Row: Plants = (Length/Spacing + 1) × (Width/RowSpacing + 1) | Triangular Row Spacing = PlantSpacing × √3/2
Frequently Asked Questions
What spacing should I use for common vegetables?
Common spacing: Tomatoes 24-36", Peppers 18-24", Lettuce 6-12", Beans 4-6", Corn 12", Squash 36-48", Carrots 2-3", Onions 4-6", Cucumbers 12-18" (with trellis). Always check seed packet recommendations.
What is square foot gardening?
Square foot gardening divides beds into 1-foot squares, each planted with a specific number of plants based on spacing: 1 plant per square (12" spacing), 4 per square (6"), 9 per square (4"), or 16 per square (3").
Does triangular spacing really help?
Yes, triangular (offset/staggered) spacing fits about 15% more plants than a square grid while maintaining the same minimum distance between plants. It is especially useful for ground covers, flowers, and dense plantings.
