Consulting Rosarian Tips for May:

Pruning can be done this month.  Prune canes back to green stems and an outward facing bud eye.  Remove old leaves, trash and other debris from your garden.  When pruning, always seal canes with cane sealer, Elmer's glue or colored finger nail polish to prevent cane borer damage. 

Consulting Rosarian Tips for June:

Continue watching for aphids, thrips,  spider mites and leaf rollers.  Use organic or chemical spraying programs to control. Begin watering deeply at least once a week.  Fertilize using either a water soluble fertilizer or an organic fertilizer such as Mile High Rose Feed.  Cut spent blooms to promote continued flowering.  Start watching for powdery mildew, blackspot, anthracnose, and rust.  Use organic or chemical spraying programs to prevent and control.    

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

2014 Roses in Review Results

Every year, the American Rose Society conducts a survey of roses and how they grow in garden around the nation.  The results for the Rocky Mountain District are in.  See what rose growers in Colorado, Wyoming, Idaho, Montana and Utah have to say about recent introductions.  Use this information to help you decide which roses to plant next year. 

The book, Growing Roses in Colorado, published by the Denver Rose Society is a "must have" for those who want to grow beautiful roses successfully.  Get a glimpse inside the newly revised Growing Roses in Colorado.  Available at area garden retailers and gift shops. For wholesale inquiries please contact Betty Cahill at
