Troubleshooting
Chicory problems — and how to fix them
Chicory (Cichorium intybus) 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.
Bolting in heat
Warm temperatures and long days trigger flowering and make leaves unpalatably bitter. Time sowings for cool seasons and harvest before plants bolt; radicchio varieties benefit from autumn temperature drop for head formation.
Crown rot / damping off
Caused by Pythium and Botrytis in waterlogged or poorly ventilated conditions. Ensure sharp drainage and avoid overhead watering. Rotate crops annually to break disease cycles.
Cutworm damage
Larvae sever stems at soil level overnight. Use physical collars around transplant stems, cultivate soil to expose pupae, or apply beneficial nematodes as a preventative drench.
Prevent chicory problems before they start
Most chicory issues are care-mismatch, not bad luck. Dial in the basics:
