pouring off the water. To clean the seeds thoroughly the washing has to be repeated three or four times. It is then spread on boards or trays to dry in the sun and wind. After the first day it should be removed from the sun, but exposed to the air in a dry loft, spread thin for ten days or more. When thoroughly dried the seed is stored in linen or paper bags until needed.

When cheapness of the seed is the main consideration such promiscuous harvesting may be permissible, but when only the best is desired careful selection and preparation becomes necessary. Even if the parent plants are of choice types, not all the seeds from them are equally good. The seed, for instance, which has been gathered from a stool which has flowered side by side with an inferior kind, and at the same time, may be worthless, because it has been fertilized badly. Then the last heads generally yield nothing but doubtful seed which seldom reproduces the proper type. The seeds which grow at the end of the shoots also, as well as those produced by the upper and lower extremities of the stem, have the same defect.

In order to insure the production of the very best asparagus seed a sufficient number of pistillate or seed-bearing plants, which produce the strongest and best spears, should be selected and marked so that they may be distinguished the following spring when the shoots appear. These clumps should be close together and near some staminate or male plants which have to be marked likewise, as without their presence fertile seed can not be produced. The number of the male to the female plants should be about one to four or five. The following spring all the sprouts of the selected male plants are allowed to grow without cutting any. On each hill of the female plants the two strongest and earliest stalks are allowed to grow, cutting the later appearing spears with the others for market or home use. Thus these early stalks of both male and female plants bloom together before any other stalks, and the blooms on the female plants will be fertilized with the pollen of the selected male plants. This last is of prime importance, for on proper fertilization depends the purity of the seed as well as the vigor of the resultant plant. Not all seed of even a good plant properly fertilized should be used for reproduction, as of the seeds gathered from any plant some will be better than others. Only the largest, plumpest, and best matured seeds should be used, for by saving these the most nearly typical plants of the sort will be most certainly produced. The selection of the best seed from typical plants is as essential to success as are good soil, thorough cultivation, and heavy manuring.

The best seeds are produced from the lower part of the stalk, hence it is well to top the plant after the seed is well set, taking off about ten inches, and to remove the berries from the upper branches, that all the strength may go to the full development of the more desirable berries. If, after this has been done, there is more than sufficient seed for the purpose desired, a second discrimination can be made between the seed of plants which produce numerous berries and those which are shy bearers, the latter being desirable, as this indicates a tendency in the plant to produce stalk rather than seed, and it is as a stalk producer that asparagus is valuable.

Harvesting, cleaning, and preserving the seed is, of course, to be done carefully; the separation of the heavy and the light seeds can be accomplished by means of water, while the larger can be selected from the resultant mass by the use of a properly meshed sieve.

In northern latitudes spring sowing is preferable to fall sowing. The ground of the seed-bed should be well drained and fairly retentive of moisture. As soon as the soil admits of working it should be well pulverized and enriched with decomposed manure. On a small scale a spading-fork is the best implement for preparing soil for nursery rows of asparagus plants.

Straight lines should be marked about fifteen inches apart and drills made about an inch deep when the sowing is done very early in the season, and one-half to one inch deeper when the sowing is done later. In these drills the seed should be dropped two or three inches apart. The covering may be made with a hoe, after which the soil should be well pressed down with the foot. As the seed is slow to germinate—in from four to six weeks, according to weather conditions—it is well to sow with it a few radish seeds, which will soon appear and mark the lines of the drills, so that cultivation may begin at once. Soaking the seed in luke-warm water for twenty-four hours before sowing will hasten its germination.

The cultivation of the young plants consists in keeping the soil about them light, and free from grass and weeds. Most of this work can be done with a garden cultivator, or a hoe and rake or prong hoe, but some hand weeding is generally necessary in addition. Strict attention to this will save a year in time, for if the seed-bed has been neglected, it will take two years to get the plants as large as they should be in one year if they had been properly cared for. In consequence of this very frequent neglect of proper cultivation of the seed-bed, it is a common impression that the plants must be two years old before transplanting. One pound of seed will produce about 10,000 plants, but as many of these will have to be thinned out and poor ones rejected, it is not safe to count upon more than one-half of this number of good plants. The number of plants required for an acre varies according to the manner of planting. If planted in rows three feet apart and two feet in the rows, it will require 7,260 plants per acre; if planted three by four, 3,630 per acre.

