The Kiyozumi Park’s trees,especially pine trees, are guard by traditional worm guard system using the Japanese rope winding around the tree stems. The worms enter in the rope from autumn to winter for warming in the rope preventing the cold season. The gardeners take off the winding ropes at the spring and burn them quickly worms in the rope. Thus trees are kept safely from the worm damage. I love this way for its artistically beautiful knotting.
