A tree anchoring apparatus, a tree anchoring kit and a method of anchoring of a tree on a roof deck is provided consisting of three tree cabling systems attached to a tree. Each tree cabling system can exist in one of two states, depending on whether there is slack in the system or whether there is resistance due to movement of the tree from a vertical position to a horizontal position. In a wind event that causes the tree to move from a vertical position to a horizontal position, one or more of the tree cabling systems will experience resistance that keeps the tree in a horizontal position. When the wind event is over, the tree can be returned to a vertical position.
