Botanical Name: Apium graveolens
Type and Use: Biennial, grown as an annual, edible stalk and leaves
Location: Sun to partial shade. Morning sun and afternoon shade.
Planting Dates: For fall, 14-16 weeks before the first average frost. Use transplants for the home garden. Use 8-12 week old transplants.
Planting Method: Seed. Sow seed in late winter in flats in organic potting soil no more than ¼ inch deep. Move seedlings to 4 inch pots when 1 inch tall.
Seed Emergence: 12-20 days. Up to 3 weeks at 60-70°
Harvest Time: 90-120 days
Height: 12-15 inches
Spread: 8-10 inches
Final Spacing: 8-12 inches for double rows, rows 10-14 inches apart, 6-12 inches between plants. A 6-11 inch spacing is considered the most efficient.
Growth Habits: Upright, leafy vegetable with edible stalks. Hard to grow.
Culture: Needs cool temperatures for success. Celery is cold hardy but will freeze during harsh winters. Avoid moisture stress to young plants. When the plants are about 8 inches, loosely tie the stalks together for compact and upright growth. Use lots of Texas greensand, lava sand, soft rock phosphate, and compost.
Troubles and Solutions: Not easy to grow. Blackheart is a calcium deficiency that is treated with soft rock phosphate at 20-30 lbs. In the soil. Boron deficiency is common in a chemical program but not in an organic program where the soil is healthy. Bitter taste results from high temperature and lack of trace minerals in the soil.
Harvest and Storage: Harvest 30-40 stalks per 10’ of row and store in the refrigerator.
Notes: Celeriac is one half celery and one half lettuce. Also called knob celery.
