Benefits of Proper Mulching
* Helps reduce soil moisture loss through evaporation
* Helps control weed germination and growth
* Insulates soil, protecting roots from extreme summer & winter temperatures
* Can improve soil biology, aeration, structure and drainage over time
* Can improve soil fertility as certain mulch types decompose
* Inhibits certain plant diseases
* Reduces the likelihood of tree damage from mowers and string trimmers
* gives planting beds a uniform, well-cared-for look
However, Improper Mulching May Cause Problems
* deep mulch on wet soil can stress plants and cause root rot
* Piling (volcano style) against the trunk of trees can stress stem tissues and may lead to development
of insect & disease problems or stem girdling roots
* Thick blanket of fine mulch can become matted and may reduce the penetration of water and air
