My crepe myrtles a week ago were blooming and in good condition just gorgous but now looks like the leaves are withering and the blooms have all die. Looks like it need watering but have been watering it. Temperature have been up in high 90's. Any one know whats wrong???

Claudia-
Crepe myrtles are very hardy, adapted trees. Something strange is going on. I would call a professional like Soils Alive. I doubt he would charge you more than $50-75 if he did at all. Ask him (Michael) to bring a camera, he can probably take a picture to Howard if necessary.
