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?
