Finding the Right Site
Roses do best when they get at least 6 hours of direct sun per day. Morning sun dries the foliage early in the day, which may be wet from overnight rainfall or morning dew. Dampness can encourage fungal diseases so provide adequate sunshine and air circulation around each plant.
Curtailing Cane Borers
To stop cane borers from doing further damage, you have to prune back the affected canes below the hole. Inspect your canes for signs of recent activity. You can pull the grubs out of the holes by hand. Then seal the hole with a dab of Elmer's glue or a thumbtack.
Preventing Powdery Mildew
The best way to control powdery mildew is to prevent it. Water early in the morning, avoid wetting the leaves, provide good air circulation, and be vigilant!
Fertilize Roses With Banana Peels
Banana peels make an excellent fertilizer for your roses. They add potassium to the soil, which is needed for big, beautiful blooms. Potassium also promotes plant vigor. For best results, shred the banana peels into small pieces. One application a month is all that's needed.
No Room For Roses?
Roses grow well in containers if garden space is at a premium. Use a 16-inch pot to accommodate roots, and fill with a good grade of commercial potting soil. Remember that potted roses must have winter protection because their roots are exposed to winter air temperatures. Put them on wheels, and wheel them into an unheated garage for the winter.
