When to plant: Celery likes a long, mild, cool season — plant from late summer through autumn in warm areas, or spring in cooler ones. Our free planting calendar shows the right months for your postcode.
Growing them in a raised bed: Plant into very rich, moisture-holding mix. The number-one rule is never let it dry out — celery grown dry turns stringy and bitter. A drip watering system takes the worry out of it.
Watering and feeding: Keep the mix constantly moist and feed regularly — celery is one of the thirstiest, hungriest crops you'll grow. Mulch well to hold the moisture.
Common pests: keep an eye out for aphids, slugs and snails and caterpillars. Most are easily managed — see our safe pest guide.
Common diseases: the main ones are leaf spot and downy mildew. Good airflow, morning watering and steady moisture prevent most.
Companion plants: It grows happily near leeks, and the two are good kitchen partners too. See our companion planting guide.
Harvest and storage: Harvest outer stalks as you need them and let the plant grow on, or cut the whole bunch at the base. Use it fresh.
