PROBLEM TO BE SOLVED: To provide a three-dimensional group planting tool that is inexpensive, simple in constitution, and simple in handleability, but show high position selection freeness for planting with high stability on installation, and to provide an efficient three-dimensional group planting method using the three-dimensional group planting tool. SOLUTION: The three-dimensional group planting tool (1) comprises culture soil-holding sheets selected from nets, nonwoven fabrics or their combined double-layered sheets, which are opened on both of the upper faces and the bottom faces to form an almost truncated pyramid and the culture soil-holding sheets are made readily incision-formable at any arbitrary position.
