Do trees grow better with mulch?

Research has proven that, over time, a mulch ring placed 3 to 6 feet around the tree can almost double the growth rate of the tree. Mulching decreases competition from the grass. Grass robs water and nutrients from the tree’s root development and delays its establishment.
