I planted crape myrtles in my full-sun front yard in May of this year. I just recently moved one to another spot and now it looks like it's dying. I water in almost everyday and I have used a root connector. What else can I do to save it, I love my trees.:)

It is probably just relocation shock to the roots. Crêpe myrtle does need a lot of water but I think you should back off a bit until you see some new growth.

Did you lose much of the ball when you took it out of the ground? A nursery tree 4months in the ground would not have started any growth into the new soil. It should come right out of the ground without much effort. I agree that watering everyday is not good. A soak once a week is more than sufficient.
