Celery Growing Guide

Celery, a popular and versatile vegetable, has specific growing needs, and when they are met, you will get the best yields.

Our Tall Utah is a very disease resistant, cool season variety, with stringless, thick stalks. It's one of the finest and less particular varieties to grow, and is recommended for Northern climates.

One of the greatest rewards of growing celery is the tasty soups and salads it will enhance.

Soil and Fertilizing
Celery requires a rich, fertile soil, high in organic matter, and a minimum soil temperature of 60° Fahrenheit. The pH should between 6.0 and 6.8. It can tolerate damp soil, as it was originally a wetland plant. It's best to have your soil tested before planting, to find out what nutrients and pH levels are needed for your plants. For a thorough soil test, visit an Agricultural Experiment Station in your area (scientific research center) or consult your local county extension agent (also known as a Land Grant University).

Use a clean organic mulch to suppress weeds and retain moisture in the soil, as celery doesn't manage heat well, and its small root system can't compete with weeds.

Planting
Celery requires a long growing season, so you need to plant seeds indoors 12 weeks before last frost. They grow best when nighttime temperatures are around 50° Fahrenheit, and average daytime temperatures stay between 60° and 70° Fahrenheit.

Before transplanting seedlings, harden them off for 7-10 days by reducing water. Transplant 6-12 inches apart in rows 24 inches apart.

Watering
Celery needs plenty of moisture, so water regularly, ensuring it gets 1-2 inches each week during growing season.

Harvesting / Storage
You can harvest individual stalks when they are at least 6 inches long from the soil line to the first node. Plants can be harvested in their entirety when they're three inches across at the base. The best celery is compact rather than open at the center.

Refrigerate harvested celery as soon as possible. Keep stored celery at a humidity near 95%, and a temperature between 31° and 32° Fahrenheit.

For additional information specific to your growing area, please consult your local county extension office.
