Orchard Tree Layout Calculator

A field can look large on paper, then lose several rows to turning space and a road. Enter the measured block and your chosen tree spacing to see how many whole places remain—and how many of those places are for pollinizers.

Measure one orchard block

Use a rectangular block. Rows run along its length. Enter spacing from a plan for your crop, variety, rootstock and equipment.

Changing units converts valid measurements.

m

Direction the tree rows will run.

m

Across the rows.

Choose your tree spacing

The page counts your layout; it does not recommend a spacing.

m

Center to center along each row.

m

Center to center across the block.

Headlands, borders, road and pollinizers

Leave these at zero if the field dimensions already describe the plantable block. A road here is centered and lies inside the headlands and borders.

m

Enter one end's depth. It is deducted twice.

m

Enter one side's width. It is deducted twice.

One centered, straight road.

%

Your chosen share, not a recommended rate. Zero is allowed.

Your orchard count

Whole positions for one uniform, straight-row block.

Trees that fit

Enter the block and spacing, then count tree places.

Check your spacing and turning clearances against the crop, mature canopy and equipment plan. A pollinizer percentage is only a count; variety compatibility and where the trees sit still need a planting plan.

Start with the block you can actually plant

Picture a field that is 100 metres long and 60 metres wide. It is tempting to divide its 6,000 square metres by the space for one tree. But a tractor needs room to turn at the ends, the outside rows need a border, and a road may run through the middle. Those spaces cannot hold orchard trees.

This calculator starts with the measured rectangle, takes out those working spaces, and counts the tree places that still fit. It is useful when you are sketching a block or checking a nursery order. It does not choose the right spacing or pollinizer variety for you.

How to use the calculator

Step 1

Measure in the direction the rows will run

Enter field length along the future rows and width across them. Pick metres or feet. If your field has a bend or a narrow corner, sketch it as separate rectangular blocks and calculate them one at a time.

Step 2

Use the spacing you plan to plant

Enter the distance between trees in a row and between rows. Open Headlands, borders, road and pollinizers if those spaces or trees belong in the plan. Headland and border entries are per side; the calculator deducts each twice.

Step 3

Count, then walk the sketch

Select Count tree places. The large number is all places, including pollinizers. Check the row count and places in each row against your sketch. The main-variety and pollinizer cards split that same total.

A block that loses space at both ends

Let's use that 100 by 60 metre field. Leave 5 metres for turning at each end and 3 metres along each side. The length for trees becomes 100 − 5 − 5 = 90 m. The width becomes 60 − 3 − 3 = 54 m.

Field100 × 60 mBefore access space
Keep clear5 m ends · 3 m sidesEach entry applies twice
For rows90 × 54 mBefore any inside road

At 5 metres between trees and 6 metres between rows, 18 whole places fit along each row and 9 whole rows fit across the width. That is 162 tree places. The plantable rectangle is 4,860 m², or 81% of the original field, but the count comes from 9 × 18—not from a rounded area percentage.

A road changes the count differently depending on its direction

Suppose this same cleared block needs a road. A road running along the rows takes width away. With a centered road 6 metres wide, the remaining 48 metres is split into two 24 metre sections. Each side fits four rows at 6 metre spacing. That makes eight rows, each still holding 18 trees: 144 tree places.

What if the road crosses the rows?

A 20 metre crossing road splits the 90 metre planting length into two 35 metre segments. Each segment fits seven trees at 5 metre spacing. Nine rows × (7 + 7) gives 126 tree places.

The calculator never carries leftover metres from one side of a road over to the other. You cannot plant half a tree in each section and call it one position. A road at an edge or several roads needs a separate-block sketch; this version models one centered road.

Why I would count rows before dividing area

Let's make that road narrower: 4 metres, still centered and running along the rows. It uses 360 m². Dividing the remaining 4,500 m² by 30 m² per tree might suggest 150 trees. Walk the rows instead: each side is 25 metres wide and fits only four complete rows. Eight rows × 18 trees is 144 places. The six-place difference is the space left at the edges of the two road sections.

