From the Garden Channell:
‘Mulch’ is a protective layer of material that is spread 3-6 inches deep on top of exposed soil between plants. Mulch is by far the best way to preserve the water in your soil and can be a very effective way of feeding your soil and regulating growing temperatures. Mulch can be almost anything: straw, grass clippings, corn cobs, river stones, pea gravel, chipped bricks, bark chips, leaves, peat moss, seaweed, wood ashes, sawdust and so on.
Nature abhors uncovered and exposed ground. Walk out into nature and look down. In a healthy ecosystem you will find very little, if any, bare ground. Nature will always try to cover soil with either plant growth, decaying matter or even inorganic matter. Trees drop their leaves and cover the floor of a forest for example. You’ll want to imitate the same process in your garden.
