Frequently Asked Questions

Why are my sweet celery plants developing dark, water-soaked stems or leaves, and what can I do about it?

This is often early blight/leaf spot complex or bacterial soft rots common in Apiaceae when foliage stays wet and air flow is poor. Remove affected leaves, avoid overhead watering, and water at the soil line in the morning so leaves dry quickly. Keep plants spaced for airflow and consider a labeled copper-based fungicide if spots are spreading.

How often should I water sweet celery (Apium graveolens var. dulce) during its main growth to prevent problems?

During active growth, keep the soil consistently moist—aim for evenly damp not soggy—because celery roots dry out quickly. Water about 1–2 times per week depending on heat, with enough depth to wet the root zone; check by feeling the soil 1–2 inches down. If the soil dries between waterings, celery can become stringy and the plant may bolt or stall.

How do I tell when sweet celery is ready to harvest at about 75 days?

Harvest when stalks are firm, crisp, and reach their expected size for your variety, typically around day 75. Look for full-height stalks with tight, upright centers and leaves that are green and healthy rather than floppy. For best eating quality, harvest in the morning and cut stalks at the base or harvest outer stalks first to keep the plant producing.

Fragrant, crisp stalks with a clean, bright snap—Concurrency celery grows into a dense, upright clump that feels as refreshing as it tastes. The flavor is pleasantly mild and distinctly celery-forward, with a tender, stringless texture that stays crisp from garden to table. Ideal for fresh use and for stir-ins, soups, and savory sauces where its aromatic character shines.

Sowing Tips

Transplant Conditions

Wait until soil reaches 45°F and nights stay above 35°F before moving outdoors. Harden off for 7 days first.

Expert Note

Keep celery evenly moist and avoid letting seedlings dry out—consistent moisture is key to preventing bitterness and weak stalks.
