Boost Your Garden and Soil Health with Organic Mushroom Compost

At River Valley Ranch, we produce high-quality organic mushroom compost that is perfect for enriching soil and promoting plant growth.

Mushroom compost, also known as spent mushroom substrate, is the byproduct of the mushroom growing process. River Valley Ranch's mushroom compost is comprised of 80% composted stable bedding and 20% Canadian sphagnum peat moss. Its pH level is about 6.3, and it also contains nitrogen (about 2.5%) and calcium. Our compost is pasteurized, weed-free, and high in organic matter.

Benefits of Using River Valley Ranch Mushroom Compost

Adding mushroom compost to the soil is known to improve soil structure, tilth, water holding capacity, and overall plant health. Perhaps its greatest benefit to the soil is that the compost increases the soil's microbial activity for healthier root development. When tilled into heavy clay soil, it can help loosen the soil and when tilled in sandy soil, it can aid in moisture retention. Applying it as a mulch (2-3 inches thick) keeps new plantings cool, conserves water, and improves soil biology, as well as limiting weed growth.

How to Use Organic Mushroom Compost

Our compost is available in both bagged and bulk form. One bag of compost covers approximately 10 square feet, 2-3 inches deep. For bulk purchases, one cubic yard covers 100-120 feet, 3 inches deep. When using our compost as a mulch, we recommend applying it 2-3 inches thick for best results.

If you're looking to boost your garden's health and promote plant growth, River Valley Ranch's mushroom compost is an excellent choice. Come visit us at our farm store in Wisconsin or give us a call to learn more about how our compost can benefit your garden!
