Vegetable garden: growing cauliflower

Seedlings start in February and continue until September, in open ground or nursery depending on the season.  There are many varieties of cauliflower:
– The spring variety: sown outdoors from late summer to early autumn.
The summer variety: sown in nursery as of February.
The winter variety: sown in May and June.
Harvesting is all year-round according to the variety, and done once the cauliflower is compact.

Many pests can attack the leaves: the flea beetle, the larvae of diamond back and cabbage maggot (these are insects that eat the leaves and thus cause damages: appearance of small holes in the leaves). These pests may affect the optimal growth of the plant. Cauliflower is a vegetable but also a flower.
