undying crepe myrtle
kathycot

When I moved into my house there was a crepe myrtle at the corner of my driveway, it was in bloom at the time and looked beautiful; at first glance. I then started noticing the red leaves and the white powdery stuff covering the stem and some of the leaves. I asked several "experts" at greenhouses about it and was told it could possibly be white flies, except for the red leaves. To make a long story short it was decided it might be diseased because the same thing happens every year it blooms. I decided to cut it down and dig it up to get rid of it.... It spreads into the yard every year! I was told to try putting stump killer in the stump I had left and that will take care of it. Nope! Almost 15 years later I am still fighting with the crepe myrtle. Now whatever disease it has apparently has moved to the g**** vines I planted last year nearby. Herbicide also does not work and it laughed off the stump remover.

It sounds like you have a powdery mildew on your plants. It usually isn't fatal, but can be controlled with a fungicide. Look for something specific for gr-apes.
Crepe myrtles shouldn't be that hard to kill. Dig or grind out the root and hit any young shoots with glyphosate. It may take a few sprayings.

Some southerners like Crepe Myrtles and some of us call them "Crap Myrtles" after becoming weary with dealing with the huge mess they dump all over the lawn. I like them in your yard, but not mine!

Ed21 has the eradication method right and I think it's powdery mildew too. Take some affected material to your local garden supply in a ziplock bag to have them confirm that. This can be easily treated.
