A Quick Guide to Crop Rotation & Vegetable Families
Want to be an advanced vegetable gardener? You will be when you know which vegetables are in which families. This is crucial info for healthy crop rotation in your garden (and you'll be able to astonish your friends with new vocabulary like cucurbits). You can memorize all the vegetable families -- or just bookmark this article and check on it before you plant each season. Crop rotation sounds like one of those headachey projects involving graph paper and Number 2 pencils. It's not so bad. You don't need graph paper, but you should make a map of your vegetable garden. Or pull out a piece of paper, sketch your plantings, and write the year on the map (because you'll need 4 to 5 years of records).
The basic rule: Wait 3 years until you replant families in the same place. Why? Soil borne diseases build up when similar plants grow in the same space for more than a year. You don't want to deal with club root, fusarium wilt, or vertciliium wilt, do you? If you keep moving the plants you'll help thwart the diseases. Just like any family, not all members of plant families look alike. See which relatives surprise you the most!
