Baking soda and white distilled vinegar are amazing to clean with. Just google for uses. The only problem is if you don't like the smell of vinegar but it does go away after awhile.


For Crape Myrtle powdery mildew I spray a solution of 1 tsp baking soda and 1 quart water and a few drops of liquid soap. I sprayed once a week until it looked like it worked. I only sprayed the affected areas. When the leaves drop make sure to rake them up and dispose of them. I found this idea online but have forgotten the website. It seemed to work but my Crape Myrtles are pretty small (about 6 foot) so it was easy to reach the areas with just a spray bottle.
