How to Troubleshoot Home Run Rose Problems

Overview

Home Run roses are a hybrid known for their resistance to black leaf spot and powdery and downy mildew, three of the most prevalent diseases that afflict roses. These shrub roses have a rounded form and grow to 4 feet tall. They produce fire-engine red single petals from summer to frost and are self-cleaning, meaning they don't require dead-heading. Like all roses, they need six hours of sun each day and plenty of water. Minimize the effects of pests and diseases by keeping them strong through proper watering, fertilizing and pruning techniques.

Step 1

Inspect the blooms. Home Run roses produce bright-red blooms from summer to frost. If your plant is not blooming, the probable causes are lack of sunlight or lack of water. These roses need at least six hours of sunlight daily and at least 1 inch of water per week. Move roses that don't receive adequate sunlight to a sunnier location. Water your roses deeply two or three times per week during dry periods, keeping the soil evenly moist, but not soggy.

Step 2

Inspect the leaves and canes of the Home Run rose shrub for disease. Although this shrub is disease-resistant, it may not be completely immune. Orange pimples on the underside of the leaves indicate rust, and brown areas on the stem are canker. Remove diseased canes and leaves with your pruning shears and apply a fungicide according to package directions.

Step 3

Look for signs of insect infestation. Spider mites make webs on the undersides of the leaves. Aphids leave holes in the leaves. Hose these pests off with water, or apply dormant oil spray in the winter.
