Orchard Planting Layout Calculator

Calculate required seedlings and estimated row count from area, row spacing, tree spacing, aisle width, and pollinizer ratio.

Works for apples, citrus, mangoes, olives, and other orchard crops with very different tree spacing.

Works for apples, citrus, mangoes, and olives Estimates rows and tree count from area Calculates pollinizer ratio and spare seedlings together Supports m² / ha / acre and m / cm / ft / in

How to use

  1. Choose the area and its unit.
  2. Enter row spacing, tree spacing, aisle width, and the pollinizer ratio.
  3. If needed, refine the field aspect ratio and spare rate in Settings.
  4. Check the result, then copy the report or share URL for nursery orders and field planning.

Sample cases

Estimate a 1 ha apple orchard

Input

Area 1 ha, row spacing 4 m, tree spacing 2 m, aisle width 3 m, pollinizer ratio 10%, field aspect ratio 1.0, spare rate 5%

Output

Estimated rows 24, trees per row 50, planting positions 1,200, pollinizer trees 120, spare seedlings 60, required seedlings 1,260

Estimate a 4 acre olive orchard

Input

Area 4 acre, row spacing 20 ft, tree spacing 12 ft, aisle width 10 ft, pollinizer ratio 5%, field aspect ratio 1.0, spare rate 5%

Output

Estimated rows 20, trees per row 34, planting positions 680, pollinizer trees 34, spare seedlings 34, required seedlings 714

See pollinizer rounding in a 9 m² block

Input

Area 9 m², row spacing 1 m, tree spacing 1 m, aisle width 0, pollinizer ratio 10%, field aspect ratio 1.0, spare rate 0%

Output

Planting positions 9, pollinizer trees 1, main cultivar trees 8

Glossary

Row spacing

The distance between the centers of neighboring rows.

Tree spacing

The distance between the centers of neighboring trees in the same row.

Aisle width

The width reserved for access by people or machinery.

Pollinizer tree

A tree variety that helps with pollination and is counted separately.

Spare seedlings

Extra seedlings ordered to cover replacements and losses.

Field aspect ratio

Long side ÷ short side. A value of 1.0 assumes a square block.

Formulas

The calculator normalizes to m² and m internally.

  • Short side = √(area ÷ field aspect ratio)
  • Long side = short side × field aspect ratio
  • Usable short side = max(short side - aisle width, 0)
  • Estimated rows = floor(usable short side ÷ row spacing)
  • Trees per row = floor(long side ÷ tree spacing)
  • Planting positions = estimated rows × trees per row
  • Pollinizer trees = ceil(planting positions × pollinizer ratio ÷ 100)
  • Spare seedlings = ceil(planting positions × spare rate ÷ 100)
  • Required seedlings = planting positions + spare seedlings

Notes

  • This tool gives an estimate only. Real layouts change with field shape, slope, borders, drainage strips, and road access.
  • The pollinizer ratio is only a count split. Adjust the actual placement for the crop and pollination requirements.
  • When you use imported seedlings or overseas cultivars, follow local production standards and nursery grades first.

Frequently asked questions

Is the row count exact?

No. It is an estimate from the area and field aspect ratio, not a CAD-accurate layout. If you know the block shape, set the aspect ratio to get closer to the real row count.

How is aisle width used?

It is treated as the main aisle deducted from the short side of the block. If you have several aisles, enter the total width.

Does the pollinizer ratio decide the row pattern?

No. It only splits the total trees into main cultivar and pollinizer counts. The actual row pattern depends on the crop and orchard design.

Can I use it for crops other than apples?

Yes. It works for citrus, mangoes, olives, and other orchard crops with known tree and row spacing.

Can I switch units?

Yes. Area supports m² / ha / acre / ft², and length supports m / cm / ft / in.
