The recommended spacing for planting apple trees depends largely on the rootstock type and the mature size of the tree:
- Dwarf apple trees should be planted about 8 to 10 feet apart.
- Semi-dwarf apple trees require spacing of about 12 to 15 feet.
- Standard apple trees need more space, typically 18 to 25 feet apart.
- Columnar apple trees can be planted very close, about 2 to 3 feet apart.
These distances are measured between the trunks at planting time, not the eventual canopy spread
. More specifically, spacing recommendations by rootstock include:
- M27 rootstock: about 3 meters (10 feet) apart
- M9 rootstock: about 3.6 meters (12 feet) apart
- M26 rootstock: about 4.5 meters (15 feet) apart
- MM106 rootstock: about 6 meters (20 feet) apart
In orchard settings, spacing can be wider to accommodate tree growth and machinery, with standard trees spaced up to 25 feet apart, while backyard growers aiming for high density can plant trees closer but must manage with regular pruning
. In summary, for home planting:
- Plant dwarf trees 8-10 feet apart
- Semi-dwarf trees 12-15 feet apart
- Standard trees 18-25 feet apart
Adjust spacing based on your rootstock and how much pruning and maintenance you are willing to do
