Slow-release fertilizers with built-in pesticides are available. Or feed with a liquid fertilizer once a month. Stop feeding two months before your region's first frost date in fall to prevent tender growth being damaged by cold weather.Make sure your roses get 1 to 2 inches of water each week during the growing season, and a bit more during hot, dry periods. Water deeply, and avoid getting the leaves wet.

Planting
Plant shrub roses in well-drained, slightly acid soil. Add organic material to loosen compacted soils. Choose a spot that gets at least six hours of sunlight a day. To ensure good airflow, which helps prevent disease, space shrub roses 5 - 6 feet apart; twice that distance in warm areas.Position the bud union -- the knobby section that joins the roots to the main stems -- right at soil level.

If you live in a region where temperatures drop below 20 degrees F., plant the bud union one inch below the soil surface.Water well. If planting bare-root roses, mound several inches of soil over the base of the rose to prevent it from drying out until it becomes established. After a couple of weeks, gently push or hose off the soil.

Pests and Diseases
Black spot and powdery mildew are common in humid areas. Plenty of sun and good air circulation reduces the problem. If needed, an anti-fungal spray in early spring can help control the problem. Aphids are also common; spray hard with a hose to reduce populations.

Japanese beetles are common east of the Mississippi For minor infestations, remove the beetles by hand or shake them off plant into a bucket of soapy water. For major infestations, apply chemical controls according to package directions.
