Divide your growing space into at least 4 areas, identify the crops you want to grow and then keep plants of the same type together in one area. Change the type of plants grown in each area every year and try not to grow plants from the same type in the same place for 3 years (i.e. only replant in the same place in the 4th year).
Group your plants into the following categories:
Carrots, Beetroot, Chicory, Artichoke (Jerusalem), Parsnips, Potatoes and Salsify.
Brussels Sprouts, Broccoli, Cabbage, Cauliflower, Kale, Kohl Rabi, Radish, Swede and Turnip.
Sweet corn, Tomato, Spinach, Pea, Onion, Marrow, Lettuce, Leek, Endive, Cucumber, Celery, Celeriac, Peppers, Beans and Aubergine.
Grow plants from the same groups together and change their position in the plot annually.
It is best to use at least a four-year rotation system because this is the number of years it takes for most soil-borne pests and diseases to decline to harmless levels. If your beds are divided into four groups, this means that members of each plant family won’t occupy the same spot more than once in a four-year period.
It is possible to create a more sophisticated crop rotation system by dividing your crops into more groups. You can then apply the same principals of planting the same plants together than not planting the same group in the same place until the third year. To help you do this we have colour coded the Veg Planner Wall Chart indicating which plants belong to the same more sophisticated groups.
