Just to confuse you, over-watering Monarda has the same effect as under-watering. Droopy leaves. It seems that if it was under-watering, the leaves would dry up, not just droop.
Also, is it planted in loose, fast draining soil? Although Monarda like to be constantly moist, they do not like to be constantly soggy.