SOWING THE SEED WHERE THE PLANTS ARE TO REMAIN

Growing asparagus without transplanting is gradually finding many advocates among those who raise only the green article. It is not only a cheaper but in some respects a better method than the raising of the plants in a special seed-bed, from which they are transplanted after a year or two. "The plan is very simple," wrote Peter Henderson in American Agriculturist, "and can be followed by any one having even a slight knowledge of farming or gardening work. In the fall prepare the land by manuring, deep plowing, and harrowing, making it as level and smooth as possible for the reception of the seed. Strike out lines three feet apart and about two to three inches deep, in which sow the seed by hand or seed-drill, as is most convenient, using from five to seven pounds of seed to each acre. After sowing, and before covering, tread down the seed in the rows with the feet evenly; then draw the back of the rake lengthwise over the rows, after which roll the whole surface.

"As soon as the land is dry and fit to work in the spring, the young plants of asparagus will start through the ground, sufficient to define the rows. At once begin to cultivate with hand or horse cultivator, and stir the ground so as to destroy the embryo weeds, breaking the soil in the rows between the plants with the fingers or hand weeder for the same purpose. This must be repeated at intervals of two or three weeks during the summer, as the success of this plan is entirely dependent on keeping down the weeds, which, if allowed to grow, would soon smother the asparagus plants, that, for the first season of their growth, are weaker than most weeds. In two or three months after starting, the asparagus will have attained ten or twelve inches in hight, and it must now be thinned out, so that the plants stand nine inches apart in the rows. By fall they will be from two to three feet in hight and, if the directions for culture have been faithfully followed, strong and vigorous.

"When the stems die down (but not before) cut them off close to the ground, and cover the lines for five or six inches on each side with two or three inches of rough manure. The following spring renew cultivation, and keep down the weeds the second year exactly as was done during the first, and so on to the spring of the fourth year, when a crop will be produced that will well reward all the labor that has been expended. Sometimes, if the land is particularly suitable, a marketable crop may be secured the third year, but as a rule it will be better to wait until the fourth year before cutting much, as this would weaken the plants. To compensate for the loss of a year's time in thus growing asparagus from seed, cabbage, lettuce, onions, beets, spinach or similar crops that will be marketable before the asparagus has grown high enough to interfere with them, may be planted between the rows of asparagus the first year of its growth with but little injury to it."

GOOD CROPS TWO YEARS FROM SEED

In answer to the many inquiries as to how asparagus can be grown to weigh two and three-fourths pounds per bunch of twenty-six stalks from plants two years old from seed, as exhibited at a recent American Institute spring exhibition, George M. Hay, of Connecticut, writes in American Gardening as follows:

"Select a piece of ground where the soil is light, but of a good depth, and plow thoroughly. About the 1st of May mark off the rows three or four feet apart—for myself I prefer the latter distance as giving plenty of room for cultivation. Run a two-horse plow over the same furrow two or three times and you will have a depth of from fourteen to eighteen inches.

"Trenches having been all made, we come to the most important part—namely, manuring. In order to give the young plants a good start after germination we have to use liberal quantities of well-rotted stable manure, and in this the young plants make roots that in a short time are surprising. I use a one-horse load of manure to every seventy-five feet of drill, tramping it well down, and with a rake draw from each side of the trench soil to cover the manure to a depth of from two to three inches. The surface is raked level, and with the end of a rake or hoe a furrow one inch deep is drawn.

"We are now ready for the seed, which should have been soaked in tepid water for at least twenty-four hours. This will insure the immediate starting of the seed when the soil is moist and has not had a chance to dry out. If unsoaked seed is used and we have a dry spell for two or three weeks, the seed will be almost useless by the time it receives moisture enough to start.

