Master high-density intensive gardening principles. Populate your 4x4 raised bed grid using companion planting rules, master soil science tips, and complete the final certification quiz.
Developed by Mel Bartholomew, the Square Foot Gardening system organizes raised beds into 1x1 foot grids, eliminating single-row spacing waste. By utilizing a "Mel's Mix" soil substrate (1/3 vermiculite, 1/3 peat moss, 1/3 blended compost), roots experience loose aeration, optimal water retention, and high nutrient availability without compacted walking paths.
Companion Planting Synergy: Grouping mutually beneficial species enhances pest deterrence (e.g., marigolds releasing root exudates discouraging nematodes), optimizes vertical space (vining legumes fixing atmospheric nitrogen for heavy-feeding brassicas or solanaceae), and attracts beneficial pollinators.
