The present invention relates to rooting structures for receiving rooting plugs comprising seedlings, young plants or plants. Specifically, the present invention relates to rooting structures (1) having a strip-shaped geometry that is deformable from a flat state wherein the rooting structure (1) generally extends in a flat plane to a curved state wherein the structure surrounds a volume for receiving a rooting plug (21), the strip-shaped geometry having, in its flat state, a pair of mutually opposite short side edges (11, 12) and a pair of mutually opposite long side edges (13, 14), as well as a bottom surface (6) forming, in its curved state, a convex side, and a top surface (4) forming, in its curved state, a concave side, the top surface has a relief pattern extending between the pair of mutually opposite short side edges (11,12) extending between the pair of mutually opposite long side edges and a generally straight top edge (17) having a protrusion (18) extending upwardly at a long side edge (14) of the strip-shaped geometry.本發明係關於用於接收包含苗、幼齡植物或植物之發根插塞的發根結構。特定言之，本發明係關於發根結構（1），其具有可自平整狀態變形為彎曲狀態之條形幾何結構，在該平整狀態中該發根結構（1）大體上在平面中延伸，在該彎曲狀態中該結構圍繞用於接納發根插塞（21）之容積，該條形幾何結構在其平整狀態下具有一對相互相對之短側面邊緣（11，12）及一對相互相對之長側面邊緣（13，14），以及在其彎曲狀態下形成凸側之下表面（6）及在其彎曲狀態下形成凹側之上表面（4），該上表面具有在該對相互相對之短側面邊緣（11，12）之間延伸之凹凸圖案，該對短側面邊緣在該對相互相對長側面邊緣之間延伸，及大體上直線形頂部邊緣（17），其具有在該條形幾何結構之長側面邊緣（14）處朝上延伸之突起（18）。