"When the asparagus is two or three inches high thin out to one foot apart, being very careful not to disturb the plants left. A piece of a stick cut to the shape of a table-knife is an ideal tool for thinning out the young plants. It will be necessary to weed the rows by hand, while the plants are very small, for a distance of six inches on each side, as the cultivator, if run too close, will cover up the young plants. Keep the horse cultivator at work as often as possible to maintain moisture for the young roots.

"By fall you will be surprised to learn how far the young roots have traveled and the crowns prepared for next year's crop. Cover the rows with stable manure for the winter, and in spring give a dressing of one pound of nitrate of soda to one hundred feet of drill, and you will be well repaid for the extra labor and outlay by being able to cut asparagus of extra size in two years from the time of sowing the seed, doing away with the transplanting of two-year-old roots, and then waiting two more years before the first crop can be cut."

The principal objection which has been made against this system of not transplanting is that it does not admit of a careful choice of plants, as the plants must be kept in the places where sown, while in the transplanting method we need use only the choicest plants; then, if two or three seeds come up close together, it is very difficult to thin them out, and if left they will produce an inferior growth.

POT-GROWN ASPARAGUS PLANTS

In the tests made at the Missouri Experiment Station, Prof. J. C. Whitten found that it is much better to plant the seeds in six inches of rich, sandy soil in the greenhouse or hotbed, in February or early March, than to wait two or three months for outdoor planting. Professor Whitten advises to "sow liberally, for seven-eighths of the seedlings should be discarded. When the seedlings are three inches high, select those which have the thickest, fleshiest, and most numerous stems, and pot them. They vary more than almost any other vegetable. Many that appear large and vigorous will have broad, flat, twisted, or corrugated stems. Discard them. Beware, also, of those that put out leaves close to the soil. These will all make tough, stringy, undesirable plants. The best plants are those which are cylindrical, smooth, and free from ridges. They shoot up rapidly, and attain a hight of two inches before leaves are put out. They look much like smooth needles. This matter of selecting the best plants for potting, and subsequent planting out, is of the greatest importance in asparagus culture.

"These young plants should first be put in small pots and moved into larger ones as soon as they are well rooted. They may need to be shifted twice before they are planted out-of-doors, which should be done when danger of frost is over. Started in this way they continue to grow from the time they are planted out and reach very large size the first season. In the case of nursery-grown plants, where seeds are sown directly out-of-doors, the young seedlings start very slowly, are very tender during their early growth, and if the weather is unfavorable they hardly become well established before autumn."

Fig. 13 shows a one-year-old plant started in February in the greenhouse and transplanted to the field the first of May. Plants grown in this way reach as good size in one year as the nursery-grown plants usually do in three years.

VI

Equally important is a careful selection of the individual plants to be set out. A crown with four or five strong, well-developed buds is far better than one with a dozen or more of weak and sickly ones, as the latter will always produce thin and poor spears of poor quality. It is therefore highly to be recommended to select only plants with not over six buds and discard all others. The roots should be strong and of uniform thickness, succulent and not too fibrous. Dry or withered roots have to be cut off, and plants with many bruised or otherwise damaged roots should be rejected entirely. The best roots are the cheapest.

MALE AND FEMALE PLANTS

It has long been observed that all of the asparagus plants in a bed do not produce seeds, owing to the fact that the male and female flowers in asparagus are nearly always borne on separate plants. Seed bearing is an exhaustive process, and, as might be supposed, those plants that have produced seed have less vigor than those that have not. In order to determine the difference in vigor between the seed bearing and non-seed bearing plants, Prof. William J. Green, horticulturist of the Ohio Experiment Station, staked off fifty of each in a plantation of half an acre. When the cuttings were made the shoots taken from male and female plants were kept separate, and the weight of each recorded in Bulletin No. 9, Volume III., of the Ohio Station, as follows:

"The cuttings were made at regular intervals and in the ordinary manner, as for market purposes. The weight of shoots taken at each cutting is not given in the table, since the facts are quite as well shown by stating the aggregate weight for periods of ten days each. The division into periods is made for the purpose of showing comparative earliness. This could be shown in a more marked degree by taking the first and second cuttings alone, but they were too limited in quantity to admit of conclusions being drawn from them; hence they are included with the other cuttings in the same period.

