How to grow Celeriac


CeleriacCeleriac, also known as celery root, is a root vegetable that is prised for its unique flavour and versatility in cooking. Growing celeriac can be a great addition to any home garden. Here is a comprehensive guide on how to grow Celeriac:

Choose the right location:

Celeriac grows best in full sun or partial shade and in fertile, well-drained soil. Avoid planting it in areas where water tends to pool as this can lead to root rot.

Prepare the soil:

Before planting, the soil should be worked to a depth of twelve to fifteen inches, and should be fertile, well-drained, and high in organic matter. If the soil is heavy clay, add sand and compost to improve drainage.

Planting: Celeriac seeds can be planted directly into the garden, or started indoors and then transplanted. If starting indoors, plant seeds 6-8 weeks before the last expected frost. If planting directly into the garden, plant seeds about 1/4 inch deep, 2-3 inches apart, in rows 2-3 feet apart.


Once the seedlings emerge, keep the soil consistently moist but not waterlogged. As the plants mature, reduce watering, but do not allow the soil to dry out completely.


Celeriac is a heavy feeder and will benefit from regular fertilisation. Apply a balanced, slow-release fertiliser every four to six weeks weeks, or compost with well-rotted manure to the soil before planting.


Mulching around the base of the plants will help conserve moisture and suppress weeds.


Thin seedlings to the final spacing of ten to twelve inches, taking care not to damage the roots of the remaining plants.


Staking may be necessary to prevent the plants from falling over, especially if they are grown in windy conditions.

Pest and disease control:

Celeriac is relatively resistant to pests and diseases, but it can be susceptible to aphids, slugs, and root maggots. Keep an eye out for these and treat promptly if necessary.


Celeriac is ready to harvest when the roots are about three to four inches inches in diameter. Carefully dig up the roots, taking care not to damage them. Harvest the roots when the soil is dry, and before the first hard frost.

Growing Celeriac is relatively easy and requires a bit of attention to soil preparation, water, and fertilisation. With proper care, you can enjoy a bountiful crop of this unique and tasty vegetable in your home garden.
