ABSTRACT:
An Expandable Tree Support Collar to aid young transplanted tress or other unstable plantings to remain upright until a sufficient root structure develops. Assembled unit consists of an expandable one and one quarter turn coil to which supporting wires are attached. The device is slipped over the trunk of a tree and the supporting wires affixed to ground attachment points. The design simplifies and speeds tree supporting and eliminates the possibility of trunk constriction possible with other tree support methods.
