  1. 1.The 4-Foot Width Rule

Raised beds are the ultimate game-changer for gardeners dealing with stubborn clay, rocky limestone, or contaminated urban plots. By elevating your growing zone, the soil warms up up to three weeks earlier in spring and never gets compacted by heavy footsteps.

Never build a raised bed wider than 4 feet (1.2 meters) if you can access both sides, or 3 feet if it backs up against a fence or wall. The human arm reaches comfortably about 2 feet; any wider, and you will be forced to step onto the bed, crushing the delicate air channels your roots depend on.
