Plant Spacing Calculator

2021-6-18  The formula to find plant spacing from plant density is different depending on the type of grid. For a square grid, the formula is: plant spacing = √(1 / density) and for a triangular grid, the formula is: plant spacing = √(2 / (√3 * density)) where density could be plants/m 2 or plants/ft 2 and plant spacing could be m or ft, accordingly.
