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.
