Mushroom compost can supply nutrients and increase the water-holding capacity of the soil in lawns, gardens, and container plants. Mushroom compost is a type of slow-release, organic plant fertilizer. Our compost is made by mushroom growers using organic materials such as straw, sawdust, and horse manure.

Used with care, mushroom compost also can be used as a mulch around perennials, trees and shrubs. For flower beds and vegetable gardens, till about three inches of the compost into the top six inches of fairly dry garden soil.
