How this tool works

Modern high-density orchards utilize dwarfing rootstocks on wire trellises spaced 4–6 feet apart in rows with 10–14 foot alleys for equipment. Freestanding semi-standards (MM.111) require 14–18 feet in-row spacing to prevent light interception shadowing.

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.

Dwarf Tall Spindle: 4–6 ft in-row x 10–14 ft between rows = 500 to 1,000 trees per acre.

Frequently Asked Questions

How much space do I need for 2 backyard dwarf apple trees?

Two dwarf trees (M.9 or G.41) require a trellis strip 10–12 feet long by 4–6 feet wide in full sun.
