Hi, In the past three years since we bought our house I've been experimenting with different plantings here and there. Our lot is mostly shady (varies from dappled to deep shade) with a few areas that get steady sun for about 5 to 6 hours. I made up my "sunny" flower garden in one spot that gets about 6 hours of sun (from 9 to 3:45). Most of the stuff I planted there (foxglove, sweet William, daylilies, clematis) are doing well except for the bee balm I planted two years ago. It's growing (and spreading) but it gets powdery mildew every summer which ruins most the flowers. I think I've read that bee balm likes to be in a moist spot and that powdery mildew is a sign that it's being kept in a too dry location. Sort of opposite of what I had thought. I would rather have plants that didn't need special treatments to stay healthy so it's either transplant the bee balm to a better location or just rip it out.
I do have some spots that are nearly always moist (along a ditch which has running water all year unless we have a drought) and along the length it varies from dappled shade to 6-7 hours sun. So if I was to transplant my bee balm, where should I put it?
