White Powder on Leaves
I have recently noticed a white powder on the leaves of my Crape Myrtle. The leaves are growing out, looking gnarled and unhealthy. What is it and what can I do to get rid of it? I live in South Texas, where it is always hot and humid.

Your crape myrtle probably has powdery mildew, which this shrub is very susceptible to in hot and humid weather. Spray it with a mixture of 1 tablespoon of baking powder and a few drops of mild dish detergent in 1 gallon of water. Clean up and discard the dropped leaves. Improve air circulation around the plant by pruning back adjacent plants, if possible. Or you could replace the crape myrtle with a mildew-resistant cultivar like 'Tonto' or 'Zuni.'
