Q.I Have Many New Crepe Myrtle Trees Growing In My Garden.
I have one main crepe myrtle tree however there are many new ones popping up throughout my whole garden. There must be at least 15. How do I stop that from happening?

It sounds like they are self seeding! This is quite rare, but likely means you obtained a naturalized cultivar rather than a modern hybrid.
Those unlucky enough to have one of these will notice, quickly, how much of a pain in the behind they will become.
Other than keeping them cut to the ground, applying pre-emergents, and applying weed barriers, there isn't much that you can do.