That is the reason for counting whole positions. Area tells you how much ground remains; it does not tell you whether another full row fits where you need it.

Where pollinizers enter the count

Once you know the number of places, you can reserve some for pollinizer trees. They go inside the 162-place layout; they do not make the field hold more trees.

If your planting plan calls for 10% pollinizers, 162 × 10% is 16.2. Round up to 17 whole pollinizer trees, leaving 145 main-variety trees. With the 6 metre road along the rows, 10% of 144 is 14.4, so reserve 15 pollinizers and 129 main trees. The percent is a number you choose from a crop-specific plan, not a rate supplied by this page.

There is another step beyond arithmetic: put those pollinizers where their pollen can serve the main variety, and check bloom overlap and compatibility. A correct total with all pollinizers in the wrong corner is not a good pollination plan.

If your measurements are in feet

A 330 × 198 ft block with 15 ft headlands and 9 ft side borders has 300 ft of planting length and 180 ft of width. At 15 ft between trees and 18 ft between rows, that is 20 trees in each of 10 rows: 200 places. Reserve 12% for pollinizers and the order starts with 176 main trees and 24 pollinizers.

Write those two counts on the block sketch. If you plan extra trees for replacements, keep that as a separate line; replacement stock does not create more planting places.

The counting rule, if you want to check it by hand

Whole rows × whole tree places per row = total positions

Rows = floor(plantable width ÷ row spacing). Places in one uninterrupted row = floor(plantable length ÷ tree spacing). “Floor” means drop a remainder: 9.8 possible rows still means 9 complete rows.

For a centered road, first divide the remaining width or length into its two sections. Apply the whole-number rule to each section, then add the places. This is why a road can remove more positions than an area-only estimate suggests. Tree centers are treated as half a spacing from each planting-section edge. If your stakes require a different edge clearance, include that space in your entered headland or border.

Check the plan before you order trees

Tree spacing depends on more than this rectangle: crop, rootstock, canopy size, training system, sunlight and machinery all matter. The calculator accepts your chosen distances, but a high count does not prove they are suitable. The same goes for turning room; 5 metres in the example is an arithmetic input, not an equipment recommendation.

  • Measure the access space once. If the field dimensions already stop at a road or border, do not deduct it again.
  • Use one uniform block. Split irregular ground, sloping rows with different lengths, or multiple roads into smaller rectangles and add their counts.
  • Reserve pollinizer positions before ordering. Add a separate replacement allowance only if your establishment plan calls for one.
  • Mark the first and last trees in the field. A string line and stakes can reveal edges that a neat rectangle on paper misses.

Frequently asked questions

Are pollinizer trees added to the total?
No. They take some of the available tree positions. The total stays the same; the main-variety count falls by the number reserved for pollinizers.
What if my orchard does not need pollinizers?
Leave the pollinizer share at zero. The main-variety count will then equal all tree positions. Confirm pollination needs for your crop and varieties separately.
Does the calculator decide which pollinizer variety to plant?
No. It only reserves the percentage of positions you enter. Compatible bloom times and placement within the block need a crop-specific planting plan.
Why does a road remove more trees than its area suggests?
A centered road can split a row or a set of rows into two shorter planting sections. The calculator counts whole tree places in each section separately, so leftover space on one side cannot be moved to the other.
Does road width include the headlands and borders?
No. The road is measured inside the space left after the headland at each end and the side border on each side. Do not enter the same clearance twice.
Can I use a road along one edge?
This version models one centered road. For an edge road, subtract its width from the field width as part of your measured planting block, or calculate separate rectangular blocks.
Can I use triangular or contour planting?
The count assumes straight, equally spaced rows and one tree per position. A triangular or contour plan needs its own row stakes and edge treatment; do not treat this count as its exact population.
Why is the result zero?
A valid layout can still be too narrow for one full row or too short for one whole tree place after the clearances and road are applied. The result panel says which dimension prevented a fit.
How many extra trees should I order for replacements?
This result counts initial planting positions only. Decide a replacement reserve separately from nursery quality, establishment risk and your planting plan.
