Last year I bought two really nice Dynamite Crape Myrtles, about 5' high to plant on my side yard next to the driveway.

Well, my DH managed to run over one of them with his pickup, damaging a couple of the trunks. Don't ask...I left about three suckers to take the place of the damaged trunks, and it is blooming it's head off! The undamaged crape myrtle is doing absolutely nothing. I've checked, it's alive, looks healthy, just no blooms.

Any ideas?
