Troubleshooting
Wild Bergamot problems — and how to fix them
Wild Bergamot (Monarda fistulosa) 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
Its most common issue; white coating disfigures foliage in humid, crowded or shaded sites. Choose airy positions, space plants well, and select mildew-resistant cultivars.
Rhizomatous spread
Forms expanding clumps that can crowd neighbours; divide every two to three years to renew vigour and control size.
Centre die-out
Older clumps die out in the middle as they spread outward; lift and divide, replanting healthy outer growth.
Drought stress flagging
Wilts and drops lower leaves in prolonged drought despite its tolerance; mulch and water deeply during heat waves.
