Mushroom Compost


Our mushroom compost is a great soil amenity. 

Benefits of using Mushroom compost in the landscape

  • New plants will establish faster and grow more vigorously.

  • The structural characteristics of mushroom compost are ideal for loosening and improving heavy soils.

  • The particle size is quite favorable for improvement of soil's physical properties.

  • As an amendment, mushroom compost also supplies needed nutrients in a form particularly suited to most groundcovers

  • When used as a mulch, it will upgrade the soil condition and provide nutritional benefits to existing beds.

  • Mushroom Compost can be used for seeding grass and sodding, giving the seed/sod a quick start for a faster established lawn. (After grading the site, top dress lawn area with 1.5" mushroom compost for seeding and 1" for sodding. Seed directly into compost or lay sod.)

Physical Properties of Mushroom Compost

  • The availability of soluble nitrogen in mushroom compost is relatively low, which means no burn, but total nitrogen is present in such a form that it will be released as further decomposition takes place. Phosphate, potassium, calcium and magnesium are quite high. Salinity is well below that of typical manure. The micro-element content is good for copper, high for zinc, manganese and iron, and slightly low for boron. Organic content is approximately 66% by weight. The particle size is quite favorable for improvement of soils physical properties.

  • As a soil amendment when mushroom compost is employed in pre-plant bed preparation, it should not be necessary to apply any further fertilizer or amendments providing applied quantity is 5-10 cubic yards per 1,000 square feet (approximately 2-4 inches). Thorough mixing to a depth of 6" should be done. The compost should not be used as a growing medium but as an amendment for the improvement of existing low fertile soil. Addition rates should not exceed 20% by volume.
