You may have heard about crop rotation for farmers, where they let a field rest every few years for the soil to replenish or change the types of crops in one place year after year. Although our backyards are much smaller than a farm, the same logic applies to healthy vegetable gardening! Keep reading to discover why this practice can save you a ton of hassle by preventing pests and diseases and promoting super healthy crops.
What Is Crop Rotation?
Crop rotation involves changing the crops you grow in one specific garden plot so that you’re not planting the same veggies in the same location for more than a year or two in a row. Farmers and gardeners have been practicing crop rotation for millennia; we have evidence that it was commonplace in ancient societies in Greece, Rome, China, and the Middle East at least as early as 6000 BC. Thanks to crop rotation, agriculture in these cultures was successful before the invention of chemical fungicides, herbicides, and pesticides!
Why Is Crop Rotation So Important?
You’ve likely heard of the Irish potato famine—a tragedy that led to the mass emigration of Irish immigrants. The famine occurred from a plant pathogen known as Phytophthora infestans, which attacked the potato crops the Irish depended on for survival. Pathogens like this take hold when the same crops are grown in the same area every year.
On a home garden scale, an example of not rotating your crops would mean planting your tomato plants in the same sunny spot in your garden year after year. While you may think this spot is the perfect place for your tomatoes to bask in the sun, it also means that the garden pests and diseases that feed on tomato plants will start to make this spot their favorite hangout. Worse still, as old tomato plants die, the pathogens that attacked them will continue to live on the decaying plant matter in the soil while planning a stronger attack on next year’s plants!
By contrast, you can practice crop rotation by planting your tomatoes in that spot in year one of a four-year rotation, then planting beans there in year two, followed by carrots in year three, and salad greens in year four. Since you’re planting a totally different plant family each year, you’re keeping those pesky pathogens guessing and improving the biodiversity in the soil ecosystem; this leads to a more balanced garden environment and, in turn, healthier plants with better yields.
Crop Rotation Basics
There is a lot of science around crop rotation in a commercial context, but simple solutions are the best option for your home garden. It’s important to understand that successful crop rotation calls for the rotation of plant families, not just specific plant species. For example, rotating tomatoes with peppers will not be particularly successful because the plants are closely related and vulnerable to many of the same pathogens and pests.
Instead, the most basic approach to crop rotation is to remember this rotation: fruit, root, leaf, legume. While there are definitely more details if you want to elevate your crop rotation practice in the future, this is a simple way to ensure that each crop you plant is different enough from the last.
Fruit Crops Include:
- Summer squash
- Winter squash
Root Crops Include:
- Sweet potatoes
Leaf Crops Include:
- Swiss chard
Legume crops include:
