Q.Why Is My Young Crape Myrtle Bush Suddenly Wilting?
We planted a crape myrtle bush in the spring in my garden in the northeast. As instructed, I watered it daily. Within 2 weeks, many of the leaves curled up and dried. I removed them, and vigorous new leaves and shoots appeared throughout swveral weeks of sustained 90 degree heat and humidity. It bloomed on every branch for the past two weeks. Suddenly yesterday, the leaves and flowers wilted. I watered it, and today it looks even worse. What can be done to reverse the wilt and save it?

Likely, wet soil that didn't dry out, adequately, was the start of the problem. This will invite disease, of which there are many, that will take over in the heat. In response, a plant will go into shock. This can include flowering in order to have one last attempt to reproduce, to allow the survival of the genetic line.
Likely, this has lead to infection that, ultimately, will cause its demise.
I would start over in a new part of the yard. Treating severe infections can take a couple of years. Make sure to allow the new shrub to dry down to a few inches, thoroughly, between waterings.
