The benefits trees can gain from mulching

There are many times people will call with questions about what they can do to help their trees grow better (cultural practices) or what they can use to help keep weeds out of the garden. One of my suggestions is almost always mulch. Now, it should be stated that mulch is just one component of good cultural practices in landscaping and gardening; especially with trees. However, mulching is definitely an important one.  
    What benefits does mulch provide plants?
    Mulch helps to moderate soil temperatures, helps maintain even soil moisture, minimizes soil erosion and runoff, reduces weeds by minimizing weed seed germination, keeps lawn mowers and weed whips away from trunks of trees and other woody ornamentals preventing mechanical damage, and, overtime, adds organic matter back in to the soil as mulches break down.
