The present invention relates to a supporting device capable of allowing a location of a flowerpot to be moved. The supporting device covers the upper surface of a storage member of a plant cultivation device for cultivating a plant using water, and the purpose of the present invention is to supply water to a flowerpot that is placed anywhere on the upper surface, to prevent a malfunction of a water feed means by blocking the discharge of soil from the flowerpot, and to block the inflow of dust in the air or the leaves of a planted plant by covering the upper surface of the storage member, thereby preventing the contamination of water. The purpose is achieved by comprising: supporting members which are formed in the form of a plate are placed on the upper surface of the storage member to be connected to each other and to cover the upper surface of the storage member, and comprise a plurality of holes for water supply formed on the plate to allow water to be supplied to a plant planted in a flowerpot movably placed on the upper surface and hole stopper members for covering the holes for water supply except the selected holes for water supply to prevent the inflow of dust in the air or the leaves of a planted plant into the storage member.La présente invention concerne un dispositif de support permettant de changer lemplacement dun pot de fleurs.
