Description

(Apium graveolens) 100 days. Thick, crisp, medium-dark green stalks reach a foot or more when well grown; of high quality. The improved variety we sell, Utah Tall 52/70, was introduced in 1953.

Growing Tips: Celery thrives in rich, loamy soil with plenty of organic matter to retain moisture. Ensure the soil is well-draining and has a pH between 5.8 and 6.8. Water regularly to avoid a stringy and bitter taste. Also, make sure that the plant receives at least 6 hours of sunlight daily.

When to Grow

Start seeds indoors 8-12 weeks before the last frost date. Celery needs a long growing season, typically about 100 days to mature. Transplant the seedlings outdoors only after night temperatures stay reliably above 55 F, usually about 2 weeks after the last frost, to avoid cold-induced bolting. The ideal temperature for Utah Tall celery is 70-75 F. If you're not sure how to find your first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Starting Seeds Indoors: Soak seeds overnight to speed up germination. Sow seeds in flats or trays 1/8 inch deep, gently pressing into the soil. Keep the soil moist. Transplant seedlings when they are about 6 inches tall.

Transplanting: Harden off seedlings before transplanting them into the garden. Space plants about 10 inches apart in rows 2-3 feet apart. Mulch around the plants to retain moisture and regulate soil temperature.

How to Grow

Celery grows best in temperatures between 70-75 F. It is a cool-weather crop and can bolt if exposed to temperatures below 55 F when young​. Make sure that the planting site receives full sun to partial shade. Incorporate compost into the soil before planting and side-dress with compost or a balanced fertilizer every few weeks​. To conserve moisture and control weeds, you can use mulch.
