Organic celeriac Roem van Zwijndrecht forms a tasty tuber with a diameter of about ten cm and is smaller than the most common celeriac.
Celeriac has a long growing period and it is precisely in the final stage, when the growth of the tuber is to take place, that the plant must have access to sufficient nutrients.

Celeriac has a long growing period and it is precisely in the final stage, when the growth of the tuber is to take place, that the plant must have access to sufficient nutrients.
This requires a strong, preferably humous soil. A scoop of compost in the planting hole works very well. Sow in April in a container in a warm place (approx. 20°C). Prick out in pots after approx. 1 month or temporarily in a greenhouse or flat box, then plant in the open ground. Plant out in the garden from the second half of May at 50 x 40 cm. Put up at the end of October, shake off some soil, cut off the outer leaves and dig in together, the tuber just below the ground. Cover during frost. Frost-free ensilage is also possible, then remove all the leaves.
