If I were to slightly cut branches on crepe myrtle tree to even them out, would it make the tree stay short or would it still get taller? I cannot seem to find any information that tells me anything except thinning out, but nothing on getting the tree to grow tall. Am I supposed to trim the branches shorter each dormant season? I have one or two branches that are a lot taller than the rest. Thank you. I am in zone 8, Morgan City, Louisiana.
