Can a Climbing Rose Bush Be Pruned in the Summer?

Climbing roses make living arches.

Climbing roses bloom through the summer. These perennials grow on long, flexible stems. The stems, or canes, train easily to fences, arbors and other supports. Though climbing roses are typically pruned in early spring, they benefit from light summer pruning.

Maintain

During the summer, climbing rose canes are often damaged by weather or accidents. Prune dead or damaged canes at a strong bud union or at the cane base. Prune off diseased canes promptly as humid, warm summer weather encourages spreading of mildew and other diseases.

Deadhead

Cut fading flowers and their stems down to just above green foliage. Deadheading renews the plant because energy is no longer diverted to wilting or dying flowers. This light pruning encourages future blooms on the cane.

Shape

After spring bloom, many gardeners shape climbing roses. Prune overlong canes back to the desired shape. Vigorous canes can be thorny hazards to people or pets. Trim them back and tie them in place along the fence or trellis support.

Uses

Plant vigorous climbers along an old fence or storage shed and watch the roses turn an eyesore into a magnificent summer bouquet.
