The side wall 3 is composed of plural rod-shaped side wall members 31, a lower part-supporting member 32 for supporting the lower part of the side wall members 31 and an upper part-supporting member 33 supporting the upper part so that slits 3a as passage parts for roots may be formed between the side wall members 31. A culture medium such as smoked charcoal is then filled in the nursery pot 1 and a seed of a nursery stock is sawn following immersing the pot 1 in a liquid fertilizer.
