Discover How to Boost Your Vegetable Garden with Crop Rotation

Rotate Crops for a Healthy Garden

Vegetable gardening takes a lot of nutrients out of soil, and certain kinds of plants can bring diseases and attract pests. For this reason, you’ll want to rotate your crops to keep edibles at their best year after year. When you rotate crops, you interrupt the life cycle of certain pests and diseases and allow the soil to replenish. This organic technique will improve your gardening by keeping the soil fertile and discouraging plant disease and insect problems.


For example, tomatoes and corn are heavy feeders that will deplete the soil of nitrogen and phosphorus. Planting tomatoes in the same place each year will result in reduced crop yields and more susceptibility to disease and pests. By moving tomato plants to different parts of the garden each year, the soil will recover more quickly.

How to Make a Crop Rotation Plan

Crop rotation is a principle of large-scale farming and gardening, but the method can be incorporated in smaller home gardens by planning, either online or on paper in a garden journal. Group the vegetables in the garden according to their families — root vegetables, legumes and fruiting plants (see list below). Each year, move the different families throughout the garden.


Take the time to test the soil with a soil test kit and adjust the balance of nutrients with soil amendments like compost.


To make a crop rotation plan, draw out your garden into blocks, then label each block according to families. Next year, move the families clockwise in the plan. Aim for at least three years, or preferably four, before returning a plant family to its original plot.

Consider Cover Crops

Sometimes, you may have a need to leave a block of your garden fallow, that is, without a crop. In this case, use a cover crop or green manure to improve the soil. Fallow land can become weedy or erode, but when you use a green manure that is then turned under, you improve the soil structure and add nutrients back into the soil.


A cover crop is usually a legume because they take nitrogen from the air and fix it into the soil. When you use a mix of legumes and non-legumes like a grass or grain, the soil gets the benefit of the nitrogen and decaying plant matter. Warm-season cover crop options are soybeans, cow peas, buckwheat and sorghum. Crimson clover and rye are used in fall and winter.


As a sustained practice, cover crops will improve your garden year after year. Cover crops are turned into the soil in the next season, preferably just after they flower so that the seeds are not set. Down the road, those seeds could become weeds.
