PROBLEM TO BE SOLVED: To provide a seedling-raising medium capable of sufficiently supplying fertilizer components required for taking roots after transplantation to a planting field or the like, hardly causing temporal change of the contained fertilizer components, and hardly causing barrier to growth when raising the seedlings; and to provide a method for cultivating the plant by using the medium. SOLUTION: The seedling-raising medium is obtained by using granular fertilizer containing a urea-aliphatic aldehyde condensate as a fertilizer component, and having a particle diameter regulated within a specific range, and mixing the granular fertilizer with a medium base material (a water-holding material). The method for cultivating the plant uses the medium. COPYRIGHT: (C)2006,JPO&NCIPI
