Hydrangea that bloom on old growth should only be pruned after flowering. To reduce the risk of removing any newly forming buds, prune just as the flowers begin to fade.

Using a sharp pair of pruners, begin by removing dead, diseased, and damaged wood, cutting back to healthy growth and stem joints.

Step 3: Reduce Stems

Prune Out Oldest Wood All Over Plant

Prune Out Oldest Wood All Over Plant

When a shrub gets old and woody, it can produce smaller blooms. Regular removal of a few of the oldest canes at the soil line can keep the shrub vigorous, producing large and abundant flowers.

Cut out up to one-fifth of the oldest wood all over the plant, reducing stems to within 2–3 inches (5–8 cm) of the ground. It is easiest to do this with a pruning saw.

Step 4: Remove Weak Growth
