This is my 2nd post in one day! I'm either failing as a gardener or just having some bad luck. I planted 6 miniature crepe myrtyles this past spring. They have been very healthy and are starting to bloom (I live in Maryland). I noticed though last evening that 2 of the plants have a white powder on some of the stems/bloom pods. I'm assuming this is powdery mildew. It has been very humid here, so I'm also assuming it is from the humidity. The plants were all planted with plenty of room in between, so I don't think I crowded them. I found a recipe for treating this on the internet, but I wanted to verify with the experts here that this is a good formula: Mix 1 tablespoon of baking powder (or should it be baking soda?) and a few drops of mild dish detergent in 1 gallon of water and spray on plant. If this is not a good formula, I would appreciate any recommendations. I want to go the more natural route in treating the problem. Thanks!
