Description

Celery root forms a strong, flavorful bulb that is essential as a vegetable for soups, purées, or raw salads. It has a long growing period and requires a nutrient-rich, evenly moist soil to produce large bulbs. The foliage can be used like that of celery stalks.

Care instructions

Sow in February on a windowsill and transplant seedlings flat in mid-May (week 20) so that the bulb is above the soil surface. Water abundantly and evenly, because dryness keeps the bulbs small and hollow. In late summer remove the lower leaves and the side roots at the bulb edge, then the bulbs become round and smooth; harvest before the first hard frost.
