Working

  1. 143560 / (20 x 20) = 109 per acre

Quick answer

Square layout: 43,560 divided by spacing squared. Triangular offset layout fits about 15% more trees in the same area.

The formula

trees per acre = 43560 / (row spacing x tree spacing)

How to use the Tree Spacing Calculator

  1. 1Enter the planting area in acres and the spacing between rows and trees.
  2. 2Use the mature canopy width as your minimum spacing for shade or fruit trees.
  3. 3Triangular offset rows fit more trees and shade the ground faster.

Frequently asked questions

How far apart should fruit trees be?

Dwarf 8 to 10 ft, semi-dwarf 12 to 15 ft, standard 20 to 25 ft. Closer than that and the canopies fight for light.

Why does triangular spacing fit more?

Offsetting each row by half a spacing packs circles more efficiently, adding roughly 15% more trees at the same distance apart.
