Do you have to rotate crops?
Most gardeners would agree that crops should be rotated, but the reality is that this is not always necessary. If you have a small garden, it may even prove impossible. If you are growing any perennial fruit, vegetables or herbs, you already have crops that aren’t getting rotated.
How do you rotate crops?

Ideally, rotate a vegetable (or vegetable family) so that it grows in a particular place once out of every 3 to 4 years. For example, if you planted tomatoes in the same garden bed year after year, they’re more likely to be hit by the same pests or diseases that affected your tomato crop last year.
How does crop rotation help the environment?
Crop rotation practices can result in increased soil carbon content through high crop cover periods, reduced frequency and tillage intensity. Increase in the use of forages in crop rotations can result in better crop residue management while higher soil-carbon content helps combat climate change.
What is crop rotation in agriculture?
Crop rotation is defined as a “system of growing different kinds of crops in recurrent succession on the same land” (Martin et al., 1976). Rotating different crops year after year adds various economic and environmental benefits. In addition, crop rotation is helpful in long-term soil and farm management.
How important is crop rotation in the home garden?
