The Fat-C Method

his planting method involves tilling a 3×3 square of soil and leaving one square on the edge untilled, planting just 8 crops instead of 9. This is the most efficient method of planting crops during the early stages of the game since the center crop is inaccessible without an upgraded watering can.
