Definition as written by Terry:
An inorganic mulch differs from an organic mulch in that it is typically made from an inert material - some are synthetic, such as plastic sheeting, landscape fabric, and pelletized bits of rubber tires; others are natural, including many types of rock.
Although they are inert the synthetic mulches can degrade over time, especially when exposed to sunlight. For that reason, as well as aesthetics, many gardeners will cover the synthetic mulches with an organic mulch such as shredded bark
