To provide a pillar for fixing a gardening support column which can obtain a stable support without wobbling even if one thin gardening support column is installed alone in a soft gardening land or the like without ground work Materials and gardening support posts are provided.SOLUTION: A pillar material 1 made of a polymer foam having a through hole 3 for a support is inserted and filled in a cavity 6 of a concrete block 5 in the center part, and in a through hole 3 of the pillar 1 for gardening Pierce the strut 4 and pierce the ground. By doing so, the support 1, the concrete block 5 and the ground are fixed together and the gardening support 4 is stabilized without wobbling. Since the pillar material 1 of the present invention is a polymer foam, it is extremely lightweight and workability is good.(FIG.【課題】煩雑な作業を行うことなく、地盤が軟弱な園芸地等に細い園芸用支柱を1本単独で設置してもぐらつかず安定した支柱を得られる、園芸用支柱を固定するための柱材及び園芸用支柱の固定具を提供する。【解決手段】中心部に支柱用の貫通孔3を備えた、高分子発泡体からなる柱材1をコンクリートブロック5の空隙部6に挿入充填し、その柱材1の貫通孔3に園芸用支柱4を貫通させ地中に突き刺す。こうすることにより支柱1、コンクリートブロック5、地面が一体となって固定され園芸用支柱4がぐらつかずに安定する。本考案の柱材1は高分子発泡体のため非常に軽量であるため作業性がよい。【選択図】図4
