Crop Rotation Checker
Compare the previous and proposed crop by plant family, flag same-family repeats and find different-family alternatives.
Make the next garden decision with less guesswork.
Rotation is most useful when it reduces repeated family-specific pest and disease pressure. Choose what grew in the bed before and what you plan to grow next to see whether the proposal repeats the same botanical family.
The checker maps common vegetables to botanical families and applies a conservative planning gap for an immediate same-family repeat. It does not claim that every garden needs a rigid rotation. Specific soil-borne diseases can require longer breaks, while small gardens may need more flexible management.
Put the result into a real garden situation.
Cabbage followed by broccoli looks like a crop change, but both are brassicas. The checker flags that as an immediate family repeat. Carrots, lettuce or beans would move the bed into a different family, although the final choice still needs to suit season, soil and the rest of the garden plan.
