PROBLEM TO BE SOLVED: To provide a method for raising seedlings which can prevent the root portion of a seedling being raised from coming into contact with the inner surface of the seedling raising pot and the seedling protruding downward from the seedling raising container from being entangled with the outer peripheral portion of the seedling raising pot. SOLUTION: In a method for growing seedlings in which a seedling raising soil is laid in a seedling raising container 2, crop seedlings are inserted into the seedling raising container, and the root of the seedling is extended below the lower end of the seedling raising container, a predetermined seedling root is specified in the seedling raising container. An inhibitor Ob that inhibits growth in a direction other than the direction is imparted, and the inhibitor Ob is added to a chemical solution LM containing a curing agent or the like, and at least one of the inner wall surface 2c and the lower opening 2b of the nursery container is used. Alternatively, the drug solution LM shall be applied to both, and the inhibitor Ob shall be placed on the seedling raising container 2 in the drug-giving container under the addition of the drug LM, or the inhibitor Ob shall be added when the seedling raising container 2 is formed. do.
