Macrophylla hydrangea

Asked September 22, 2015, 5:08 PM EDT

Hi Experts, In all of the on line info. I read about pruning macrophylla hydrangeas, if you prune them in the spring. You have cut off the flowers. I have a Hydrangea book that claims, if you make your cut above two buds, a flower will bloom there in the summer. Assuming that you don't get a late freeze. Thanks, Colleen Ward

In recent years mother nature and low winter temperatures have been pruning them for us. In warm climates prune after flowering. In colder climates (think last winter in Maryland), leave the old flower heads on over winter and prune in midspring when you can see what has survived the winter. The old cultivars of Hydrangea macrophylla bloom only on old wood. This old wood can be blasted by cold, killing the flower buds. Newer culivars bloom on old and new wood and are a better choice for Maryland with its fluctuating winters. vw
