Natural Black Slate is a characteristic plate-like structure, and shallow metamorphic rocks are formed by slight metamorphism of clayey, silty sedimentary rocks or medium-acid tuffaceous rocks and sedimentary tuffs. Slate, as a natural stone, has inherent properties that make it an ideal decorative material.
Creating a Black Crushed Slate walkway with supplies from a garden store is simple. First, clear the path for your walkway, removing all grass, weeds and rocks. Use landscape fabric or landscape plastic as a barrier between the soil and the crushed slate. The fabric or plastic prevents weeds from growing up through the crushed slate. Adding edging to the path helps to contain the slate. Depending on the color of the material you use, the walkway can provide a nice contrast to the grass and plants in your yard. Straight walkways also provide clean lines, giving your lawn a neat and tidy appearance. Another idea is to add larger pieces of slate in a contrasting color as stepping stones on the path.
For decorative borders to flower beds, shrubs and trees, apply crushed slate alone or mixed with other decoration stone. The material is good for drainage and helps to keep weeds from growing. The subtle hues of the slate can also be complementary to the colors of the vegetation it surrounds. Other benefits of slate borders include keeping dogs from digging and urinating around plants. Crushed slate borders also discourage foot traffic near your plants.
