Mushroom Compost

Frey Professional Mushroom Compost can be used to improve soil conditions and optimize your flower and vegetable beds and lawn. Our compost is sourced with repurposed farmed mushroom substrate from Chester County Pennsylvania, an area long known for the growth of its high-quality mushrooms. The compost is made up of natural materials such as horse manure, bedding and straw, cocoa hulls, poultry manure, gypsum, and corn cobs. This versatile product can be integrated into the soil before planting or applied as a topdressing for established plants. Our Mushroom Compost Blend helps increase moisture retention and adds rich matter back into your soil.
