Plant Spacing & Layout

Tree Planting Spacing Calculator

Pick a tree type and enter your available space to see how many trees fit, how far apart to plant them, and how big they get at maturity.

How to use the tree spacing calculator

Choose your tree type, enter the length and width of the space you have in feet, and pick a planting pattern. Press Calculate Tree Spacing and you will see how many trees fit, the recommended distance between trunks, how wide and tall each tree gets at maturity, whether the canopies will touch or leave gaps, and how far to keep the trees from buildings and fences. Change any input and the result updates instantly.

Why correct tree spacing matters

Spacing is the decision new growers most often get wrong, and it is hard to fix once trees are in the ground. Plant too close and the trees compete for light, water, and nutrients; airflow drops, which encourages fungal disease; and the canopies crowd into a tangled mass that is difficult to prune, spray, and harvest. Plant too far apart and you waste space and lose yield. Good spacing gives each tree room for its full canopy, keeps air moving, and makes every other task easier for the life of the tree.

Spacing is driven by mature spread

The right distance depends on how wide a tree grows, not how tall. That is why rootstock matters so much for fruit trees: a dwarf apple may only spread 8 feet and can be planted close, while a standard apple spreads around 20 feet and needs far more room. As a starting point, set trees at least as far apart as their mature spread, and a little more if you want clear space to walk and work between them. Measure spacing from trunk to trunk, often called "on center".

Typical spacing by tree type

  • Dwarf apple, sour cherry: about 8 to 10 feet.
  • Semi-dwarf apple, peach, apricot, fig, ornamental: about 15 feet.
  • Pear, plum: about 20 feet.
  • Standard apple, sweet cherry: about 25 feet.
  • Large shade tree: about 30 feet.
  • Blueberry bushes: about 4 feet; evergreen privacy screens about 5 feet.

Keep trees clear of structures

Roots and branches both need room, so keep trees away from houses, driveways, septic lines, and fences. A practical guide is to plant at least half the mature spread plus a few feet from any structure; this tool adds a 5-foot buffer to half the spread. Large trees and those with aggressive roots deserve extra distance, and many municipalities set legal minimums from property lines and sidewalks. When in doubt, give a tree more space than you think it needs — it will grow into it.

Frequently Asked Questions

How far apart should I plant fruit trees?

It depends on the rootstock and type. Dwarf apples need about 8 feet between trunks, semi-dwarf about 15 feet, and standard apples or sweet cherries up to 25 feet. Peaches, plums, apricots, and figs usually want 15 to 20 feet. The spacing is measured trunk to trunk, and it is set by the tree’s mature spread so the canopies have room without crowding.

How do I know how many trees will fit?

Divide your available length by the recommended spacing to get the number of trees per row, then divide your width by the spacing to get the number of rows, and multiply the two. This calculator does that automatically for single-row, double-row, and full-grid layouts, and rounds down so every tree has its full spacing.

How far should trees be from a house, fence, or property line?

A good rule of thumb is at least half the mature spread plus a few feet of buffer. This calculator suggests planting at least half the spread plus 5 feet from buildings and fences. Large shade trees may need much more room, and many areas have legal setbacks from property lines, so check local rules before planting big trees.

What is the difference between mature height and spread?

Height is how tall the tree gets; spread is how wide the canopy grows. Spread is the number that drives spacing, because two trees crowd each other when their canopies overlap. A tree with a 20-foot spread planted on 25-foot centers will have open space between canopies, while one planted on 15-foot centers will have branches that touch or overlap.

Can I plant trees closer for a privacy screen or hedge?

Yes. For screens and hedges you deliberately plant closer than orchard spacing so the canopies knit together into a solid wall. Evergreen privacy plants are often set around 5 feet apart for that reason. The trade-off is more competition for light, water, and nutrients, so the trees may stay a little smaller and need more attentive care.

Does planting pattern change how many trees I can grow?

It does. A single row uses only the length of your space, a double row adds a second parallel line, and a grid fills the whole area with evenly spaced rows. A grid fits the most trees but needs the most width, while a single or double row is ideal along a driveway, path, or boundary. Pick the pattern that matches the shape of your space.
