Spotted Bee Balm problems — and how to fix them
Spotted Bee Balm (Monarda punctata) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Powdery mildew
The most common problem, especially in humid climates or crowded plantings; choose a sunny, open site with good air circulation, avoid overhead watering, and space plants at least 45 cm apart.
Short lifespan / failure to persist
Spotted bee balm is biennial or a short-lived perennial that relies on self-seeding to persist; avoid deadheading all flowers — leave some seed heads to allow natural reseeding, or collect and sow seed each autumn.
