Fruit Tree Orchard Spacing & Density Calculator

Calculate rows, trees per row, gross count, pollinizer allowance, replacement reserve, density, and optional yield from your own plot geometry.

Enter your details

Start with an example plot, then enter your own dimensions. Example distances are geometry demonstrations, not planting recommendations.

Advanced options: buffers, support-system examples & ordering

Hidden options still affect the result. Check the active allowances below before using the count.

How this tool works

Subtract end headlands and side allowances from the rectangular plot, then count positions at your entered spacing. Optional system presets are illustrations only; actual distances need local rootstock, cultivar, training and access guidance.

Assumptions & Physical Constraints:

Rows are treated as straight rectangular geometry. Irregular boundaries, slope, drainage, access roads, turning radius, utility setbacks, terrain, canopy management, and local regulation require a site plan.

Small-backyard geometry example: a 30 × 20 ft plot with 5 ft end and side allowances leaves 20 × 10 ft. At entered 10 × 10 ft spacing, that is 3 positions per row and 2 rows: 6 positions. This is not a recommended layout for a named rootstock.

Frequently Asked Questions

How much space do I need for a small backyard orchard?

Enter the usable plot and locally recommended spacing for the actual rootstock, cultivar and training system. Include paths, boundary clearance and support. A count of positions is not evidence that the trees will fit at maturity.

Can I turn this result into a printable tree register?

Yes. Use Create my orchard worksheet below the result. For larger plans, select a range of up to 30 positions before applying. Save a separate JSON project for each range. Tree IDs stay consistent for the same calculated layout; changing that layout can change their positions. Add verified identities before using the records.
