French-Intensive Vegetable Garden: Double-Dug Beds for Maximum Yield in Minimal Space

Size: 4 × 12 ft | Time: 2 days planting + prep | Cost: $175

Shoulder-to-shoulder planting in double-dug soil yields more food per sq ft than any system. Roots grow down, not out, allowing tight spacing and high production. Close spacing shades out weeds.

Soil Preparation: Double-Digging

Dig out top 10–11″; pile aside. Loosen bottom layer another spade-depth (dig and turn in place, or use spading fork). Return topsoil, mixing ⅓–½ cu yd compost into entire bed. Hard work, extremely rewarding.

Plant List (spacing in inches)

• A. Pole beans, 24 seeds (2 tepees); 4″
• B. Sunflowers, 6 (grouped); 18″
• C. White cosmos, 12 (grouped); 6″
• D. Tomatoes, 4; 21″
• E. Parsley, 10; 6″
• F. 'Tricolor' sage, 1; 15″
• G. 'Golden' sage, 1; 15″
• H. Chives, 2; 6″
• I. Zucchini, 2; 15″
• J. Sweet basil, 2; 6″

Schedule

A Few Days Ahead

1. Choose sunny, all-access spot.
2. Order amendments; rent tiller if not hand-digging.
3. Order region-suited seedlings; buy bamboo poles, tomato cages.
4. Remove weeds.

Weekend Day 1

1. Double-dig bed (per above).
2. Erect bean tepees: tie four 8-ft bamboo poles 6″ from end; stand upright.
3. Water thoroughly; let settle overnight.

Weekend Day 2

1. Set most plants in diamond pattern per spacing.
2. Plant pole beans on tepees (3 seeds per pole).
3. Cage tomatoes (1 plant per cage center).
4. Snake soaker hoses through beds.
5. Mulch: Coco Grow (or black plastic in mountains/cool summers for warmth).
6. Fertilize at planting with fish emulsion spray; repeat every 2 weeks. Stop feeding fruiting plants (tomatoes, beans, peppers) at flowering; continue feeding leaf crops. Boost all with 5-5-5 organic fertilizer twice per season.
