The Q&A Archives: Pruning Anthony Waterer Spirea

Question: I have a few Anthony Waterer Spirea shrubs. When and how should i prune it? I've left the dead blossoms on it and it's just as it was when cold weather came a few months ago. A friend told me I could cut it down to the ground with ease, but i want to confirm with you. Thanks!

Answer: Spiraea x bumalda 'Anthony Waterer' blooms on new growth of the season, so it is pruned in late winter to early spring. Cut it back quite hard, by about two thirds or so, to remove all winter damaged stems and to create a symmetrical shape. Do this before it begins to leaf out. After the first big flush of blooms, you can shear it all over lightly to deadhead and encourage additional blooming later in the season. Enjoy your spirea!
