One Bag of Glass Mulch Covers How Much Ground?

Definition

• Glass mulch is typically sold by the pound, such as bag sizes containing 1, 5, 25 or 50 lbs.

Basic Formula

• According to American Specialty Glass, a terrazzo and glass recycling facility near Salt Lake City, Utah, glass mulch is usually spread at a depth of 1 inch. An industry guideline for determining coverage is that 7 lbs. of glass covers a 1-square-foot area at a spreading depth of 1 inch. Whatever the bag weight, divide by 7 to learn the area the bag's contents covers. For example, 50/7 equals 7.14 square feet.

Considerations

• Glass mulch is for decorative use, rather than the utilitarian uses other mulches serve in the landscape. Therefore, glass mulch is laid in shallower depths. Moreover, the size of the glass pieces affects coverage of the soil. Smaller particles settle and fill voids better than larger bits.
