Why You Shouldn’t Combine Individual Beds and Enter into Calculator as One
At 12” spacing, each 100 square foot square has 36 square feet of “edge”, or unplantable space. Four individual beds with 36 square feet unplantable space each, equals a total of 144 square feet that is unplantable.
At 12” spacing, a 400 square foot square has 76 square feet of “edge”, or unplantable space.
If beds are not entered individually, the proper area of unplantable space is underestimated, therefore; the plant quantity is overestimated. In the above example, combining beds results in only 76 square feet of unplantable space, instead of the actual unplantable space of 144 square feet.
