Square Foot Gardening: High-Yield Method for Small Spaces

Square Foot Gardening (SFG)—popularized by Mel Bartholomew in 1981—revolutionizes home food production through intensive, organized planting in small, raised beds. It's biointensive, organic, beginner-friendly, and remarkably productive.

Core Principles

• Small space: 4×4 foot beds standard
• Grid system: 1-foot squares (16 per bed) marked with twine, lath, or string
• Perfect soil: "Mel's Mix" = ⅓ peat moss/coir, ⅓ vermiculite, ⅓ compost. Fills 6-inch deep boxes.
• Weed barrier: Landscape fabric under boxes with Mel's Mix
• No walking on soil: Work from paths only

Plant Spacing Per Square Foot

• 1 per square: Tomato, pepper, broccoli, cabbage, basil, oregano
• 4 per square: Lettuce, chard, marigold, strawberry
• 9 per square: Bush beans, spinach, beets, garlic
• 16 per square: Radish, carrot, onion, scallion
• Vertical squares: Trellis for peas, cucumbers, pole beans, tomatoes
• Deep squares: 12-inch sides for potatoes, sweet potatoes

Maintenance

• Add compost annually to maintain fertility
• Hand-water (soil holds moisture exceptionally well)
• Dense planting = minimal weeding
• Companion planting = natural pest management

Benefits Over Traditional Gardening

• 80% less space, 50% less water, 90% less work (per Bartholomew)
• No chemical fertilizers—soil health self-sustaining
• Adaptable: urban patios, rooftops, deserts, disability-accessible
• Continuous harvest through succession planting

Getting Started

1. Build/buy 4×4 box (6+ inches deep)
2. Lay weed barrier
3. Fill with Mel's Mix
4. Install grid
5. Plant per spacing guide

Square Foot Gardening distills vegetable growing to its efficient essence—maximum nutrition from minimum space, time, and effort.
