Mulch offers many benefits to your soil and plants.  In addition to its decorative value; it reduces the amount of water lost through evaporation by shielding the soil from the sun’s drying rays.  It also keeps the soil cooler during the summer and acts as an insulator through the cold winter months. Mulch also encourages the activity of beneficial soil organisms and adds organic matter as it breaks down. Furthermore, mulched areas are less prone to erosion and weeds.
