Because of Cabbage White Butterfly that is the bane of allotment holders all over the British Isles. The larva of this species can reach pest proportions, and decimate cabbages to the point that they become mere skeletons of their former selves in days.

Hoops and netting of some kind is required so the eggs can not be laid. I use scaffolding Debris netting and blue water pipe to form the hoop cages. White netting may be enviro mesh which is very expensive.

I save enviromesh for carrots to prevent carrot root fly.  Debris netting is fine to protect brassicas against cabbage butterfly and pigeons.   If you can find a scaffolding firm, they often give it away as they are only allowed to use it so many times.  You might have to sew up the odd hole though.

I use tulle (petticoat netting) its very fine and comes in 5' wide about £25 a roll
