I have a young crepe myrtle that was planted in late spring. It gets full sun most of the day. It is about 18" to 24" tall. It did bloom pretty well. It now has no flowers, only pods where they once were. It also has few leaves, some look damaged. The leaves are orangeish and green with some yellow. I don't see any bugs. It is mulched and, at the time, we had ants around it so we sprinkled a little ant bait on the mulch. That was about a month and a half ago. Help please.
