The difference between river rock and landscaping rocks is size, smoothness, and use. River rocks are smooth and flat, as if polished by water, and come in diameters between 1 and 8 inches. Landscape rock can vary in size from small pea gravel installations to car-sized boulders. However, landscaping and river rocks are interchangeable in many situations. River rock is best for pathways, walkways, garden bed mulch, water features, and planting accents, while small landscape rocks can serve as a walkway base, gravel playground areas, and filler between pavers.

As a base, you should use a fertilizer with a 5-5-5 NPK ratio (5% nitrogen, 5% phosphorus, and 5% potassium). You may need a different ratio depending on what your soil is lacking, but a soil test can help determine the perfect amount.

Using sand under stepping stones can be beneficial in certain situations. Sand can help level the ground and provide stability for the stepping stones, especially if the ground is uneven. It also allows for minor adjustments during the installation process. However, sand may not be the best choice for all environments. In areas with high foot traffic or heavy rain, sand may wash away or become displaced, leading to an uneven surface. In such cases, a more stable base material like gravel or crushed stone is preferable. Consider your specific landscape conditions before deciding whether to use sand under stepping stones.

Grass varieties such as tall fescue, zoysia, Bermuda, Bahia, and centipede grow best in sandy soil. These types of grass are drought resistant, so they help retain water and nutrients more easily. Consult a local lawn care company to determine the best type of grass to plant in your sandy lawn.
