Description

Revitalize Your Soil

Certified Organic Spent Mushroom Compost (COSMC) is a premium, nutrient-rich soil amendment designed to improve soil health, fertility, and structure across a wide range of crops and landscapes.

This organic compost is a finely balanced mixture of straw, peat moss, cottonseed meal, mined gypsum, mined lime, and other natural ingredients.

Key benefits include:

  • Improves Soil Composition: Loosens heavy soils and enhances aeration while helping sandy soils retain moisture.
  • Boosts Fertility Naturally: Provides humus, organic matter, and light fertilization to support vigorous plant growth.
  • Enhances Water Efficiency: Increases water-holding capacity, reducing the need for frequent irrigation.
  • pH Balancing: With a natural pH in the range of around 8.0–8.3, Mushroom Compost can help neutralize acidic soils and serve as a sustainable alternative to lime.
  • Versatile Use: Ideal for amending planting beds, vegetable gardens, topdressing lawns, and as a sustainable alternative to synthetic fertilizers.

Certified Organic Spent Mushroom Compost is available wholesale to businesses by the cubic yard. 15 cubic yards minimum.
