Oregon has some of the best rose growing country in the world. Unfortunately, the same conditions that favor roses also favor the diseases and pests that plague them.

Because of their disease and pest problems, many home gardeners perceive roses as "trouble plants." But roses need not be difficult to grow. Simple adjustments in rose care can improve the health of your plants with a minimum of pesticide use.

The Oregon State University Extension Service offers a handy publication that takes some of the mystery away from keeping your roses healthy, called "Controlling Diseases and Aphids on Your Roses."

This six-page circular is packed with information on the most common rose afflictions: black spot, rust, powdery mildew and aphids. It identifies conditions that favor infection and suggests practices to help effectively control these problems. Rather than discussing controls for each specific problem, the OSU publication treats the rose as a whole organism. It offers a year-round integrated approach to pest and disease control.
