Depending on the growth of the varieties, celery needs a plant spacing of 50 cm x 40 cm to 40 cm x 40 cm.
A narrow stand width has a negative effect on the yield. Even with the plant spacing of 50cm x 40cm, choose 40cm as the row spacing, so that the outer rows are 20 cm away from the edge of the bed. This space will be needed later when bleaching. Celery must be protected from late frosts, because otherwise bolts will form, that are not usable. Therefore, the planting takes place only in the last days of May. As soon as there is danger of night frost, covered with a plant protection hood.
