The crop rotation planner generates a multi-year rotation schedule for your garden beds based on plant families. Rotating crops breaks pest and disease cycles and balances soil nutrients across seasons.

Rotation Tips
- • Keep the same family out of the same bed for at least 3 years
- • Follow heavy feeders (Solanaceae, Brassica) with legumes to restore nitrogen
- • Plant alliums (onions, garlic) after solanaceae to suppress soil pathogens
- • Roots and carrots benefit from beds that previously had legumes
- • Consider a fallow/cover crop year for highly infested beds
How to Plan Crop Rotation for Your Garden
Crop rotation is the practice of moving different plant families through your garden beds on a multi-year schedule. It's one of the most effective strategies for preventing soil-borne disease buildup and reducing pest pressure without chemicals.
Understanding Plant Families
Plants in the same botanical family share pest and disease vulnerabilities. The six key rotation families are: Solanaceae (tomatoes, peppers, eggplant, potatoes), Cucurbitaceae (cucumbers, zucchini, squash, melons), Brassicaceae (broccoli, cabbage, kale, radishes), Leguminosae (beans and peas), Alliaceae (onions, garlic, leeks), and Roots/Apiaceae (carrots, parsnips, beets, celery). Never follow one family with itself in the same bed the next year.
Building a 4-Bed Rotation
With four beds, you get a natural 4-year rotation. A classic sequence is: Bed 1 — Solanaceae (heavy feeder) → Bed 2 — Legumes (nitrogen fixer) → Bed 3 — Brassica (moderate feeder) → Bed 4 — Roots (light feeder). Each year, every crop moves one bed forward. After four years, the cycle repeats with refreshed soil biology.
Keeping Records
The most common crop rotation failure is simply forgetting which family was in which bed. Use a simple garden journal, a spreadsheet, or a photo taken each spring. Label beds with a permanent marker on a stake. Many gardeners use colored flags — one color per plant family — to quickly see the rotation at a glance without consulting notes.

Why is crop rotation important?
Rotating crops breaks pest and disease cycles specific to plant families. For example, tomato hornworms, clubroot, and onion white rot all overwinter in soil. Moving host plants to a different bed each year starves these pests. Rotation also balances soil nutrients — legumes fix nitrogen while brassicas and corn are heavy feeders.
What are the main plant families for rotation?
The six key rotation families are: Solanaceae (tomatoes, peppers, eggplant, potatoes), Cucurbitaceae (cucumbers, squash, melons), Brassicaceae (cabbage, broccoli, kale, radishes), Leguminosae (beans, peas), Alliaceae (onions, garlic, leeks), and Apiaceae/Roots (carrots, parsnips, beets). Keep the same family out of the same bed for at least 3 years.
How many beds do I need for a proper rotation?
Four beds is the ideal minimum — one for each of the four main plant families (Solanaceae, Brassica, Legume, and Cucurbit/Root). With fewer beds you can still rotate, but the gap between same-family plantings will be shorter. Six or eight beds allow even better disease breaks and more flexibility in scheduling.
Can I rotate in a raised bed garden?
Yes, and raised beds make rotation easier because each bed is clearly defined. The key is keeping records — note which plant family was in each bed each year. Many gardeners label their beds with a color code or number system to track the rotation visually over time.
