Troubleshooting
Celery problems — and how to fix them
Celery (Apium graveolens var. dulce) 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.
Tip burn (brown leaf margins)
A calcium deficiency symptom caused by irregular watering or rapid heat-driven growth. Maintain even soil moisture, avoid excessive nitrogen, and ensure calcium is available in the soil (pH above 6.0).
Celery leaf miner (Euleia heraclei)
Larvae tunnel within leaves, causing pale blotches and wilting. Remove and destroy affected leaves promptly; use fine insect mesh over plants from sowing. More prevalent in UK gardens than the US.
Bolting
Exposure to temperatures below 10°C for 10+ consecutive days triggers premature flowering, making stalks tough and bitter. Plant out only after soil has warmed and protect young transplants from cold snaps with fleece.
