Summary:PROBLEM TO BE SOLVED: To provide the culture medium for the greening a rooftop and a ground part of a building requiring less time and labor for cultivation and facilitating the water control without elution of waste water, by finding out the optimum physical properties and grain size of a solid culture medium for greening. SOLUTION: This culture medium for greening the rooftop and ground is characterized in that the culture medium is composed of a granular pumice having a smaller bulk specific gravity than that of usual soil and 0.3-0.8 bulk specific gravity of pumice. The granular pumice preferably has 0.1-1.0 cm/s saturation water permeation coefficient and 5-60 cm/s air permeation coefficient in a dry sample and a wet sample.
