Question:
I have powdery mildew on my bee balm plants that I just bought this year at sunnyside. It has spread to most of the plants. There is new growth coming up from the ground and off some of the infected stems. The plants are in our butterfly pollinator garden so we are not using any chemicals, pesticide fungicide spray free garden. I have found a few natural spray solutions. Should I also cut out all the infected part of the plant to keep from spreading g to new growth? Thanks.
