Question 1

How is plant count calculated for square spacing?

Accepted Answer

For square spacing, divide the bed length and width by the spacing to get the number of plants per row and per column, then multiply. A 10 ft × 4 ft bed with 1 ft spacing gives 10 × 4 = 40 plants.

Question 2

What is triangular (offset) spacing?

Accepted Answer

In triangular spacing, alternate rows are offset by half a space, and the vertical row distance shrinks to spacing × 0.866 (the height of an equilateral triangle). This packs about 15% more plants into the same area than square spacing.

Question 3

Does the unit matter?

Accepted Answer

No — as long as you use the same unit for the bed dimensions and the spacing, the plant count is identical. Use inches, feet, centimeters or meters consistently and the result is correct.
