PROBLEM TO BE SOLVED: To provide a vegetative base concrete capable of smoothly greening a slope by bringing up grass brought up from seeds in borrow filling holes filled with the borrow in the vegetative base concrete in the direction close to the vertical plane to the horizontal plane as much as possible to finely bring up the grass. SOLUTION: The vegetative base concrete 1 is formed by hardening excelsior tips with cement, at the same time, the borrow filling holes 12 to be filled with the borrow passing through between both up and down surfaces is penetrately provided, the vegetative base concrete is used for the greening slope A on which it is laid, and since the borrow filling holes 12 are inclined and are directed upward of the vertical direction to the slope, the seeds in the borrow B are satisfactrily brought up toward the direction close to the vertical plane as much as possible, accordingly the greening of the slope A can be surely executed within a short period of time.
