Crop Rotation

When planting vegetables you must consider crop rotation even in the smallest veg patch. Growing the same type of vegetable in the same spot each season will encourage diseases to build up in the soil.

Vegetables fall into three main groups:-
1. 'Root crops' which include beetroot, carrots, parsnips and potatoes.
2. 'Brassicas' which include cabbage, cauliflower, broccoli, kale and sprouts.
3. 'Others' such as peas, beans, onions and leeks.

Divide your veg patch into three plots. Grow any group of veg in one plot only one year in three, rotating with the other two groups. In this way the disease is denied its host plant and is unlikely to build up in the soil.
