Hi, all -- happy spring, and I hope you're all staying safe. I brought this Sioux Crape Myrtle back at the end of last summer. Now that it's leafing out, I see that the tips of almost all the branches are dead. Does anyone know what this might be? Could it be winter dieback, or something more serious? It was a very mild winter. I'm in zone 7B. I'd greatly appreciate any suggestions on what to do next. Thank you!

Maybe or it could be where last season's clusters of flowers used to be? I get some of that too but, as the small new foliage gets larger and larger, the sticks disintegrate or disappear on their own. No need to do anything...

Thank you, Luis_pr, this is helpful. Do Crape Myrtles only bloom on new growth?

Yes. Some varieties will also rebloom if you give them a crew cut after the first flush. I have not tried with mine because they are almost three stories high but a neighbor has dwarfs that get a crew cut after the first flush of flowers and then those guys bloom again. Not as much as on the first flush but decent enough. Thanks to the winds and the birds -who eat their seeds- CMs are almost like a weed here. But in the few years that the neighbor has had those dwarfs, I have not seen their blooms pop up nearby; makes me wonder if the dwarfs are being sold sterile. Anyways, they should be almost maintenance free in Z7b. Pruning is not recommended and is rarely needed if planted where it can attain its estimated size at maturity in the plant label...

PS - I forgot to mention that over here, CMs are very late to leaf out. I do not know if some of those dead looking areas will therefore leaf out in a few weeks.
