Tips for Pruning Climbing Hydrangea
Few plants can add the romance and cozy-cottage feeling to a garden like climbing hydrangea (Hydrangea anomala subsp. petiolaris, Zones 4–9) can. Whether it’s covering a semi-shady east-facing wall (an ideal spot), tumbling over a stone wall, or enveloping the trunk of a large, deciduous tree, climbing hydrangea can be a valuable asset, providing lush green foliage and masses of white, lacy umbels of flowers in early summer. Like many late spring and early summer flowering plants, climbing hydrangea is best pruned just after it blooms in late June so that new growth can form the next year’s flower buds by late summer. However, pruning right after blooming isn’t always practical because, like most vines, climbing hydrangea is a vigorous plant once established, and it can be difficult to see the overall structure of the plant with all of its leaves in full flush. Some selective pruning may need to be done nearly any month of the year, and that’s totally OK. But if you prune anytime from fall to spring, you may sacrifice some flowers.
