Depending on your garden you sort of do crop rotation anyways in many setups.
Like if you have four quarter plots of a 48ft2 piece of lawn and do a different crop in each quarter, then rotate the next year. Makes it easy for even yourself to harvest. Easier to notice where your ripe beans to harvest are when they aren’t mixed in with your corn plants.
