There are several ways to rotate your annual veggie and fruit crops. The first one is by Plant Families.  I am not including flowers/blooms, herbs, perennial veggies and perennial fruits. Part of the reason is that I have a bed by the patio that I use for my herb garden, an area outside of my fenced in garden for my berry garden and a raised bed for other perennials like asparagus and strawberries.
Here is an option for crop rotation:
#1 Legume Plant Family – While this plant family builds soil health, most of the other annual veggies and fruits will deplete the soil.
â–²
#2 Brassica, Aster and Amaranth Plant Families
â–²
#3 Nightshade and Mallow Plant Families
â–²
#4 Grass and Cucurbit Plant Families
â–²
#5 Carrot, Onion and Morning Glory Families
You can put the Legume Family in Bed or Location #1, the Brassica and Aster Families in Bed or Location #2 and so on. Next year, you can put the Brassica and Aster Families in Bed or Location #1 and the Nightshade and Mallow Family in Bed or Location #2 and so on. If you don’t remember the veggie members of each plant family, then just click on the links.
While all of the families can be attacked by a pest or a bad bug, you might run into more pest issues with the Brassica, Cucurbit and Nightshade Plant families depending on your area. Some pests and diseases hang out in the soil. Overall, rotating your crops helps to trick the pests into moving elsewhere, minimize disease and improve soil health.
Since the Brassica and Aster Plant Families and the greens or leafy members (swiss chard and spinach) of the Amaranth Plant Family love to get a head start in the cooler weather and love nitrogen, I like to group them together in one raised bed. I use garden fabric and/or plastic on hoops to protect these plants from the fluctuating spring weather. In late spring and early summer, I use mosquito netting with the same hoops to protect the Brassica Family from pests like the cabbage moth. Also, once this bed is cleared, I can get ready for a fall harvest because these veggies grow well in the fall too!
I usually plant the veggies in the Onion Plant Family in one raised bed.  I plant garlic cloves and red shallot sets together in the fall. I use hoops with netting on top to keep the squirrels from digging up the garlic and shallots. Also, I try to save room to plant some onions and yellow shallots in the spring. Typically, my garlic, shallots and onions will be ready for harvesting around the same time in July. After I clear this bed, I can plant more goodies! It’s a way to practice some succession planting too!
