Growing Celeriac: The Knobby Root Worth The Effort

Celeriac, also known as celery root, is a versatile and underappreciated vegetable.

Why Choose Celeriac?

Celeriac has a unique, nutty flavor and smooth texture when cooked.

It's incredibly nutritious and stores well through winter.

Growing celeriac can be immensely rewarding with the right care and patience.

Studies show that celeriac is rich in vitamin C, K, and essential minerals like phosphorus and potassium.

Preparing the Soil

Celeriac thrives in rich, well-drained soil.

In my garden, I mix in 4-6 inches of compost to improve soil quality.

A pH range of 6.0 to 7.0 works best for optimal growth.

Planting Celeriac

Start celeriac seeds indoors 8-10 weeks before the last frost date.

Sow seeds in seed trays and keep them moist but not waterlogged.

  1. Transplant seedlings outside when they have at least 4-5 leaves.
  2. Space them 12-18 inches apart to allow room for bulb growth.
The key to robust celeriac is consistent moisture throughout the growing season.

Sowing Tips

Plant celeriac in an area that receives full sun for at least 6 hours daily.

If space is limited, consider using deep containers or raised beds.

In my experience, mulching around the base helps retain moisture and control weeds.

Care and Maintenance

Celeriac needs regular watering, especially during dry spells.

Avoid waterlogging, as this can lead to root rot.

Once a month, feed celeriac with a balanced, organic fertilizer.

Trim foliage as needed to direct energy to the root.

I like to side-dress my celeriac with compost mid-season for an extra nutrient boost.

Harvesting Celeriac

Wait until late fall to harvest; this ensures the bulbs reach full size.

Look for roots about 3-4 inches in diameter.

  1. Use a garden fork to gently lift the roots out of the soil.
  2. Trim away excess roots and foliage, leaving about an inch of the stalk.

Store harvested celeriac in a cool, dark place, and it will keep for several months.

Get creative in the kitchen!

Roast, mash, or puree celeriac for a delightful addition to your meals.
