Q: Can I prune my Penny Mac hydrangeas now? I’ve been afraid to prune for fear of not doing it correctly.

A: Rejoice! You can prune your ‘Penny Mac’ now and still have flowers next year. Most mophead hydrangeas bloom on a set of buds that formed the previous fall. ‘Penny Mac’, though, is a remontant hydrangea. Like ‘Endless Summer’, it forms flower buds throughout the summer, even after being pruned late the previous year. You won’t have blooms early next summer but they will begin appearing in mid-June.
