Beside this, what do you put under river rocks?
River rock requires a weed barrier fabric to be laid underneath it to prevent weeds and also to prevent the rock from sinking into the soil. The average river rock bed lasts 10-15 years. Weed seeds and silt blow in and leaves and twigs fall from trees and bushes and decay.
Additionally, should I put plastic under gravel? Plastic. Plain black plastic helps the soil retain moisture. The dense plastic keeps weeds down effectively but stops air movement as well as water. This causes root rot if you have plantings in the area covered by the plastic.
In this regard, what to put under rocks to prevent weeds?
Adding underlayments between the rocks and the soil creates a weed barrier that helps prevent weed seeds from touching the soil. If you already have rocks in place, rake them away temporarily while you install the underlayments. Choose landscape fabric or black plastic as the underlayments.

It does provide a weed barrier but it also prevents the stone from sinking and disappearing into the soil below.
