Quick Summary & Key Answer

To calculate trees per acre, divide 43,560 (the square feet in one acre) by the product of your in-row spacing and between-row spacing. For example, a 10' × 10' spacing provides 100 sq ft per tree, yielding 435 trees per acre.

1 Acre = 43,560 square feet.
Standard timber pine reforestation spacing is 8' x 8' (680 trees/acre).
Standard semi-dwarf apple orchard spacing is 12' x 18' (201 trees/acre).

Note: Formula: 43,560 sq ft / (In-Row Spacing × Between-Row Spacing). Order 5-10% extra seedlings to account for mortality.

Common Tree Spacing Densities

Choosing proper tree spacing balances root competition for moisture and sunlight against desired canopy closure.
