Consulting Rosarian Tips for July:

Continue watching for aphids, thrips,  spider mites and leaf rollers.  Continue watching for powdery mildew, blackspot, anthracnose, and rust.  Use organic or chemical spraying programs to control pests and prevent/control disease.  Don't spray when windy or if temperatures are over 85 degrees. Continue deep watering, more frequently as the temperatures rise.  Fertilize once a month using either a water soluble fertilizer or an organic fertilizer such as Mile High Rose Feed.  Be sure roses are well hydrated before fertilizing or spraying.  Cut spent blooms to promote continued flowering.  Apply additional mulch around bushes to bring level to several inches dept to conserve water and keep the soil cooler.

For rose questions, contact a Consulting Rosarian in your area.
