Troubleshooting
Double-flowered Chamomile problems — and how to fix them
Double-flowered Chamomile (Chamaemelum nobile 'Flore Pleno') 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.
Rot in wet or heavy soil
Poor drainage and overwatering rot the crown, especially in winter. Use light, gritty, free-draining soil and let it dry between waterings.
Few flowers
Shade or over-rich soil reduces blooming. Site in full sun and lean soil, and deadhead spent pompons to prolong the display.
Thinning mats under traffic
Like all Roman chamomile, double-flowered forms wear thin under heavy footfall. Reserve for light traffic and fill gaps with fresh divisions.
Powdery mildew and aphids
Still, humid air invites mildew and aphids on soft growth. Improve spacing and airflow, avoid wetting foliage, and rinse pests off promptly.