PRODUCT FROM FIFTY PLANTS EACH, MALE AND FEMALE

"This shows a gain of the male over the female plants of seventy-six per cent. for the first period, and a fraction less than fifty per cent. for the whole season. Reversing the standard of comparison, it will be seen that the female plants fall below the male forty-three per cent. for the first period, and a little more than thirty-three per cent. in the total. In no case did the female plants produce equally with the male.

"If comparative earliness is determined by the date of first cutting alone, there is no difference between the male and female plants, since the first cutting was made on both at the same date; but taking quantity of product into consideration, which is the proper method, there is a decided difference, the gain of the male over the female plants being seventy-six, fifty-two, sixty-three, and thirty-one per cent. for the four periods respectively. The difference in yield between the two was greatest at first, and diminished toward the last, which practically amounts to the same thing as the male being earlier than the female. There is a still further difference between the two in quality of product, the shoots of the female plant being smaller and inferior to those of the male.

"It is not safe to draw conclusions from such limited observations as these, further, at least, than to accept them as representing the truth approximately. Allowing a wide margin for possible error, there would still seem to be sufficient difference in productive capacity between the male and female plants to justify the selection of the former and rejection of the latter when a new plantation is to be started. If the figures given in the table are taken as a basis, the gain in the crop, if the male plants alone were used, would each season pay for all the plants rejected, and leave a handsome margin at the end of the term of years when an asparagus bed has served its period of usefulness. Male plants can be secured by division of old plants, or by selecting those that bear no seed, after they have attained the age of two years."

In summing up the results of this experiment, Professor Green states that male asparagus plants are about fifty per cent. more productive than female plants, and the shoots being larger have a greater market value.

The question of what soil to use is, as a rule, already settled; we have to use the soil we have. Any good garden soil is suitable for asparagus, and if it is not in the most favorable condition, under existing circumstances, it can easily be made so. The soil should be free from roots, stones, or any material that will not readily disintegrate, or that will interfere with the growth of the spears, and with the knife in cutting. Fruit or other trees, or high shrubs, must not be allowed in the asparagus bed, because of the shade they throw over the beds, and because their roots make heavy drafts upon the soil. Nor should high trees, hedges, hills, or buildings be so near as to shade the beds, because all the sunshine obtainable is needed to bring the spears quickly to the surface. Whenever practicable the asparagus bed should be protected from cold winds, and so slope that the full benefit of the sunshine will be obtained during the whole day. Brinckmeier, in his "Braunschweiger Spargelbuch," gives the following three rules for guidance in selecting a location for asparagus beds:

"1. One should choose, in reference to ground characteristics, open, free-lying land, protected to the north and east [which, for American conditions, should be north and west], of gradual slope, free from trees or shrubbery.

"2. The field should be exposed to the rays of the sun all day long; therefore, a southern exposure is desirable, or, if that is not obtainable, a southwesterly or southeasterly slope, because either east, west, or north exposure will cause shade during a greater or less portion of the day.

"3. Standing, stagnant ground water, which cannot be drawn off by drainage, is to be avoided, the requirements of the plants indicating a somewhat damp subsoil, but not too high ground water."

For commercial purposes on a large scale, and when the trucker has the choice of location, a well-drained, light, deep, sandy loam, with a light clay subsoil, is to be preferred to any other. Heavy clay soil, or land with a hard-pan subsoil, or, in fact, any soil that is cold and wet, is totally unfit for profitable asparagus growing, unless it is thoroughly underdrained and made lighter by a plentiful addition of sand and muck.

Freedom from weeds is very desirable, even more so than great fertility, for the latter can be produced by heavy manuring, which the future cultivation will require; and to the end that weeds may be few, it is well that for a year or two previous to planting the land should have been occupied by some hoed crop, such as potatoes, beets, cabbage, etc. Land on which corn has been growing for two or three years is in excellent condition for an asparagus field, provided it has been heavily manured one year previous to the planting of the roots.

