Mushroom compost is the spent, sawdust-based growing substrate used previously for producing gourmet mushrooms. Prized for its water retention and low in nitrogen, use as a mulch or top dress to help prevent weed germination. Or spread a thin layer as an amendment to the long-term health of your soil, adding humus to rocky soils in dry climates.
