Troubleshooting
Endive problems — and how to fix them
Endive (Cichorium endivia) 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.
Bitter taste / bolting
Heat and long days trigger bolting and intensely bitter leaves. Sow in late summer for autumn harvest and blanch hearts 2–3 weeks before cutting by tying outer leaves over the centre.
Tip burn
Calcium deficiency under stress (drought or irregular watering) causes brown leaf margins. Maintain even soil moisture and avoid over-fertilising with nitrogen.
Slugs and snails
Young seedlings are highly vulnerable. Use copper barrier tape, iron phosphate pellets, or trap with beer traps; inspect plants at night during wet weather.
Prevent endive problems before they start
Most endive issues are care-mismatch, not bad luck. Dial in the basics:
