How and when do I prune my hydrangea?
Endless Summer Hydrangea
Endless Summer Hydrangea should not be pruned the first year. This will give the plant time to get established. After the first year you can remove up to 1/3 of the old stems from the plant. Remove the stems in the fall, after the leaves have dropped. This makes it easier to shape the plant. Mulch at the base of plant to prevent winter damage.
Big Leaf and Oak Leaf Hydrangea
These varieties bloom on old wood. To determine if your hydrangea blooms on old wood, think about when it flowers. If it blooms in early summer and finishes blooming by mid-summer, it blooms on old wood.
These shrubs form next year’s blooms in late summer or early fall. To make sure they bloom next season, prune just as the flowers begin to fade. The earlier you prune after bloom, the quicker the shrub will recover, producing more and larger blooms for the next season.http://www.danvillegardens.com/
