Quality Assurance

Grading Protocol

Three tiers of quality. One standard of care. Every tree we source is graded before it ships.

The 10 Criteria

Selection Criteria for Estate & Legacy Grades
01

Visible Flare: Root collar must be at or above soil line. No buried flare, no girdling roots visible.

02

Trunk Taper: Consistent diameter reduction from base to crown. No reverse taper, no abrupt narrowing.

03

Central Leader: Single dominant leader (where species-appropriate). No co-dominant stems with included bark.

04

Branch Architecture: Well-spaced scaffold branches. No crossing, rubbing, or clustered attachment points.

05

Crown Symmetry: Balanced canopy from all viewing angles. No heavy lean, no one-sided growth from crowding.

06

Foliage Density: Full leaf coverage to branch tips. No interior die-back, no premature defoliation.

07

Bark Integrity: No mechanical damage, no sunscald, no canker. Bark texture consistent with species character.

08

Root Mass: Container-grown: no circling roots. B&B: solid, intact root ball at ANSI-specified minimum diameter.

09

Pest & Disease: No active infestation. No fungal fruiting bodies. No evidence of systemic decline.

10

Graft Union: (Where applicable) Clean, fully healed graft. No scion/rootstock incompatibility. No sucker growth below the union.
