A flexible structure for reinforcing earthworks comprises a porous membrane with grass rooted therein and may also include a layer of fertile material below the membrane. The membrane may be formed of a fibrous synthetic material such as polypropylene. The flexible structure may overlay or underlay a perforate wall of a rigid container filled with a fertile material. The containers may be used to provide support for vegetation over the surface of steeply inclined earthworks.
