Hi--I'm brand new to the forum and hoping someone can tell me what happened to my crape myrtles so that I don't do it again! We planted four Tontos about six years ago. We cut them back every spring and they performed beautifully. This year, they started to grow from the top as usual, then we had another cold snap (we're in west central FL) that killed the new growth. That's happened in other years, with no resulting problems. This year, however, the trunks split a bit, now nothing is growing on the top, but new growth is coming from the ground. The trees trunks are about 4 1/2 ft. tall, so I'm really upset. Does anyone have any thoughts as to what might have happened? The temp here only goes down to the mid-20s. Thanks for any help anyone can provide.
