Q.Pruning a Loropetalum tree
I am afraid that my husband may have over pruned our Loropetalum tree. It had gotten way too large for where it was located. He pruned it this past fall similarly to the way he prunes our crepe myrtle trees. There were no leaves left. It is February and I see no signs of new growth. Not concerned that it won’t bloom this spring, but sure hope the leaves return. Help!

It is likely your Loropetalum will recover over time, but you will lose flowering this season.
