The Q&A Archives: Pruning and Training Mimosa Trees

Question: I have mimosa trees that are between one and two years old. Some have very long, lower growth branches. Are there any general rules on how to trim the mimosa so that it develops into a good shade tree?

Answer: Mimosa trees should be pruned in the early spring, taking the branches back to 5-6 buds. If there are only a few very long branches on your tree, you can clip them back now, but for general pruning, it's best to wait until early spring.

It's difficult to predict just how each branch will develop new shoots, so some summertime pruning may be necessary for the first few years.

Best wishes with your mimosa!
