Crop Rotation Made Simple for Home Gardens
Year one goes great. By year two or three, the tomatoes wilt and the cabbage struggles in the same bed that used to thrive. The cause is soil-borne pests and disease building up under the same crop family. Crop rotation breaks that cycle, and for a home garden it is simpler than it sounds.

Why rotation works
Pests and diseases that target a crop family survive in the soil and multiply when you plant that family in the same spot year after year. Move the family somewhere else and the leftover pests starve. Extension services recommend waiting 3 to 4 years before a family returns to the same bed.
Rotation also balances the soil, since different families feed differently. Legumes even add nitrogen for the next crop.
Group your crops by family
You rotate families, not single crops, because relatives share the same pests:
- Nightshades: tomatoes, peppers, eggplant, potatoes.
- Brassicas: cabbage, broccoli, kale, collards, radish, turnip.
- Legumes: beans and peas, which add nitrogen to the soil.
- Alliums: onions, garlic, leeks.
- Cucurbits: squash, cucumbers, melons.
A simple 4-bed rotation
With four beds, give each family its own bed and shift everything one bed over each year. A handy order: legumes, then leafy brassicas, then heavy fruiting nightshades and cucurbits, then roots and alliums. The legumes leave behind nitrogen the hungry crops use next.
Keep a quick note of what grew where. The planting log does this so next year's plan can warn you if a family is about to repeat.
If you only have one bed
You can still rotate within a single bed. Split it into sections and swap families from one end to the other each year, and lean harder on compost to keep the soil healthy. It is not a full reset, but it still slows pest buildup compared with planting the same thing in the same spot.

Questions, answered straight
Aim for 3 to 4 years before a crop family returns to the same bed. That is long enough for most soil-borne pests and diseases to die back.
By family. Tomatoes, peppers, and potatoes share pests, so moving a tomato to where the peppers were does not help. Move the whole family together.
Yes. Even in one bed, split it into sections and swap families end to end each year. Add compost to keep the soil balanced.
Heavy feeders like tomatoes, squash, and corn. Beans and peas leave nitrogen in the soil that those hungry crops use the next season.