PREPARATION OF THE GROUND

Asparagus differs from most other vegetables in that it is a perennial, and when once planted properly, in suitable soil, it will continue to produce an annual crop for a generation if not for an indefinite period, while if the work is done carelessly and without consideration for the plant's requirements the plantation will never prove satisfactory and will run out entirely in the course of a few years. The establishing of an asparagus bed is naturally more expensive than the planting and raising of annual vegetables. In addition to this, the plants have to be taken care of for three years before a crop can be harvested. On the other hand, an asparagus bed is an investment for a lifetime, and the dividends derived from it increase in proportion to the care and thoroughness bestowed upon the preparation of the land.

It is at once apparent, then, that nothing should be neglected to bring the soil into the best possible condition before planting. This truth was fully recognized by the gardeners of former years who practiced most extraordinary methods in order to bring the land into the most favorable condition for asparagus. Even now in some European countries, where labor is cheap, the entire ground is trenched to a depth of three or four feet, turning in at the same time all the available manure, seaweed, and other fertilizing material.

A famous old-time asparagus bed in England was made in this manner: "The land was trenched three feet deep in trenches three feet wide and cast up into rough ridges, after a crop of summer peas. All decaying vegetation in the rubbish yards and corners was at the same time well sorted and turned up. Early in autumn also were added some old mushroom, melon, and cucumber bed material, a lot of manure from piggeries, cow houses, and stables, a quantity of road-grit and sand, a quantity of ditch and drain parings, turfy loam and sods, quite three feet thick. These were all turned over four times and well incorporated together, between Michaelmas and Lady Day, as one would a dungheap, the whole being left in large ridges exposed to the frost. By April this compost was in a kindly state; it was, therefore, laid down and planted with good, clean one-year-old asparagus plants, which certainly grew in a most extraordinary way."

Another elaborate way of making an asparagus bed, formerly practiced in France, is described by Dr. Maccullogh as follows: "A pit the size of the intended plantation is dug four feet in depth, and the mold taken from it must be sifted, taking care to reject all stones, even as low in size as a filbert nut. The best part of the mold must then be laid aside before making up the beds. The materials of the bed are then to be laid in the following proportions and order: Six inches of common dunghill manure, eight inches of turf, six inches of dung as before, six inches of sifted earth, eight inches of turf, six inches of very rotten dung, eight inches of the best of earth. The last layer of earth must then be well mixed with the last of dung. The compartment must now be divided into beds five feet wide by paths constructed of turf two feet in breadth and one foot in thickness."

A bed prepared in this manner, and planted and cultivated with as much painstaking care, will no doubt produce asparagus of unsurpassed quality, and may last forever. Yet the use of modern implements and a better knowledge of the nature and requirements of the plant have demonstrated that first-class asparagus can be produced with far less expense and labor. While a deep and loose soil produces earlier and better crops than a heavy and shallow one, indiscriminate deepening of the soil by trenching or other means is not always desirable, even where the cost does not come into consideration. When the subsoil is very light and poor and deficient in humus, the placing of the better surface soil below and the infertile lower strata above, trenching would be a positive detriment. The same would be the case where the subsoil consists of heavy impervious clay.

In the fall preceding planting the land should be plowed deeply and left in the rough state during the winter. Subsoiling has often been recommended, yet practical growers but rarely make use of the subsoil plow in the preparation of asparagus plantations, although the value of subsoiling where the subsoil is heavy can not be doubted. Where stable or barnyard manure can be had cheaply, and the soil is heavy, a liberal coat spread broadcast over the surface and left to the action of the weather during winter will ameliorate the ground considerably. In most cases, however, the same object may be obtained by applying the manure in spring. Joseph Harris mentions a case in which a bed was plowed and subsoiled in the fall and the soil filled with manure, while another bed near by was planted without manure, or extra preparation of any kind, relying entirely on artificial fertilizers after planting, and the latter was by far the better bed. As early in spring as the ground is in suitable condition to be worked it has to be plowed and harrowed and brought into as perfect condition as possible.

