PROBLEM TO BE SOLVED: To provide a container for cultivating vegetables producing almost no invasion of roots even singly by a foam molding and endurable to repeated use without the need of combining a plurality of resins such as covering the foam molding and using together with a container made of other material, in view of the fact that a conventional container for cultivating vegetables made of polystyrene foam allows cultivation roots at the time of growth of vegetables to easily invade. SOLUTION: This container for cultivating vegetables as a polyolefin resin foam obtained by a bead method, that is, an in-mold molding method. The container considerably limits the invasion of cultivation roots by singly or combinedly adopting methods of transferring forming a net-like pattern on the bottom of a vegetable cultivating chamber, setting a belt-like surface such as R in a corner made by the bottom and a side wall and leaving traces of holes for heated steam introduction on the corner.
