Depending on the size of the river rock and the density of your soil, add woven landscape fabric or sand under river rock. The extra layer will ensure your river rock sits evenly and doesn't create puddles or uneven areas throughout the design. In some cases, nothing is necessary beneath river rock, but be sure to speak with a landscaper to keep your landscaping looking sharp.

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.

While they’re popular and have a lot of pros, the cons of river rocks include the following:

• River rocks don’t break down or provide nutrients to plants. 

• These stones can get hot and scorch nearby plants. 

• River stones may heat the surrounding soil to inhospitable temperatures. 

• Rocks can block rainwater from seeping into the ground if installations are too thick or tightly packed.

Most downsides occur when using river rock as mulch in gardens and flower beds. However, you can still incorporate river rocks into your landscape as long as you use them in the correct ways.
