Volcanic Red Lava Rock for Gardening, Red Basalt Garden & Palisade

Once Lava Rock starts to harden it will turn various colors. The color of lava rock depends on the peak temperature the lava flow reaches, as well as what impurities are in the rock.

Colors can include black, red (Shown here), gray, brown, metallic silver, pink, and green. Some lava rock has peridot (olivine) in it which are beautiful olive colored semi-precious crystals that once they weather and break apart create a beautiful green sand.

Carroll’s Building Materials carries two colors of Lava Rock, Black and Red. Shown here is our Red Lava Rock, well known for its deep red color.

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 better 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.
