I have a Red rocket crape myrtle that I planted last year. It's blooming just fine but the leaves are turning splotchy yellow and falling to the ground.
I live in Dallas, TX. As you guys know, it has been very hot and dry this summer. I've watered the crape myrtle about once a week during the hottest time period but I don't feel that water is the cause of the problem.
I've looked up leaf spot and it looks similar to that, but our lawn service guy says its not- he says that this is an issue caused by the excessive heat. Is that true? If not, I need to treat the tree. If it is true, however, I guess I can't do much but watch the leaves fall off and wait until next spring.
As a side note, excluding our roses (which bloom but look a little sad), all the other plants near the crape myrtle seem fine with the heat and watering regiment.
