If working an area with poor or eroded soil something must be done to improve the soil so plants will grow. A great tip is to use about 50% organic matter and 50% native soil, mix it together, put it around the rocks, then plant Thyme or other creeping plants. This will help the plants to establish themselves. Don't put organic matter under the rocks because over time it will allow the rocks to sink.
