Rotating Vegetables by Family
Rotating vegetables is always recommended, but to do it properly, one needs to know which vegetables are in the same family. Related vegetables share disease problems, so a true rotation needs to be between vegetable families. Usually a 3-year rotation is advised, meaning that there will be 2 years of unrelated vegetables in the middle, between related vegetables.
