River Rock

The term "river rock" refers to a diverse group of rocks that have been worn and rounded by the action of moving water. River rocks are most often found on beaches and in stream beds and can come in a range of sizes, colors, and textures. It is a common rock available in sizes from 1 inch up to 6 inches. River Rock can be used to mulch around flower beds, vegetable gardens, trees, pathways, and buildings. The weight of the stones and the way they block sunlight discourages weed growth. At Nix Landscape Supply, we offer varying sizes:

1 inch

1.5 inches to 2.5 inches

4 inches to 6 inches

River Slicks -- sometimes called creek rock or river rocks --are mined from ancient river beds. Earthquakes over the years can change the course of a river leaving these rocks just under the surface. Consider using these rocks for waterfalls, ponds, sidewalks, garden walls, fire pits or fireplaces.

Mexican Beach Pebble


Mexican Beach Pebbles are 100% naturally formed decorative rocks originally found in Baja, Mexico. Their shape and texture come from the erosion of the stones from the cliffs along the beaches. The energy of the waves and the sand polished and smoothed the pebbles, giving them a smooth and unique shape. Mexican Beach Pebbles landscaping is the perfect solution to almost any outdoor improvement project you are considering that requires small decorative stones. At Nix Landscape Supply, we offer three sizes:


1/2 - 1 Inch

2 - 3 Inch

3 - 5 inch.

Black Lava Rock

Volcanic Lava Rock is very porous and weighs less than half that of other landscape materials making it easy to transport and spread. Lava Rock insulates the soil from heat and cold. Studies show that lava rock is more effective in retaining moisture in topsoil than wood mulch products. It helps regulate moisture in the ground and will not rot, decay, or be subject to color fade like wood mulches, making it a permanent mulch replacement.

White Marble Rock

Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. The white marble rock is a popular landscaping stone and is typically used as a decorative element in flower beds and similar areas with high visibility.  Due to the nature of natural products, physical properties will vary (size, color, etc). Available for pick up or delivery.

As with Black Lava Rock, Red Lava Rock is lightweight and effective at retaining moisture. Gardeners and garden architects use lava rocks for decorative and water retaining purposes. The stones can be placed on pathways to give a colorful design effect, or used as border decorations. Smaller lava rocks are used as mulch to collect water and to avoid erosion.

Moss Boulders

Moss rock is a type of sandstone or flagstone, usually with brown and red undertones, that is covered with moss. It is commonly used within garden pavers, water features, and landscape walls. Over time, more moss will develop on rocks that are properly maintained and positioned. Moss boulders are a beautiful addition to any landscape. At Nix Landscape Supply, we carry small, medium, and large boulders.

3/4-Inch to 1-Inch Gravel

Construction-grade gravel that is available in three-quarters and one-inch sizes.  This gravel works well in driveways, field lines, and base layers.

Pea Gravel is a popular choice for walkways and landscape cover and consists of naturally rounded, pea-sized pebbles that are easy to work with.  Pea Gravel works well in French drains and other drain applications.

Black Star Gravel

Black Star Gravel is a Basalt, a very dark, hard stone that forms from cooled magma. In Texas, it is found around the Chisos Mountains, Fort Davis, Guadalupe Peak, and down along the Rio Grande.  It is extremely durable, functional, and aesthetically pleasing in landscaping. It makes a beautiful accent under fountains and statuary. Black Star Gravel is also used for walkways and anywhere an upscale look is desired.

Road Base.jpg

Road Base is a mixture of stone and sand with varying sizes of particles that allow for solid compaction. Road Base is an excellent choice when using asphalt or concrete is cost-prohibitive.  

Decomposed Granite.jpg
Decomposed Granite

Decomposed Granite (DG) is made up of small granite pieces, typically 1/4-inch or smaller.  It is derived from granite via its weathering to the point that the parent material readily fractures into smaller pieces of weaker rock.  It is used to pave patios and driveways, and provides a natural look of tan and brown colors.  

Crushed Concrete.jpg

Crushed Concrete is recycled concrete that has been ground up into smaller particles.  Crushed concrete is an affordable and eco-friendly material that can be used on driveways, walkways, drainage areas, and as a base layer.

Crushed Asphalt, also known as asphalt millings, is considered recycled asphalt pavement — essentially, they're former asphalt projects being crushed into gravel. Nix Landscape Supply carries high-quality, cost-effective recycled asphalt that is properly crushed and screened.
