How to Grow Celery Seeds

Overview

Growing celery in your vegetable garden allows you to harvest the crisp, green stalks for use in soups, salads and other dishes. Celery can be a finicky vegetable to grow, as it requires warm soil and plenty of soil nutrition to thrive. While celery is often purchased as a seedling, growing the celery from seed is possible if you have long, warm summers in your area. Seed can also be started inside eight to 10 weeks before the last spring frost date and later transplanted to the garden once frost danger has passed.

Step 1

Fill individual seed pots with moist potting mix. Sow three to five celery seeds on the surface of the soil then cover with ¼ inch of soil.

Step 2

Mist the surface of the potting mix with water to moisten it. Cover the top of the pots with plastic wrap and place in a 70 Fahrenheit room to germinate, which takes approximately seven to 14 days.

Step 3

Remove the plastic wrap from the pots once celery sprouts appear. Move the seed pots to a bright, sunny window and water as necessary to keep the soil moist but not soggy.

Step 4

Thin each pot to one seedling once the celery plants are three to four inches tall and have produced their second set of leaves. Cut off the weaker seedlings at the soil level with a small pair of scissors and leave the strongest seedling in the pot.

Step 5

Prepare a well-draining, full-sun garden bed once daytime temperatures are at least 55 Fahrenheit and there is no more danger of frost. Lay a two-inch layer of compost over the bed then apply two pounds of 16-16-8 analysis fertilizer over every 100 square feet of bed. Till the compost and fertilizer into the top six to eight inches of soil.

Step 6

Plant the celery seedlings 12 inches apart in rows that are spaced one foot apart. Plant the celery at the same depth it is at in its seed pot. Water thoroughly after planting then keep the bed moist but not soggy throughout summer, providing about one to two inches of water a week.

Tips and Warnings

  • Frost kills celery. Cover plants if a late-season frost is predicted in spring.
