Hydrangea Has Never Bloomed

Question

My hydrangeas have never bloomed. They are 3 years old. I have cut back every fall. I do not know what kind I have but am thinking it must be the kind that blooms on old wood. Should I cut back in summer instead of fall or should I not cut back at all to see if it blooms next year.

Answer 1

It could be that you have the macrophylla type that blooms on old wood like you say. Trimming it in fall would indeed cut off the blooms. Do not prune again till it blooms. Then if needed you can prune soon afterwards.

Lack of light can be a problem, too. Most hydrangeas need at least partial sun. Here is more about why a hydrangea may not bloom:
