When should you prune Annabelle Hydrangeas

Question

Should you cut back in the fall, and how much?

Answer 1

Generally you prune in the summer after they are done flowering.
You can also cut them back in winter or wait until early spring to trim back the old growth.
I personally trim the plants in the spring prior to leaf out and I am just south of you.
