Qualities of a SuperTree™                                  SuperTree Listings

 

1. Central Leader: Trees should have a single, relatively straight central leader and tapered trunk, free of codominant stems and vigorous, upright branches that compete with the central leader.

2. Main Branches (scaffolds): Branches should be distributed radially around and vertically along the trunk, forming a generally symmetrical crown typical for the species.  Branch diameter should be no greater than 2/3 (two thirds) the diameter of the trunk. The attachment of scaffold branches should be at wide angles and free of included bark.

3. Trunk diameter and taper shall be sufficient so that the tree will remain vertical without the support of a nursery stake.

4.  Roots:  The trunk, root collar (root crown) and large roots should be free of circling, girdling, and/or kinked (J-roots) roots. The root collar should be within 1" (one inch) above or below the soil surface.  The rootball periphery should be free of large circling and bottom–matted roots with roots radiating symmetrically from the center of the root ball.

Apricot – Planted 4 years ago in a 5 gallon pot.  Circling Root, J Root, and Girdling Roots are prevalent.  Cost $25 and 4 years waiting.  Tree weakened and died from sunscald.

Cedar Tree – Planted 3 years ago as a B&B tree.  Sisal twine did not deteriorate and girdled the trunk.  Tree blew over in a wind storm.
