Apium graveolens

Apium graveolens is commonly known as celery, and it’s a cool-season biennial vegetable. Here’s a concise guide on how to grow celery:

1. Climate: Celery prefers cool climates. It’s often grown as a spring or fall crop in temperate regions. In warmer climates, it can be cultivated as a winter crop.

2. Sunlight: Plant celery in a location that receives full sunlight, especially in cooler climates. In warmer regions, partial shade might be beneficial to protect it from intense sun.

3. Soil: Choose well-draining, fertile soil rich in organic matter. Celery prefers a slightly acidic to neutral pH (6.0-7.0).

4. Planting: Start celery seeds indoors 10-12 weeks before the last expected frost date. Transplant seedlings when they are about 2 inches tall and have at least two true leaves. Space plants about 8-10 inches apart in rows with 24-36 inches between rows.

5. Watering: Celery requires consistently moist soil. Water regularly, providing 1-1.5 inches of water per week. Use drip irrigation or soaker hoses to keep the foliage dry and reduce the risk of diseases.

6. Fertilization: Fertilize with a balanced, all-purpose fertilizer at planting. Side-dress with nitrogen-rich fertilizer during the growing season to promote leafy growth.

7. Mulching: Apply a layer of mulch around the celery plants to help retain soil moisture, suppress weeds, and regulate soil temperature.

8. Hilling: As celery plants grow, gradually hill soil around the base of the plants to blanch the stalks. This process helps reduce bitterness and improves the appearance of the stalks.

9. Temperature: Celery performs best in temperatures between 60-70°F (15-21°C). In hot weather, provide shade or use varieties that are more heat-tolerant.

10. Pest and Disease Control: Monitor for pests such as aphids or caterpillars. Control with insecticidal soap or neem oil if necessary. Keep an eye out for common celery diseases like early blight.

11. Harvesting: Celery is ready for harvest when the stalks are large and crisp. Start harvesting outer stalks when they reach the desired size, or harvest the entire plant at once.

12. Storage: For long-term storage, celery can be blanched and frozen. Store fresh celery in the refrigerator for up to two weeks.

Remember that celery cultivation might vary based on the specific variety you’re growing and your local climate conditions. Always refer to any specific care instructions provided by the seed supplier or nursery.
