Sunlight: Choose a location that receives full sun for at least 6-8 hours a day. In warmer climates, partial shade during the hottest part of the day can help prevent bolting.

Soil: Prefers well-drained, fertile soil with a pH between 6.0 and 7.0. Celery thrives in soil rich in organic matter, so amend the soil with plenty of compost or well-rotted manure before planting. The soil should be kept consistently moist but not waterlogged.

When to Plant: Celery has a long growing season and is typically started indoors 10-12 weeks before the last expected frost date. In cooler climates, seeds should be started indoors and transplanted outside after the danger of frost has passed. In warmer climates, seeds can be sown directly in the garden in early spring or late summer for a fall harvest.

Starting Indoors: Sow seeds on the surface of the soil and lightly press them down. Celery seeds need light to germinate, so do not cover them with soil. Keep the soil moist and maintain a temperature of 70-75°F (21-24°C) for optimal germination. Seeds typically take 2-3 weeks to germinate.

Transplanting: Transplant seedlings outdoors when they are 4-6 inches tall and the danger of frost has passed. Space plants 8-10 inches apart in rows 24-30 inches apart. Harden off seedlings before transplanting by gradually exposing them to outdoor conditions over a week.

Watering: Celery requires consistent moisture to develop tender, crisp stalks. Water regularly, ensuring the soil stays evenly moist but not waterlogged. Mulching around the plants can help retain moisture and keep the soil cool.

Fertilization: Celery is a heavy feeder and benefits from regular fertilization. Apply a balanced fertilizer or compost at planting time. Side-dress with compost or a balanced fertilizer every 3-4 weeks during the growing season to support healthy growth.

Mulching and Weeding: Apply a thick layer of mulch around the plants to retain soil moisture, suppress weeds, and keep the soil temperature consistent. Hand-pull weeds carefully to avoid disturbing the shallow roots of the celery.

Blanching (Optional): Blanching involves covering the stalks to protect them from the sun, which results in a milder flavor and paler color. To blanch celery, wrap the stalks with newspaper, cardboard, or use commercial celery collars about 2-3 weeks before harvest. This step is optional and depends on your flavor preference.

Pest and Disease Management: Celery can be susceptible to pests such as aphids, slugs, and celery leafminers. Use organic pest control methods like neem oil, insecticidal soap, or hand-picking to manage infestations. Practice crop rotation and ensure good air circulation to prevent fungal diseases like early blight and leaf spot.

When to Harvest: Tendercrisp Celery is typically ready to harvest 85-120 days after transplanting, depending on growing conditions. Harvest when the stalks are about 12-18 inches tall and have thickened to a usable size. For the best flavor, harvest before the plants bolt (go to seed).

How to Harvest: Use a sharp knife to cut the entire plant at the base, just below the soil level. Alternatively, you can harvest individual stalks from the outside of the plant as needed, allowing the inner stalks to continue growing.
