When To Prune Crapemyrtle in Virginia?
I have three 'Tonto' watermelon red variety of crapemyrtle that are about 4 years old and are 5 to 6 feet tall. They look like shrubs, but I would like to train them to have the appearance of a small tree.
Can I do this type of pruning now---in March? And how many stems can I safely prune out without ruining the health of the plant? One-third? Could I prune out half the stems, or would that hurt the plant?
