How to use
Enter the bed length and width and the spacing between plants (in inches). The calculator divides the area by the spacing square to give the plant count for a grid layout.
FAQ
Does this use a grid or triangle spacing?
It assumes a square grid. Triangle (offset) spacing fits about 15% more — add that mentally for dense beds.
What if my spacing is in centimetres?
Convert to inches (1 in ≈ 2.54 cm); the input is in inches for standard gardening guides.
Should I buy spares?
Yes — a few spares cover losses from transplant shock or pests.
