A simple but effective tool to help you secure a bendy tree without causing the damage that wires or ropes will cause. Use stakes placed near the edge or outside the tree drip line and run a wire or rope to this sling. Adjust as needed, remove when tree is capable of supporting itself in moderate winds.
It is important to allow the tree to move in the wind so that it can build up it's core strength. This strap/sling will allow for that movement.
