Out of control hydrangeas #928868

Asked April 19, 2026, 1:09 PM EDT

I bought this house last summer and inherited these overgrown hydrangeas. I don't know what to do to fix them. Can I cut them all the way down? I don't want to kill them.

Expert Response

Yes, they can be cut off down to about 6-12 inches, but before pruning it would be best to let it bloom this year to identify the kind of hydrangea from its flower.
