PROBLEM TO BE SOLVED: To provide a seed-housing medium for housing the seeds of a plant or the like in a substrate material, which enables stable germination and growth irrespective of the material quality of cover film or the like, and the environment of a medium. SOLUTION: Since the seeds 5 and a polymer absorbent material 6 are housed together at a seed-housing part provided in the substrate material 2 and the seed-housing part is sealed with the cover film 7, the polymer adsorbent material 6 adsorbs water in soil on being buried in the soil to increase its volume, and the cover film 7 can surely be destroyed to increase the germination rate of the seeds 5.
