Ivydene Gardens Companion Planting:
Katie Thear's 4-year Rotation Vegetable Garden

In order to avoid planting crops on the same ground 2 years running and thus making pest problems more likely, I have decided on a 4-year crop rotation of:-
  potatoes,
  legumes,
  brassicas and
  roots
in Veg Areas 2, 3, 4 and 5. Within this basic system, I would intercrop appropriate companion plants as listed in the Companion Plant A-Z Table.
Unfortunately, there are discrepancies between this crop rotation and companion planting:-

Broad beans are companions of cabbages, but the rotation would have the former in a legume bed and the latter in a brassica bed.

The basic four-crop rotation will be followed and any companion plants introduced will be annuals in order to simplify bed clearance at the end of the season. Perennial crops and perennial herbs will be planted outside the rotation system in Veg Areas 6 and 8, and 'weed' plants such as yarrow will be grown in solitary confinement in Veg Area 8.

The following is a copy of Katie Thear's 4-year rotation in her vegetable garden plan, which solves some of these contradictions:-
