Troubleshooting
Skirret problems — and how to fix them
Skirret (Sium sisarum) 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.
Woody root core
Older roots and drought-grown plants develop a tough, stringy central core. Lift first- or second-year roots after frost and keep soil moist for tender flesh.
Fiddly harvest and cleaning
The fingered, branching roots trap soil and snap easily. Lift carefully with a fork and soak before scrubbing to clean the crevices.
Drying out
As a wetland-edge plant it sulks and produces poor roots in dry soil. Mulch heavily and water through dry spells to keep the crown damp.
Carrot fly and aphids
Being an umbellifer, it can attract carrot fly to the roots and aphids to the foliage. Use mesh barriers and rotate away from other carrot-family crops.
Prevent skirret problems before they start
Most skirret issues are care-mismatch, not bad luck. Dial in the basics:
