Composting and Gardening


Home Composting is a great way to reduce waste, recycle your yard debris and help your garden. Composting is a naturally occurring process where organic material (yard materials and vegetable wastes) is broken down into an excellent soil enhancer & mulch. Mixing compost into soil improves the soil's texture, and increases its ability to hold air and water. By reducing evaporation, composting allows your landscaping to use less water.
