How to Grow Celeriac (Celery Root) at Home

1. Choosing the Right Container: Opt for a deep container, at least 12 inches in depth, to accommodate the celeriac’s root growth. Ensure the container has adequate drainage holes to prevent waterlogging, which can lead to root rot.
2. Seed Starting: Begin by sowing celeriac seeds indoors about 10-12 weeks before the last frost date. Use a high-quality seed starting mix and plant seeds 1/4 inch deep in trays or pots. Keep the soil moist and provide ample light, either from a sunny window or grow lights, to encourage strong seedling growth.
3. Transplanting: Once the seedlings have grown and the risk of frost has passed, it’s time to move them into their containers. Harden off the plants by gradually exposing them to outdoor conditions over a week. This process reduces transplant shock and acclimates the seedlings to their new environment.
4. Soil and Fertilization: Fill your container with a rich, well-draining potting mix. Celeriac thrives in soil with a pH between 5.8 and 6.8. Incorporate a balanced, slow-release fertilizer into the mix before planting to support initial growth.
5. Planting: Space the celeriac seedlings about 12 inches apart in the container. This spacing gives each plant enough room to grow and prevents overcrowding.
6. Watering and Care: Maintain consistent soil moisture, as celeriac roots are prone to drying out. However, avoid overwatering. A mulch layer can help retain soil moisture and regulate temperature. Throughout the growing season, feed the plants with a liquid fertilizer every four weeks to ensure they receive all necessary nutrients.
7. Harvesting: Celeriac is ready to harvest approximately 14-16 weeks after planting, when the roots reach about 3-5 inches in diameter. The flavor of celeriac improves after a light frost, making late harvests particularly rewarding. Gently remove the root from the container, taking care not to damage it.
8. Storing: After harvesting, trim the foliage and roots, and store celeriac in a cool, humid place. Properly stored celeriac can last several months, providing you with a lasting supply of this flavorful vegetable.

Growing celeriac in containers is an accessible gardening project that yields delicious results. With patience and care, even novice gardeners can produce a bountiful crop of celeriac, ready to enhance a variety of dishes with its unique taste.
