Q: My three-year-old French hydrangea has never bloomed. What can I do? (October 1971)
A: The three most common reasons for this are: winter cold killed the flower buds; not enough sun; and pruning at the wrong time. You can address these by planting reblooming types like ‘Endless Summer,’ ‘Big Daddy,’ and ‘Dear Delores;' giving your plant at least a half-day of sun; and pruning immediately after the blossoms fade.
