When to prune Hydrangea 'Pink Diamond'?
I just added a new 'Pink Diamond' Hydrangea in the fall. It's a standard with a trunk and I would like to prune it in such a way that it will provide as much support as possible for the flower heads, so there is less flopping. I don't see any buds swelling yet and wondered if I should be by now? And if I should start pruning it now regardless of not seeing any growth?
