How to repurpose spent mushroom substrate for gardening
Spent mushroom substrate (SMS) is the material left behind after you’ve harvested your mushrooms. It may look like waste, but it is full of potential and can be reused in your garden. Here are some ways to repurpose spent mushroom substrate for gardening:
Soil Amendment or Soil Conditioner
Spent mushroom substrate is high in organic matter, making it ideal for use as a soil amendment or soil conditioner. It adds organic matter and improves the structure of the soil. It also provides a few nutrients, enhancing soil fertility and promoting healthier plant growth.
Mulch
Mulching involves spreading a layer of spent mushroom substrate around the base of plants or over garden beds. This practice offers several benefits, including moisture retention, weed suppression, and soil enrichment. As the substrate breaks down, it gradually releases nutrients into the soil. Mulching also helps conserve water by preventing evaporation from the soil surface and reduces the need for chemical fertilizers.
Composting
Spent mushroom substrate can be composted, adding valuable nutrients and organic matter to your compost pile or bin. This process helps to improve the quality of your compost, which can then be used to amend your garden soil or fertilize your plants.
New Mushroom Beds
Spent mushroom substrate can be reused to create new mushroom beds for continued cultivation. This involves mixing the spent substrate with fresh organic materials, such as straw or sawdust, and inoculating it with new mushroom spawn. Proper sterilization and pasteurization before reuse are essential to eliminate any potential contaminants.
It is important to note that spent mushroom substrate may contain pesticides or other contaminants. Before reusing the substrate, ensure that it is properly sanitized and free from any harmful substances. Additionally, some plants and garden vegetables are sensitive to high salt content in soils, so avoid using fresh spent substrate around those plants. Weathering the substrate for six months or longer can help reduce the salt content and make it suitable for use in all gardens and with most plants.

To ensure the safety of your compost, it's recommended to start with a hot compost process, heating your compost pile to 70°C for at least a few days to kill any hazardous bacteria or weed seeds.
Gardening and Agriculture
SMS can be used as a soil amendment, adding organic matter and improving soil structure and nutrition. It can be spread on newly seeded lawns to protect seeds from birds and retain moisture in the soil. When using SMS in gardens, it's best to allow it to weather for at least six months before applying it in spring or summer as mulch. SMS is also an ingredient in potting mixtures sold in garden centres.
Donating to Farms
Instead of disposing of SMS, consider donating it to farms, which may repurpose it for growing mushrooms or compost. Some farms may also experiment with using SMS as animal feed, particularly in chicken and calf feed blends.
Burying
Burying SMS in the ground is another disposal method. However, it's important to ensure that it's done responsibly and in a suitable location to avoid potential environmental concerns.
Reusing for Mushroom Growth
SMS can be reused to grow another batch of mushrooms, especially if you have a large amount of spent shiitake blocks. These blocks can be broken up, re-sterilized, and the organic material can be used to grow new shiitake mushrooms.
