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.
What do I need to enter into the Tree Spacing Calculator?
Just 3 values: area, row spacing, spacing in row. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.
