Q: Not one of my Endless Summer hydrangeas bloomed this summer. What did I do? I’ve had them for several years and always a good show.

A: If they have good green foliage they will eventually bloom this summer. The problem might be some after effect of the cold winter. Avoid pruning off new flower buds forming at the tips of stems now. And, in the spring, do not cut “dead” stems to the ground until new leaves have completely expanded, often not until early June.
