Abstract: The present invention relates to an improved capillary mat for water plants. The mat includes a lower piece of the air bubble type material. This provides a support base to be laid in a tray leaving space for a water reservoir between the air cells. In accordance with the present invention, instead of using a fiber type material for the top piece on which the plant is rested, a piece of solid sheet plastic material is used. The sheet of plastic material has a number of holes therein. The plastic sheet material is only sealed to the bubble packed material at certain places so that water can travel by an adhesion type effect in the free space between the plastic sheet layer and the air bubble material and exit through the holes in the sheet to the plant pot. The center structure is of waterproof material. The plastic sheet layer will not become discolored and can be wiped clean if any unwanted material deposits on top of it.
