The present invention provides a planting base for a wall that can be efficiently and uniformly drip-irrigated. [Solution] The ready-mixed concrete mixed with granular pumice, Portland cement and water is hardened into a plate shape, so that the implantation hole 2 opened obliquely upward with respect to the surface does not overlap in the irrigation flow direction. Three are formed as planting panel 1. A plurality of planting panels 1 are supported by the holding frame 3 to form a wall surface. A drip-type water spray pipe 4 and a diffusion cloth are provided on the top of the holding frame 3. The floret 6 grown in the seedling pot made of synthetic resin is extracted from the seedling pot and inserted into each planting hole 2. Drip irrigation from the watering pipe 4, spread the water uniformly with a diffusion cloth, and moisten the planting panel 1. Water is transmitted through the permeable planting panel 1 to sufficiently irrigate the planting panel 1 in the bottom row. Thus, since the roots of the florets 6 are settled on the permeable pumice concrete planting panel 1 with a minimum amount of water, water can be efficiently irrigated. [Selection] Figure 1【課題】効率的に一様に点滴灌水できる壁面用植栽基盤を提供する。【解決手段】粒状の軽石とポルトランドセメントと水とを混練した状態の生コンクリートを板状に固め、表面に対して斜め上向きに開口する植込孔２を、灌水の流下方向には重ならないように３つ形成して植栽パネル１とする。複数の植栽パネル１を保持枠３で支持して壁面を形成する。保持枠３の頂部に点滴型の散水管４と拡散布を設ける。合成樹脂製の育苗ポットで育てた花卉６を育苗ポットから抜き出して、各植込孔２に挿し込む。散水管４から点滴灌水して、拡散布で水を一様に拡げて、植栽パネル１を潤す。透水性の植栽パネル１を水が伝わって、最下列の植栽パネル１まで十分に灌水される。このようにして最少の水で、花卉６の根が透水性軽石コンクリートの植栽パネル１に活着するので、壁面植栽に効率的に灌水できる。【選択図】図１
