If you are looking to redo your landscaping this year before the heat of summer arrives, there is one thing you cannot do without — mulch. Mulch is any type of material that is laid out as a covering over soil. It is not only used to protect the soil, but it protects the foliage nearby. For home landscaping, most homeowners prefer to use wood mulch. A layer of mulch provides many benefits and can be used around shrubs, bushes, and trees. It can also be used as a soft surface for a playground.
