PROBLEM TO BE SOLVED: To provide a vegetation base that can green the places drastically dried places in artificial constructions, e.g., roof tops, verandas or steep roofs of multistory buildings by retaining moisture on these parts without weight increase in soil due to thickenss increase in the soil layer. SOLUTION: Moisture-retaining balls prepared from aggregate or potting compost are mutually connected to form blocks whereby potting plates are produced. Then, the plates are placed in the water storage vessel, the water necessary for plant growing is stored in the vessel, while the drainage is carried out by passing through the gaps between the vessels to achieve well-balanced moisture retention/drainage.
