About This Tool

### Fit More Plants in Your Garden When buying seeds or starter plugs, the label always says "Space 12 inches apart." But how do you arrange them efficiently? **Plant Spacing Calculator** compares strict **Row** spacing vs **Triangular** spacing to maximize your yield. ### Square Foot Gardening? This tool is perfect for raised beds. By using "Triangular" (or Hexagonal) spacing, you offset each row so plants sit in the gaps of the previous row. This mimics nature and often lets you fit **15% more plants** in the same space without overcrowding roots.

Key Features

  • **Dual Calculation**: See 'Grid' and 'Triangular' counts side-by-side.
  • **Yield Maximizer**: Prove to yourself that staggering rows works better.
  • **Any Area**: Works for huge fields or tiny balcony planters.
  • **Instant Math**: No more guessing if you need 6 or 8 tomato plants.

Frequently Asked Questions

What is Triangular Spacing?

Triangular (or Hexagonal) spacing offsets rows so plants fit into the gaps of the previous row. The distance between EVERY plant is equal, creating a honeycomb pattern that optimizes space.

Does this apply to all plants?

Yes, but be careful with plants that need machine harvesting (tractors need straight rows). For hand-picked home gardens, triangular is almost always superior.
