Growing Hydrangea in Tree Form
What are your experiences with growing a hydrangea in tree form? If you buy one from the nursery in tree form, can you plant it like a tree and you're good to go or do you have to constantly keep pruning it to keep it in tree form? I know it would need to be a paniculata, but are there some that you've found that work better than others for this purpose? Once established, do they need as much water as macrophylla hydrangea shrubs?
