FAQ

What Is Spent Mushroom Compost?

Spent Mushroom Compost (SMC) is the organic material left over after commercial mushroom cultivation. During the mushroom-growing process, a specially prepared substrate (a mix of organic materials like straw, poultry and horse manure, gypsum, and other components) is used to support mushroom growth. Once the mushrooms have been harvested and the substrate is no longer suitable for growing more mushrooms, it becomes "spent" and is referred to as Spent Mushroom Compost.

What Can Spent Mushroom Compost Be Used For?

Spent Mushroom Compost improves soil structure, fertility, and water retention in various gardening and landscaping applications. It's ideal for enriching vegetable gardens and flower beds, where it promotes healthier plant growth and more vibrant blooms. Additionally, Spent Mushroom Compost can be used as a mulch to suppress weeds and retain moisture, making it a valuable resource for sustainable gardening.

Is Spent Mushroom Compost Acidic?

Spent Mushroom Compost has a pH of 6.3 to 7.5 and is generally considered neutral to slightly alkaline. The exact pH of Spent Mushroom Compost can vary depending on the materials used in the composting process and how long it has aged. While it is generally not acidic, it's always a good idea to test the pH if you have specific plants that require a particular soil pH.

How Do I Install Spent Mushroom Compost?

How Often Should I Use Spent Mushroom Compost?

Once or twice per season is usually preferred depending on the soil type and plants to be grown. Application in Spring and Autumn is usually the norm although it can be used all year round as a soil improver. Regular but not excessive use is the key to avoiding nutrient imbalances

Can I Use Spent Mushroom Compost With All Plants?

Spent Mushroom Compost is suitable for most plants, including vegetables, flowers, shrubs, and lawns. However, plants that prefer very acidic soil, like blueberries and azaleas, may not thrive as well with SMC due to its neutral to slightly alkaline pH.
