Troubleshooting
Spilanthes problems — and how to fix them
Spilanthes (Acmella oleracea) 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.
Frost sensitivity
As a tender tropical it is killed by the first frost. Grow as a summer annual, start under cover, and bring containers indoors or take cuttings before cold weather.
Wilting when dry
The succulent foliage collapses quickly in dry soil or heat. Keep soil evenly moist, mulch, and water containers frequently in summer.
Aphids and spider mites
Soft new growth attracts aphids, and hot dry air brings mites. Inspect tips and leaf undersides, rinse off pests, and maintain humidity.
Sparse flowering in shade
Insufficient light yields leggy growth with few buds. Site in full sun and pinch early to encourage a bushy, free-flowering habit.
Prevent spilanthes problems before they start
Most spilanthes issues are care-mismatch, not bad luck. Dial in the basics:
