Bark mulch is used as a covering over the soil where cultivation takes place or in home and public gardens.
There are a variety of reasons for using bark mulch. These chiefly include to:
- Preserve soil moisture
- Control growth of weeds
- Enhance productivity in crops
- Improve plant health in gardens
- Improve aesthetic look of the area
- Hemlock bark
Bark mulch is a preferred mulch material as it decomposes easily and enriches the soil. Where used in gardens, it creates a pleasing appearance enhancing the aesthetic values. The most popular barks for mulching are pine and cedar. The bark is either broken into coarse chips or ground to a powder.
Good quality bark mulch encourages growth of vegetation by thwarting weed growth thus reducing opposition for the plant. As a soil improvement agent, bark increases soil ventilation thereby indirectly preserving wetlands.
