ABSTRACT The invention relates to a multiple pot comprising individual pots interconnected by connector portions so as to be capable of being pulled individually from the multiple pot or in rows. The multiple pot is used to raise and transplant seedlings of plants. The invention also relates to a method of manufacturing the pot. The pot is designed especially to promote growth of roots across the side walls of the individual pots after transplantation. Also, the resistance encountered when the multiple pot is unfolded is reduced. Further, the individual pots are uniform in size. These features arise from special connector portions, which are formed by applying a waterproof paste discontinuously between two adhered films. Furthermore, a water-soluble paste is not applied around the edges of the individual pots created when the multiple pot is unfolded. The multiple pot is fabricated by continuously carrying out three steps. In the first step, the waterproof paste is applied in a given pattern while continuously pulling out two continuous thin films. In the second step, folds are formed in the belt resulting when the two thin films are adhered together and the belt is folded in a zigzag fashion to form layers. In the third step, the water-soluble paste is alternately applied to the front side and the rear side of adjacent layers of the belt and between the folds. Then, the belt is refolded, and pressure is applied to it to stick together the folded layers.
