Best Results: For best results and to reduce weed growth, install rock around 3" - 4" 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 1 1/2" rock, the minimum recommended depth would be 3" deep. Going less will likely show the bare ground beneath the rock. You are welcome to place rock deeper than the minimum recommended.

Notice: Rocks do not come clean. They may contain dust, small amounts of crushing fines, or some dirt stuck to the rocks. This is all due to the crushing or screening process. The images used are normally of the rocks after they have been cleaned off to showcase what the rocks will look like after rain, sprinklers, etc has cleaned them off. It is best to install rocks first, then rinse any dust or dirt off once installed.
