I have a crepe myrtle that was pretty much destroyed by my dog. I was waiting to see if it would somehow grow back, and it is growing some sort of new buds on the remaining areas of the trunk. My question is will this crepe myrtle ever get big again, and is there anything I can do to help it grow healthy again? It now has a barrier around it so my dog cannot chew on it. I am including photos, too. Thanks!
