You should usually plant apple trees between about 8 and 25 feet apart, depending mainly on whether they’re dwarf, semi-dwarf, or standard trees.

Quick Scoop

  • Dwarf apple trees:
    • 8–10 feet (2.5–3 m) between trees in the row.
* 12–15 feet (3.5–4.5 m) between rows if you’re doing an orchard-style layout.
* Good for small yards, easy pruning and picking.
  • Semi-dwarf apple trees:
    • 12–15 feet (3.5–4.5 m) between trees.
* 15–20 feet (4.5–6 m) between rows.
* Popular “backyard orchard” choice because they balance size and yield.
  • Standard (full-size) apple trees:
    • 18–25 feet (5.5–7.5 m) between trees.
* 20–30 feet (6–9 m) between rows for big, traditional orchards.
* Best if you’ve got lots of space and want big, long-lived trees.

Rootstock cheat sheet (orchard-style spacing)

Many modern apples are sold on named rootstocks that control how big they get. Typical minimum spacings between trunks include:

[3] [3] [3] [3] [2] [5][2]
Rootstock / Size Typical spacing between trees Notes
M27 (very dwarf) ≈ 10 feet (3 m) Very small, needs support, good for tight spaces.
M9 (dwarf) ≈ 12 feet (3.6 m) High-yield, compact, often grown in rows with posts/wires.
M26 (dwarf–semi-dwarf) ≈ 15 feet (4.5 m) Still manageable height, more root spread.
MM106 (semi-dwarf) ≈ 20 feet (6 m) Good all-round garden tree, needs more room.
Semi-dwarf (general) 12–15 feet 15–20 feet between rows.
Standard (full- size) 18–25 feet 20–30 feet between rows.

Why spacing matters (in plain language)

  • Apple roots can spread 1.5–2 times beyond the canopy, so crowding makes them compete hard for water and nutrients.
  • The canopy of standard trees can reach 20–30 feet across; dwarf trees 10–13 feet, so they need enough room for light and air.
  • Too-close trees = shade, poor air flow, more disease risk, smaller crops over time.

Pollination and layout

Most apple varieties need a different variety nearby for cross‑pollination.

  • Try to keep compatible pollinator trees within about 50 feet of each other so bees can easily move pollen between them.
  • In a small yard, planting two different varieties 10–20 feet apart usually works well for pollination.

Simple rule-of-thumb for your yard

  1. Find out the tree size or rootstock (dwarf, semi-dwarf, or standard).
  2. Use this quick spacing guide:
    • Dwarf: 8–10 ft
    • Semi-dwarf: 12–15 ft
    • Standard: 18–25 ft
  1. If you’re unsure what you bought, assume semi-dwarf and give at least 12–15 ft between trees.

If you tell me your tree type (or what the nursery label says), I can help you pick an exact spacing and layout for your specific spot.

TL;DR: Most home growers plant apple trees about 12–15 feet apart; go closer (8–10 ft) for dwarfs and wider (18–25 ft) for big, standard trees.
