A while back I posted an article about the dreaded "Mulch Volcano" and how deep mulch can lead to excess moisture in the root zone, which can stress the plant and cause root rot.  Plus piling mulch high against the trunk or stems of plants can stress stem tissues and may lead to insect and disease problems or that mulch piled high against the trunks of young trees may create a habitat for rodents that chew the bark and can girdle the trees.

Let me now recommend what we at EnviroColor consider proper mulching techniques.

• Inspect plants and soil in the area to be mulched. Determine whether drainage is adequate. Avoid placing mulch in drainage ways, because it may wash away or act as a dam, reducing water flow.  Determine whether there are plants that may be affected by the choice of mulch.  Most commonly available mulches work well in most landscapes.
• If mulch is already present, check the depth.  Do not add mulch if there is a sufficient layer in place.  Rake the old mulch to break up any matted layers to refresh the appearance (Top spray with EnviroColor® to refresh color if desired). 
•  If mulch is pile high against the stems of tree trunks, pull it back several inches so that the base of the trunk and the root crown are exposed.
• Organic mulches usually are preferred to inorganic materials due to their soil-enhancing properties.  If organic mulch is used, it should be well aerated and, preferably, composted.  Avoid sour smelling mulches.
• Composted wood chips can make good mulch, especially when they contain a blend of leaves, bark and wood.  Fresh wood chips can also be used around established trees and shrubs.  Avoid using non-composted wood chips that have been piled deeply without exposure to oxygen.
• For well-drained sites, apply a 2 - 4 inch layer of mulch.  If there are drainage problems, a thinner layer should be used.  Avoid placing mulch against the tree trunks.  Place mulch out to the tree's drip line or beyond.

Remember:        If the tree had a say in the matter, it's entire root system (which usually extends well beyond the drip line) would be mulched.
