Q.crepe myrtle problems
I planted a few different types of crepe myrtles this spring and they have been doing great, but 3 of them that are the same kind (they are either Muskogee or Tonto–have thin trunks. . . lighter yellow leaves) are starting to lose leaves, which are browning up. It is not for lack of water and the rest of trees are great. Please help.

If you are certain that the tree is getting enough water, then I would look for pests or fungus. Treating the plant with a pesticide and a fungicide will not hurt it and will take care of these issues if they are the problem.
