An artificial soil composition and a method of growing vegetation on a sloped surface, especially a cut rock surface are disclosed. The artificial soil composition includes peat, granular soil, sewage sediment formed by the treatment of urban waste for example and pulp sludge formed by the de-watering of fibrous material and is a byproduct of the manufacture of paper from wood pulp. The artificial soil composition is applied over a meshing which is secured over a sloped cut rock surface. Plants are grown in the layer of artificial soil. Experimentally, the artificial soil is shown to have an increased adhesion to the inclined surface compared to natural soil, promotes plant growth and retains water to a greater extent than natural soil but does not cause an environmental hazard resulting from the leaching of compounds in the run-off water. The preferred concentrations of the constituents by weight are: peat (10-30%) granular soil (10-30%) sewage sediment (40-60%) and pulp sludge (25-44%).
