How to Successfully Grow Celeriac Seeds in the UK

Celeriac, also known as celery root, is a versatile and delicious vegetable that can be grown from seeds in the UK. With its unique flavor and numerous health benefits, celeriac is a great addition to any garden. In this article, we will guide you through the process of successfully growing celeriac seeds in the UK.

Choosing the Right Seeds

To start your celeriac growing journey, it is important to choose the right seeds. Look for reputable seed suppliers that offer celeriac seeds specifically suited for UK growing conditions. Opt for certified organic seeds whenever possible to ensure the best quality and to support sustainable farming practices.

Preparing the Soil

Celeriac thrives in well-drained, fertile soil. Before sowing the seeds, prepare the soil by removing any weeds and incorporating organic matter such as compost or well-rotted manure. This will improve the soil structure and provide essential nutrients for the growing plants.

Sowing the Seeds

Celeriac seeds are best sown indoors in early spring, around February or March. Fill seed trays or pots with a good quality seed compost and lightly firm the surface. Sow the seeds thinly and cover them with a thin layer of compost or vermiculite. Water gently and place the trays in a warm location, such as a greenhouse or a sunny windowsill.

Transplanting Seedlings

Once the seedlings have developed their first true leaves and are large enough to handle, they can be transplanted into individual pots or modules. This is usually done when the seedlings are about 5-7cm tall. Handle the seedlings carefully to avoid damaging the delicate roots, and plant them at the same depth as they were in the seed trays.

Planting in the Garden

After the last frost date in your area, usually around mid to late May, the celeriac seedlings can be planted out in the garden. Choose a sunny or partially shaded spot with well-drained soil. Space the plants about 30cm apart, allowing enough room for the roots to develop. Water the plants thoroughly after planting.

Caring for Celeriac Plants

Celeriac plants require consistent moisture throughout the growing season. Water them regularly, especially during dry spells, to prevent the roots from drying out. Mulching around the plants with organic matter will help retain moisture and suppress weed growth.

Feeding and Harvesting

To encourage healthy growth, feed the celeriac plants every two weeks with a balanced organic fertilizer. As the plants mature, remove any side shoots that develop to focus the plant’s energy on producing a larger root.

Celeriac is typically ready for harvest in late autumn or early winter, around 90-120 days after transplanting. Gently lift the plants from the ground, being careful not to damage the roots. Trim off the leaves and store the roots in a cool, dark place for later use.


Growing celeriac seeds in the UK can be a rewarding experience. By choosing the right seeds, preparing the soil, sowing and transplanting the seedlings correctly, and providing proper care throughout the growing season, you can enjoy a bountiful harvest of this unique and flavorful vegetable. Remember to water regularly, feed the plants, and harvest at the right time for the best results. Happy gardening!