VIII

After the ground has been plowed and harrowed, or spaded and raked over, and brought into as mellow a condition as possible, the rows for planting are to be laid out. It is usually recommended to have the rows run north and south, so as to readily admit the sunlight. When this is not practicable, however, it need not deter any one from making an asparagus bed, as it is more important to have the rows run with the slope of the land than in any particular direction of the compass, in order to provide ready surface drainage.

DISTANCE TO PLANT

As to the best distance between the rows and the plants in the rows there is a wide difference of opinion, more so than with almost any other cultivated plant. No unvarying rule can be laid down on this point, as it depends largely upon the mechanical condition, depth, and fertility of the soil. In a rich, moderately heavy soil, the roots may be planted closer than in a poor, light soil. The tendency of the present day is for giving the plants considerably more room than what formerly was thought to be ample. Intelligent observers could not fail to notice that crowded asparagus beds produce later and smaller crops, and of inferior size and quality; that they do not last as long; and that they are more liable to attacks from insects and fungi than when more room is given to the plants.

Gardeners of but a few decades ago had no idea of the possibility of raising a profitable crop of asparagus planted four or five feet apart, and would have looked with derision upon any one advocating so wild a scheme. The remains of run out, old-time asparagus beds are still in evidence in many old farm gardens. The rows in these were originally one foot apart and the plants in the rows even closer than this, and perhaps after every third or fourth row there was a path two feet wide. Of course, in such a bed, after a few years, the entire ground became a solid mass of roots, and the stalks became smaller and tougher from year to year.

In most asparagus sections special customs prevail, and even in these different growers have their individual preferences; but all agree that asparagus should never be planted closer than two feet in rows three feet apart. For the home garden there is no better plan than to plant but a single row, with the plants two or three feet apart, along the edge or border of the ground, but not nearer than four or five feet to other plants, and in case of grape-vines even more room should be given. Here they require but little care, and the plants have an unlimited space for the extension of their roots in search of moisture and food. Asparagus needs considerable water, and an acre of land will hold so much water and no more. The more plants there are on an acre the less water there will be for each plant, and what is true of water is also true of plant food.

In field culture the distance adopted by asparagus growers varies from 3 x 3 feet (4,840 plants per acre); 3 x 4 feet (3,640 plants per acre); 4 x 4 feet (2,722 plants per acre); 4 x 5 feet (2,178 plants per acre); 5 x 6 feet (1,452 plants per acre); 6 x 6 feet (1,210 plants per acre), and even more. If the idea is to have the plants so far apart that their roots can not interlace, twenty feet each way would not be too extravagant a distance, under favorable conditions, as will readily become apparent by a glance at Fig. 14. This illustration is an exact reproduction of the root system of an asparagus plant four years from the seed. The roots spread out upon a level floor measured thirteen feet from tip to tip, the single roots averaging the thickness of a lead pencil. This root grew in Madison County, Ill., and was washed out of the ground—without having any of its roots torn—by the unusually heavy spring rains which caused the Piasa River to overflow its banks and sent a current rushing through the asparagus field in which it grew. If the plant had remained in its position a few years longer its roots would probably have extended ten feet in each direction.

From this it does not follow, however, that asparagus should be planted twenty or even ten feet apart to produce the largest returns, but it plainly shows why the roots should not be planted as closely together as was customary in former years; and it obviously demonstrates that when land is cheap and manure and labor high, asparagus can not be hurt by giving it plenty of room. It should also be considered that earliness, size, and quality make a great difference with the price and profits when early and large shoots are in demand. It might be possible to get double the number of shoots per acre from thick than from thin planting, but they might be so small and spindling as not to be worth the labor and expense of cutting and marketing.

DEPTH OF PLANTING

Contrary to the all but universal belief, asparagus is not a deep-rooted plant. In the wild state its most frequent habitat is on the fertile marshes of the shoreline in Europe, on ground but a few inches above the tidewater which permeates the sandy subsoil. As the roots can not live in water, they naturally grow to long distances parallel with the surface and retain this habit under cultivation. The tendency of growth in the asparagus roots in this direction is obviously demonstrated in Fig. 14.

