PROBLEM TO BE SOLVED: To provide a greening frame made to match the surrounding environment by building in order to stabilize a slope to very simply green the whole surrounding surface of a certain existing stable beam. SOLUTION: The greening frame A comprises a pair of right and left porous side plates 1, coupled lever members 2 attaching both ends to the upper edge sides located on a required interval in the longitudinal direction of both side plates and prop lever members 3 for expanding the side plates projected inward to each other by mounting them to the lower parts of both side plates, and a greening spray is sprayed to green after the greening frame has been fitted to the existing stable beam.
