About This Book

This extension bulletin offers practical guidance to select and place woody shrubs in Kansas yards, matching species and varieties to site conditions and intended landscape uses (accents, borders, screening, privacy, erosion control, groundcover, transitions). It explains how size, form, color, and texture affect visual impact; advises placement around entries, corners, windows, and foundation lines; recommends staggering blooms to achieve continuous seasonal interest; and describes size and evergreen/deciduous categories. Tables and plant descriptions help compare expected mature size and performance, and nursery-selection notes assist readers in procuring appropriate cultivars for local conditions.

PROBLEMS TO EXPECT

Every shrub species grown in Kansas can be expected to be afflicted with some problem during its lifetime. The most common problems are insect and disease attacks. These usually can be controlled by routine spraying. Knowledge of the problems make it easier to diagnose and correct before they become severe.

Soil alkalinity or high pH may also limit the use of some plants. Iron chlorosis is a common problem with some shrubs grown in the western half of Kansas. This is easily corrected by applying iron sulfate or iron chelate to the plant or soil.

Your local County Extension Agent can assist you with the diagnosis of any disease, insect, or cultural problem.
