Mulch is plant/animal material, usually waste from arborist trees, leaves, green waste, , or other "outside" organic materials that have been gathered and processed through a mulcher. Masterton Mulch has two blends of mulch. One for commercial applications, such as vineyards, commercial gardens, and farms for animal bedding. It contains microorganisms that are good for your garden; the digestive system for plants.
When applied in the Autumn, the mulch rots down adding nutrients to the soil.
