Troubleshooting
Feverfew problems — and how to fix them
Feverfew (Tanacetum parthenium) 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.
Prolific self-seeding
Sets abundant seed and can pop up everywhere; deadhead spent flowers to control spread if you want it contained.
Aphids on new growth
Soft shoots attract aphids; dislodge with a water spray or tolerate them for the beneficial insects feverfew attracts.
Short-lived crowns
Plants often decline after two or three years; allow some self-seeding or take cuttings to maintain the planting.
Contact dermatitis
Handling foliage and sap can cause skin rash and sensitisation in some people; wear gloves when cutting or weeding.

Most feverfew issues are care-mismatch, not bad luck. Dial in the basics:
