Celery & Celeriac
110 days. Apium graveolens var. rapaceum Celeriac is a type of celery grown for its baseball sized, nutty-flavored roots. This European strain is an excellent early-maturing variety. Selected from our trials for its uniform, nearly fiberless white, 3-5 inch diameter roots and good productivity. Stores well. Peel, cut into bite-sized pieces, and saute. Delicious!

Apium graveolens var. dulce Long known as an unsurpassable diet food, celery stalks contain 94% water and only 15 calories in 2 medium stalks. Surprisingly, celery contains about a dozen antioxidants as well as about 37% daily value of vitamin K in 1 cup. Enjoy it in 3 forms: its leaf, the stalks, and the swollen rootstock we know as celeriac.
CULTURE: The most successful crops are grown for fall harvest rather than mid-summer harvest. Weather fluctuations and cold nights cause celery to bolt. Sow in sterile seedling mix indoors February through April. Keep soil moist. When raising transplants soil temperature is vital to success. Transplant in rows 18-24 inches apart when the weather is warm enough for peppers and melons. Celery is one of the heaviest feeding plants grown in the garden. Apply 1 1/2-2 cups of our complete fertilizer into the soil per 5 row feet to provide adequate nutrition. Keep well watered. Bolting is the result of young plants being exposed to nighttime air temperatures below 55°F for a week or more. Direct sowing is not recommended.
DISEASE: Good preventive measures include crop rotation, adequate water supply, and aphid control.
INSECTS/PESTS: The larva of the carrot fly is an occasional celery pest. Mature larva are 3/8 inch long, straw-colored, and wiry. Worms burrow into the heart and kill or stunt the plant. Crop row covers such as Reemay, Grow Guard 20, or Summer Insect Barrier are very effective deterrents.
HARVEST: In a normal maritime Northwest winter many varieties of celery will stand in the garden until spring, allowing light pickings for soups and salad. Chopping off the entire head is not advisable. Instead, pick individual stalks as needed. In spring, the unopened flowers and the tender stalks below them are particularly good tasting.
SEED SPECS: Minimum germination standard: 65%. Days to maturity calculated from transplant date; add 60 days if direct seeding. Usual seed life: 3 years.
