The required planting distance depends primarily on the variety used.
A distance of 30cm x 40cm to 40cm x 40cm is sufficient under glass and foil. In the field, choose a space of for early varieties 40 cm x 40 cm to 50 cm x 40 cm, while mid-early varieties 50 cm x 50 need cm. The very vigorous late varieties require a planting width of 60cm x60cm. The early outdoor cauliflower should not be planted too deep, because during this time the deep heating in the soil is still too low. When planting shallowly, the roots come into the already better warmed top layer of soil, which has a positive effect on growth. So that the plants are not pushed over later by the wind, you heap the cauliflower about 2 weeks after planting. In this case, however, no intermediate culture succeeds.
