Bulk Products
Mulch, gravel, soil and other products sold by the cubic yard.
A typical mulch application is 3" deep. If you are just topping off your beds, then you could try a 1" to 2" layer.
A typical gravel layer is around 2", but keep in mind that if you are using bigger sized stones that they will be hard or impossible to spread at that thickness.
For Example: Egg Rock, River Pebbles, and River Slicks should be calculated at a 3" thickness. Creek Slicks and Mega Slicks should be calculated at a 5-6" thickness.
