The most basic form of crop rotation is also the simplest: never plant the same thing in the same place twice. A good crop rotation plan is a sort of seasonal dance in which the crops move from spot to spot, and it helps create a garden that is constantly new and intriguing.
The aim of rotation is threefold: to balance nutrient demands, foil insect and disease attacks, and deter weeds. Figuring out rotations, and finding an elegant solution to the puzzles of planning, can be fascinating work.
