A Little Monterey Mushrooms® Magic in Your Garden

ATTN: Our California and Florida farms have discontinued their spent mushroom compost program. However, if you're located near Madisonville, TX; Loudon, TN; Princeton, IL; or San Miguel de Allende, MX; occasionally our farms have excess spent compost that the public is invited to use in gardening and landscaping projects. A pickup fee may apply. 


Gardening is good for the soul. There’s nothing quite like having your hands in the dirt and the sun on your back.


Spent mushroom compost is great for home gardens, lawns, and areas where the native soil is nutrient-poor. However, it contains high salt levels and, for many home projects, it will need to be further composted or amended. Our spent compost is typically made up of wheat straw, stable bedding, sources of nitrogen, and other organic materials based on the regional resources available.
