Consulting Rosarian Tips
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.
Rosarian Tips for June:
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.
