PROBLEM TO BE SOLVED: To provide a greening device by liana, applicable to any liana of climbing root type liana or winding type liana, and even if a foothold of construction is on any side either of the front or the back of a greening surface, enabling easy performance of construction and maintenance management from both the sides. SOLUTION: This greening device 1 by liana is set with a porous climbing aid material 2 which assists climbing of liana P. The belt-like climbing aid material 2 which is narrower than that of a lattice body 4 made by forming wires in a lattice-like form is attached in the horizontal or vertical direction of the lattice body to sew the lattice of the lattice body 4. Both the ends of the climbing aid material 2 are fixed to both the ends of the lattice body 4. COPYRIGHT: (C)2008,JPO&INPIT
