Sowing Tips

Soil Temperature

Direct sow or transplant when soil at planting depth holds 40°F for reliable germination and early growth.

Expert Note

Start seedlings in a cool indoor window (they dislike heat early), then transplant only after nights are consistently mild and keep soil evenly moist for crisp, sweet stalks.

Crop Dates

Growing note: In frost-free Zone 13b, grow this cool-season crop during the cooler dry season (October–February).

Frequently Asked Questions

What pest or disease commonly affects sweet celery (Apium graveolens var. dulce), and how can I control it?
Watch for celery leaf spot and early blight-like foliage spots, which show up as dark lesions on leaves that spread during humid weather. Remove infected leaves early, improve airflow by thinning plants, and avoid wetting the foliage when you water. If issues persist, use an approved copper-based fungicide label specifically for celery/leaf spot and reapply according to label directions.
How often should I water sweet celery during the main growing phase?
Keep the soil consistently evenly moist from transplanting through active leaf growth—celery (Apium graveolens) depends on steady moisture to form crisp stems. Water deeply about 2–3 times per week depending on heat and rainfall, aiming for soil that stays damp 1–2 inches down without pooling. Mulch around plants to reduce drying, and avoid letting the soil swing from dry to soggy, which can worsen bitterness and tip/stem issues.
How do I tell when green/sweet celery is ready to harvest?
Harvest when plants are about 8–10 inches tall with thick, crisp ribs and a firm “snap” when you gently bend a stalk. For Apium graveolens var. dulce, start checking around 90 days from sowing/transplanting—use the days-to-maturity as a guideline, but base harvest on stem firmness rather than only the calendar. Cut individual stalks from the outside inward, or harvest the whole plant when the center stalks are similarly thick and well-developed.
