How to Grow Celeriac: Tips for a Successful Harvest

When it comes to growing vegetables, celeriac is not one that usually comes to mind. However, this root crop is a delicious addition to any dish and is packed with nutrients. While it may seem challenging to grow, with the right steps and care, you can have a successful harvest of celeriac. In this article, we will guide you through the process of how to grow celeriac.

1. Choosing the Right Location

The first step in growing celeriac is selecting the right location. The ideal spot is an area with well-draining soil that is rich in organic matter. Choose a spot with full sun exposure, although celeriac can tolerate partial shade. Make sure the location is not too windy or exposed as celeriac plants can be sensitive to strong winds.

Once you have chosen the location, prepare the soil by removing any weeds and adding compost or well-rotted manure. Deeply cultivate the soil to loosen it and create a planting bed with a depth of at least 30cm.

2. Starting Seeds Indoors

Celeriac seeds can take up to three weeks to germinate, so starting them indoors can help speed up the process. Start seeds six to eight weeks before the last frost date in your area. Fill seed trays with potting soil and sprinkle the seeds on top, pressing them into the soil gently. Cover the tray with plastic or a dome to retain moisture and warmth, and place it in a warm, bright spot.

Once the seeds have sprouted, remove the cover and provide ample light. Keep the soil moist but not waterlogged, and fertilize with a balanced fertilizer every two weeks. When seedlings have developed their second set of leaves, transplant them to larger pots until they are ready to be planted outdoors.

3. Planting Celeriac Outdoors

When the seedlings are 15cm tall and the danger of frost has passed, they are ready to be planted outdoors. Dig a hole in the prepared planting bed and carefully transplant each seedling, making sure the crown of the plant sits just above the soil surface. Space the plants 30cm apart in rows that are 40cm apart.

Water the seedlings thoroughly after transplanting, and continue to keep them moist throughout the growing season. Mulch around the plants to retain moisture and suppress weeds. Fertilize the plants every four to six weeks with a nitrogen-rich fertilizer.

4. Care and Maintenance

Celeriac requires consistent watering to develop healthy roots. Water deeply once a week, or more often during hot, dry weather. Monitor the plants for signs of pests or disease, and treat them promptly if necessary.

As the plants grow, gradually hill the soil up around the base of the stem to prevent it from becoming woody. This process, called blanching, will also help the plant develop a round, smooth shape.

5. Harvesting Celeriac

Celeriac plants take about five months to mature. Harvesting should occur when the roots are around 10cm in diameter, usually in late autumn. Carefully dig up the plants with a garden fork, taking care not to damage the roots. Cut off the leaves and store the roots in a cool, dark place, such as a cellar or refrigerator.

Celeriac can be used in a variety of dishes, including soups, stews, and salads. It has a distinct flavor that is similar to celery but with a nutty, earthy undertone. Enjoy the fruits of your labor by incorporating this nutritious vegetable into your meals.
