Blooms weighing down branches
Hi I was wondering if someone could advise me on what to do. I have a 4 1/2' tall Nikko Blue that blooms beautifully, the only problem is that it's stems are very thin and so the blooms ends up laying on the ground. I recently went to Massachusetts and walked around the neighborhood as I couldn't resist inspecting the hydrangeas up close. To my shock, the stems were quite thick - 3/4 to 1' in diameter. Is there any way to encourage this? Should I prune (next year) immediately after flowering? Thanks, all!
