It’s application or use is only limited by your imagination. They offer texture and colour to gardens, they sit well up against a path, around gardens and around plants in pots to help retain moisture where bark or mulch is not wanted. It can be used as a topping for pathways and driveways, it depends on your desired outcome or experience. River stones are heavier than standard garden pebbles and therefore don’t lift and move easily, this makes them great to use around the garden if you have pets that tend to dig up your mulch.
