Frost Got Hydrangeas

Question

We had four nights of mid 20’s temperatures. Now my hydrangeas are brown, both stems and leaves. Should I prune them to the ground? They are about 3 feet tall now. Not sure what to do.

Answer 1

I would not prune them right now. Most hydrangeas bloom on old growth, so if you prune, you will lose the blooms next year. They will regrow their leaves when spring comes, as long as the stems are alive. I would wait until spring and once you see what stems have died, you can trim them away.
