Why is it so scary to prune Nikko Blues?
Whenever I ask people about pruning their nikko blues,m or even researching on the internet, I keep finding the same answer: Dont prune them. If you prune them, they wont bloom.
I have a few properties that I work on where the hydrangeas must be pruned to give it a nice shape. So last year, I just went for it, in November. I took about three feet off of all of the Nikko blues and gave them a nice shape. I also took off the oldest looking canes to the ground. I warned the homeowners that the hydrangeas woould not bloom the following year. They aggreed that it would be worth it because the hydrangeas had gotten to be too big. The next season, They BLOOMED! What the heck!?
Should I prune them every year in November? I thought for sure that I had pruned off the buds.
