部からは見えなくなっていくので美観上も良好となる。In this net 1, the net 2 is a pocket 4
It does not inhibit the elongation of the stalk of the plant grown in it, and allows the fallen leaves from the forehead and elongated plant to pass through the pocket 4, so that the accumulated fallen leaves gradually become humus, and the plant naturally ingests nutrients. And grow. Further, since the sheet material 3 is made of a material which can be used for retaining the earth and which does not hinder the elongation of the root, the pocket 4
At the same time, the vegetation base is stabilized, and as the plants grow, the roots pass through the pockets 4 and become rooted in the ground, so that greening that is closer to the natural state can be realized gradually. And
As the plants elongate in this way, the net 1 becomes invisible from the outside, so that the aesthetic appearance is also improved.
