How to sow celeriac successfully under cover?

To grow celeriac successfully, we recommend sowing under cover in early spring, around March. Use individual cups to sow the seeds, spacing them about 1 cm apart. Make sure the soil is well drained and rich in organic matter. Water regularly but sparingly to maintain constant humidity.

Place your cups in a warm, bright place, but avoid direct sunlight. Make sure the temperature is around 20°C to encourage germination. Once the plants are well developed, transplant them into the open ground once there is no risk of frost.

Be careful not to over-water to prevent root rot. It is also advisable to mulch the soil to retain moisture and limit weeds. Celeriac needs fresh, humus-rich soil, rich in compost. Avoid chemical fertilisers for a natural, more environmentally-friendly crop.

How do I sow celeriac outdoors?

For successful outdoor sowing of celeriac, it is advisable to do so in spring, once any risk of frost has passed. Prepare the soil by clearing it of all weeds and working it deeply so that it is well aerated.

The recommended sowing distance is around 30 cm between each plant. Sow the seeds about 1 cm deep, spacing them a few centimetres apart. Be sure to water regularly to keep the soil cool until the seeds emerge.

Once the plants have 3 to 4 leaves, thin them out, keeping only the most vigorous, making sure to leave a distance of about 20 cm between each plant.

It's important to keep an eye on pests and diseases, particularly celery rust. In the event of an attack, favour biological control methods to protect your plants.

How do I plant celeriac?

To grow celeriac, it's important to choose a sunny position and cool soil rich in organic matter. The ideal time to plant celeriac in the ground is in spring, once there is no risk of frost. Prepare the soil by spading it deeply and incorporating compost to improve its structure and fertility.

If you opt for sowing, sow the seeds 1 cm deep, spacing them 20 cm apart. For a quicker harvest, you can also transplant celeriac plants previously grown in pots. Water regularly but avoid wetting the leaves to prevent disease.

Celeriac needs regular watering to develop properly, so make sure you keep the soil moist but not excessively so. To prevent pests, mulch the soil around the plants. Harvest celeriac when the roots have reached a sufficient size, usually 5 to 7 months after sowing.

How do I harvest celeriac?

To harvest celeriac, we recommend waiting until late summer or early autumn, when the roots have reached a sufficient size. To harvest, simply pull the plant carefully by grasping the base of the stalk and gently lifting it from the ground. It is important not to damage the roots when harvesting to ensure better preservation.

Once harvested, celeriac can be stored for up to several months in a cool, ventilated place, such as a cellar. It's important to remove the leaves and keep the roots in a dark place to prevent them from sprouting.

By following these simple tips, you'll be able to enjoy your celeriac harvest well into autumn and winter, adding a touch of freshness to your dishes. And don't forget, celeriac is also an excellent source of vitamins and minerals for your health!
