Frequently Asked Questions

Why are my celery (Apium graveolens var. dulce) leaves yellowing and getting slimy, and what should I do?

Yellowing with limp, water-soaked or slimy patches is often caused by fungal rot and leaf spot in cool, wet conditions. Remove and discard infected plants or leaves, then improve airflow by thinning and watering at the soil line (not on the foliage). If rot keeps spreading, apply a labeled fungicide that includes celery/leaf spot/rot in its directions and stop any overhead watering until conditions dry out.

How often should I water sweet celery during its main growing phase to keep it crisp?

During the main growth phase (roughly weeks after emergence until harvest), keep the soil consistently evenly moist—about 1 to 1.5 inches (2.5–4 cm) of water per week, adjusting for heat and container vs. ground. Water deeply, then let the top 1 inch (2–3 cm) dry slightly before watering again to avoid waterlogging, which encourages rot. Mulch lightly to reduce moisture swings, because irregular watering can lead to tough stalks and poor crunch.

How can I tell when sweet celery is ready to harvest at about 85 days?

Harvest when stalks are firm, fully developed, and reach their expected thickness for your variety, with leaves held upright and bright green. You should be able to pull or cut outer stalks cleanly without them collapsing or feeling hollow at the base. For best flavor, harvest before prolonged hot weather and when the plant has built a solid, dense crown.

Sowing Tips

Transplant Conditions

Wait until soil reaches 40°F and nights stay above 32°F before moving outdoors. Harden off for 7 days first.

Expert Note

Start indoors warm and transplant only after soil is at least 60°F, since even “early” heat-tolerant types still need warm ground to avoid cold-stunt.