The proper depth of planting asparagus roots varies somewhat, according to the character of the soil, the method of cultivation, and the kind of spears desired, whether white or green. As the new crowns rise somewhat above the old ones annually, it seems but rational that the plants should have sufficient room for the new growths before their crowns become even with the surface of the land. When the crown once comes near the level of the soil it is impossible to give proper cultivation, unless the entire bed be raised by adding soil to the whole surface.

While it is true that the deeper the crowns are planted the later they will start in the spring, this is of account only during the first few years. Besides, the factor of earliness is not of nearly as much importance now as it was before northern markets were so bountifully supplied with the southern grown crops several months before the opening of the northern season. Shallow-planted asparagus sprouts earlier, but soon exhausts itself, sending up spindling, tough shoots, while the deeper-planted crowns produce large and succulent sprouts throughout the season. When green asparagus is desired, and there is no danger of the beetles eating the sprouts before they are fit for use, a depth of two or three inches is sufficient, but for white or blanched asparagus a depth of from eight to ten inches is necessary.

MANNER OF PLANTING

As in other details of asparagus culture, the methods of planting have undergone very material changes. The formerly usual practice of digging deep trenches was not well founded—in the light of our present experience and knowledge—and could be useful only for drainage. How little regard was paid to the nature and requirements of the plant may readily be perceived by reading the following directions for making an asparagus bed, but little over half a century ago, in Bridgeman's "Young Gardeners' Assistant":

"The ground for the asparagus bed should have a large supply of well-rotted dung, three or four inches thick, and then be regularly trenched two spades deep, and the dung buried equally in each trench twelve or fifteen inches below the surface. When this trenching is done, lay two or three inches of thoroughly rotted manure over the whole surface, and dig the ground over again eight or ten inches deep, mixing this top-dressing, and incorporating it well with the earth.

"In family gardens it is customary to divide the ground thus prepared into beds, allowing four feet for every four rows of plants, with alleys two feet and a half wide between each bed. Strain your line along the bed six inches from the edge; then with a spade cut out a small trench or drill close to the line, about six inches deep, making that side next to the line nearly upright; when one trench is opened, plant that before you open another, placing the plants upright ten or twelve inches distance in the row, and let every row be twelve inches apart.

"The plants must not be placed flat in the bottom of the trench, but nearly upright against the back of it, and so that the crown of the plants must also stand upright, and two or three inches below the surface of the ground, spreading their roots somewhat regularly against the back of the trench, and at the same time drawing a little earth up against them with the hand as you place them, just to fix the plants in their due position until the row is planted; when one row is thus placed, with a rake or hoe draw the earth into the trench over the plants, and then proceed to open another drill or trench, as before directed, and fill and cover it in the same manner, and so on until the whole is planted; then let the surface of the beds be raked smooth and clear from stones, etc.

"Some gardeners, with a view to having extra large heads, place their plants sixteen inches apart in the rows instead of twelve, and by planting them in the quincunx manner—that is, by commencing the second row eight inches from the end of the first and the fourth even with the second—the plants will form rhomboidal squares instead of rectangular ones, and every plant will thus have room to expand its roots and leaves luxuriantly."

In diametrical contradistinction, and as an example of the very plainest and simplest of modern methods, Joseph Harris wrote: "If you are going to plant a small bed in the garden, stretch a line not less than four feet from any other plant, and with a hoe make holes along the line, eighteen inches or three feet apart, four inches deep, and large enough to hold the plants when the roots are spread out horizontally. Do not make deep holes straight down in the ground and stick the roots in as you would a cabbage, but spread out the roots. After the roots are set out cover them with fine soil, and that is all there is to it. Then move the line three feet from the first row and repeat the planting until the bed is finished. In the field make the rows with a common corn-marker, three feet apart each way, and set out a plant where the rows cross. It is but little more work to plant an acre of asparagus than an acre of potatoes."

Between these extreme methods many different directions for planting asparagus have been given and practiced. Modern methods have not only greatly simplified the planting, but have also materially reduced the expense, increased the crop, and improved the quality of the product.
