As you travel around campus you will notice a raised "ring" at the outside radius of our mulch rings. This serves many purposes. This ring helps retain moisture in the root zone of newly planted tress, forming a dish. It also helps protect our trees from the dreaded disease "Lawn Mower Blight." In other words, it acts as a deterrent to mowers and other equipment from bumping into the fragile trunks of our campus trees.
Forests floors are full of leaves, branches that have fallen from trees, and rotting stumps. The forest makes its own mulch, but when we keep our yards tidy, we often pick up these items and deprive our trees of natural organic nutrients. Mulch can replace those nutrients and make your yard look great! Besides, you need an excuse to go outside anyways!
