Crop rotation has traditionally been used for hundreds of years to get the most of the soil’s nutrients and reduce the risk of microbial diseases and insect infestation, by moving your crops each year to a different area of soil. Crop rotation can help to improve the health of your garden, allotment or smallholding by replenishing nitrogen levels, and limits the need for pesticides and fertilizers, making it a highly effective way of gardening organically.
Know your crops
Begin planning your crop rotation by knowing your crops and their properties. Divide them into families:
Alliums (onion): onions, leeks, shallot, chive and garlic
Umbeliferae (carrot and root): carrot, parsnip, celeriac
Asteraceae (sunflower): sunflower, lettuce, leafy greens
Brassicas (cabbage): cabbage, Brussels sprout, broccoli, kale, leafy greens
Chenopodiaceae (beetroot): spinach, beetroot, chard
Cucurbits (squash and marrow): cucumber, melon, squash, gourd, pumpkin, courgette
Solanaceae (potato and tomato): tomato, pepper, aubergine, potato
Legumes: pea and bean
Grass: wheat, corn, rye, oats
Once you’ve sorted your crops into their key families, you can plan where each will be planted in order to make the most of the benefits of crop rotation.
To make the most of using crop rotation in your garden, allotment or smallholding, it is wise to spend some time planning, with a pencil and paper, where each group of plants will grow in their first year, and where and when moving will take place in subsequent years.
Draw out a rough layout of your garden, with each bed plotted out and marked with its dimensions. Cut another piece of paper into smaller labels, each representing a different crop family. It can help to label each using a different colour to make it easier to visualise the different plant types in your garden. Once each plant type is established, spend some time working out a system in which they can be moved each season in a logical manner- often left to right, right to left, clockwise or anti-clockwise works best. Take photos of your finished plans so you remember them when it comes to putting them into action.
Don’t expect immediate results- there is only so much you can work out from planning on paper alone. A great deal of learning about which combinations will come from putting your plans into action, and improvising as you go along.
