The Q&A Archives: pruning oak leaf hydrangea

Question: We have 3-oak leaf hydrandgea that had to be braced this year. Can we prune 20-30% after they have gone thru their blooming period?

Answer: The usual time for pruning hydrangeas is in the early spring, before they leaf out, but you can certainly prune yours back now if they are so overgrown they need to be supported. The general rule of thumb is not to remove more than one-third of the live material from a shrub or tree. If you need to remove more, you can do it in stages; one-third now, one-third next spring, and more as needed the following spring. Best wishes with your hydrangeas!
