|I have a lacey top hydraenga and have been told if I prune it, it will not flower next year.
The plants are getting much too big. Can I prune them and if so when.
|I'm not sure where you got your information about not pruning hydrangeas, but it is incorrect. Hydrangeas are routinely pruned in the very early spring, just as new growth buds swell on the canes or stems. You can safely prune yours back by one third and it won't affect its ability to flower. If yours has finished flowering now, you can prune it back now. Hope this clarifies things for you.|
