Monarda 'Marshall's Delight' problems — and how to fix them
Monarda 'Marshall's Delight' (Monarda didyma 'Marshall's Delight') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Powdery mildew
Highly resistant but not immune; drought stress and stagnant air can still bring it on. Keep soil moist and ensure good airflow.
Spreading clumps
Rhizomes creep outward and may crowd neighbours. Divide every 2-3 years to control spread and maintain vigour.
Bare-centre clumps
Mature clumps hollow out in the middle over time. Replant the healthy outer divisions and discard the spent centre.
Floppy stems
Insufficient light or overly rich soil causes weak, leaning stems. Grow in full sun and avoid excess feeding.
