Watering identity & plant spacing
Two handy conventions: an inch of water over a square foot is 0.623 gallons, so a week's watering is area × inches × 0.623; and a bed needs about area ÷ spacing² plants on a square grid (about 15% more on a triangular grid). These are labeled planning conventions. Use them in the watering-needs and plant-spacing tools.
| Spacing (on center) | Plants per 100 sq ft (square) | Plants per 100 sq ft (triangular) |
|---|---|---|
| 0.50 ft | 400 | 461 |
| 1.00 ft | 100 | 115 |
| 1.50 ft | 44 | 51 |
| 2.00 ft | 25 | 28 |
| 3.00 ft | 11 | 12 |
Watering: an inch of water over a square foot is 0.623 gallons, so a week is area × inches × 0.623. Plant count = area ÷ spacing² (square); triangular packs ~15% more. Labeled planning conventions.
