Hydrangeas – How To Prune Them

Q: I heard your radio discussion about pruning hydrangeas. Do I cut just the green new growth stem or can I cut the old wood too?

A: You can cut into the old wood if you need to. Make your cuts a half-inch above the spot where two leaves emerge. The next few weeks give us the perfect window to reduce the size of hydrangea shrubs. Their blooms are fading fast and they will have plenty of time to grow the bloom buds that will produce flowers next year.
