PROBLEM TO BE SOLVED: To provide a gardening-container bottom sheet formed with a minimal amount of material even when used for a large scale of a gardening container such as a flowerpot or a planter to reduce material costs, and flatly formed to also reduce forming costs. SOLUTION: The gardening-container bottom sheet is obtained by forming a pair of trapezium-shaped flat plate parts 11 and a pair of triangular flat plate parts 12, and is assembled by folding the trapezium-shaped flat plate part 11 and the triangular flat plate part 12 to hold a male-side holding part 31 to a female-side holding part 32 so as to form a hollow and nearly triangular shape. A support plate part placed at the bottom wall of the gardening container comprises a long edge part 21 and a short edge part 22. COPYRIGHT: (C)2007,JPO&INPIT
