Prune them too late, and you'll remove flower buds. Many other vines flower on the current season's growth and generally bloom in midsummer and autumn. Prune these types of vines, including silver lace vine, trumpet vine and climbing hydrangea, in early spring. Certain climbers, notably wisteria and grape, blossom or fruit on old growth. Prune these types during the dormant season shortly before growth resumes in spring.
Vines are truly a versatile, blue-chip investment among plants.
They're also living proof of just how beautiful practicality can be.
