How do I sow celery stalks under cover?

Celeriac is a demanding plant that requires special care when sowing. To sow it under cover, choose a deep container (around 10 cm) filled with good quality potting soil. Take care to maintain constant humidity by watering regularly, but without flooding the substrate.

Sowing can take place from February until March. It is important to maintain a constant temperature of between 15 and 20°C to encourage germination. Light is also essential, so it is advisable to place seedlings in a greenhouse or in front of a sunny window.

Be sure to transplant seedlings when they have 3 to 4 leaves to prevent them from growing too tightly. Choose a soil rich in organic matter and well drained to encourage the growth of celery stalks.

In short, to successfully sow celery stalks under cover, make sure you maintain constant humidity, the right temperature and sufficient light exposure. By following these tips, you'll soon be able to enjoy beautiful celery stalks.

How to plant celery stalks?

To grow celery stalks naturally, it is best to plant them in the ground in soil that is rich in organic matter and well drained. Choose a sunny or semi-shady spot to encourage the plant's growth. Celery stalks are generally planted in spring, once all risk of frost has passed. If you want to transplant plants, wait about 4 to 6 weeks after sowing before transplanting. Make sure you space the plants well, about 20-30 cm apart, to ensure they develop properly. Remember to hoe regularly to prevent competition from weeds and to water regularly without getting the leaves too wet to prevent disease. Avoid using chemical fertilisers; instead, use organic mulch to nourish the soil. Harvest your celery when the stalks are thick enough, generally from August onwards. Cut them back as and when you need to, pulling them out gently to avoid damaging the roots. Happy growing!
