Brassicas

Crop rotation is the practice of growing a series of dissimilar types of crops in the same space in sequential seasons to avoid the build-up of pathogens and pests that often occurs when one species is continuously cropped. Crop rotation also seeks to balance the fertility demands of various crops to avoid excessive depletion of soil nutrients.

For the purpose of planning crop rotation, plants are grouped by family (because they make similar demands and have similar susceptibilities).

Here are some examples of frequently grown crops, by plant family Cruciferae (HF) heavy nitrogen feeders.

 

Pigeons are serious pests of brassicas. Protect with frames of netting or fleece, and metal cages to keep them away from vulnerable crops.

Brassicas like fertile, well drained soil, but ensure moisture is maintained and the ground is firm.
