I'm trying my best to get rid of a crepe myrtle. About 1 1/2 years ago I chopped it down. It grew back. This spring, I dug out a lot of the roots, but it's growing from where I chopped the roots. Would something like Roundup or a brush killer do the job so I don't have to get pulling out the new growth.

This is some type of native, wild plant. Originally planted about 12 years ago from a volunteer in my Mom's yard. Now too big for the location and hope to plant something smaller (shrubbery) in the location.

It seems a crepe myrtle is Hydra like.
