Lava Rock is a unique way to provide the dark rich bed color found from nutrient rich soil or dark mulch.
Our lava Rock is screened to remove any red tones, and provide a clean consistent black rock that is ideal for flower beds, walkways or areas traditionally reserved for mulch or bark.
For best results and to reduce weed growth, install rock around 2″ – 3″ deep over top of quality commercial grade weed barrier.
Recommended Depth Rule:
The rule of thumb with rock is to install a rock atleast twice the size of the rock not going any less than 2″ deep when using small rocks. With a 3/4″ rock, the minimum recommended depth would be 2″ deep. Going less will likely show the bare ground beneath the rock. You are welcome to place rock deeper than the minimum recommended.
