Can I prune my Strawberry Sundae hydrangea this fall after a frost or should I wait until Mar? Thanks Kathy Reimers in Rochester Mn
Olmsted County Minnesota
You can prune it any time until late winter. It blooms on new wood, so you want to make sure to do it before spring growth starts. I leave my flowers over the winter for interest and for the birds, but you can prune them in the fall if it is easier for you.
