Plant Spacing Calculator

Proper spacing prevents disease, reduces competition for nutrients, and maximizes yield. Triangular (offset) layout fits about 15% more plants than a square grid in the same area.

Spacing requirements are usually listed on seed packets or plant labels
Dense planting suppresses weeds but increases humidity — good for some plants, bad for others
Tall plants should be placed at the north end of the bed to avoid shading shorter plants
Add 15–20 cm border around the bed edge for the outer plants
