When is the best time to cut back an overgrown oak leaf hydrangea? Mine is in bloom now & is about 5' tall and very narrow as it is growing among many other plants.

I cut back the old growth and do a general trim in the late fall.

If you trim in the fall, make sure it's late enough that a trim is not going to encourage new growth before winter. The new growth might not have time to harden off before cold weather. I would trim either right after blooming or in the spring.
