What’s in Bloom, Week of May 28

— Written By

This week, spring-blooming hydrangeas are starting to flower in our area. There are many different types of hydrangeas. One common question gardeners have is “when do I prune my hydrangea?” Hydrangeas that bloom in the spring are blooming on old wood, meaning their flower buds formed in the fall. Wait to prune these varieties until just after they have finished blooming. This Guide to Pruning Hydrangeas from Maryland Cooperative Extension can give you more details.

Don’t forget to visit our What’s in Bloom page for even more photographs of what’s blooming, as well as details on where to find them.
