PROBLEM TO BE SOLVED: To provide a planting container preventing freeze or high-temperature drying of soil by performing heat insulation or heat radiation such that cold heat coming from a side face of the planting container or high-temperature heat by the irradiation of sunlight is not transferred to the planting soil inside the planting container.SOLUTION: A planting container includes: an inner wall provided between an outer wall and a soil space of the planting container; a gap serving as a movement passage allowing the vertically movement of air, provided between the outer wall and an inner wall; a communication port communicating outside air and the gap, provided at the lower end of the outer wall; and opening parts opening to the outside air, provided at the upper end of the gap. This configuration allows air to move upward or downward by cooling air or a temperature rise by high-temperature heat, and prevents transmission of the cold heat or high-temperature heat to soil by discharging it to the outside air. |
