I planted a new Dynamite crapemyrtle (Lagerstroemia indica 'Whit II') in May this year. It's about 4 feet tall and appears to be thriving well. But I've noticed shoots/suckers near the base of the tree...should these be trimmed off of the tree to allow for better overall health? Thanks .
Yes, you should prune them off. Not so much for the health of the tree but to keep its shape. If you allow the suckers to grow the form will be more shrub-like instead of a tree.
