The size of a gardening container of the present invention is a size that makes it possible to create a garden with an enjoyable landscape, and a garden with a large area can be created by combining a plurality of the gardening containers. It is possible for the container to be moved, loaded onto a vehicle, and transported by providing groove-like spaces between rails provided to the back surface of the container bottom, and inserting the forks of a transporting pallet therein or attaching a crane belt and lifting the container with a crane. The present invention has a structure in which a slope is provided to the bottom surface of the container so as to lead rainwater and sprinkler water that have fallen onto the plants of the garden created in the container toward a drain opening, and the rainwater and sprinkler water that have fallen onto the plants flow out from the drain opening, thus making it possible to plug the drain opening and accumulate water in the low portion of the container bottom. An overflow drain opening is also provided in the container, enabling drainage at a constant water level. The drained water flows to a drainage reservoir tank where the water accumulates, and the water in the drainage reservoir tank can be reused by being circulated by a pump and redistributed. As a result, the present invention can also be used indoors, as the water distributed onto plants is prevented from leaking to the exterior. In addition, by providing a combination of a drainage purification agent and a filtration tank stopper or of a purification material and a filtration tank in the container, or by purifying the rainwater and sprinkler water as the water flows through the planting soil to form a pool, plants and a pond can be created in a single gardening container, and fish and other creatures can be kept therein. A portable garden created in this gardening container or gardening pallet also makes it possible to sell and rent gardens.La présente invention concer
