Can You Compost Mushrooms?


So, can you compost mushrooms? Yes! Mushrooms are organic materials and can contribute to the nutrient content of the compost. They contain valuable minerals and organic matter that can enrich the composting process.

  • Fresh mushrooms or spent mushrooms that are no longer edible can be added to the compost. However, if the mushrooms are cooked or seasoned, it’s best to avoid adding them, as the added oils, salts, or spices may not be suitable for composting.
  • Chop or break larger mushrooms into smaller pieces to speed up their decomposition process in the compost pile. This helps them break down more efficiently and integrate with other organic matter.
  • Mushrooms are relatively high in nitrogen, so be sure to add them along with sufficient carbon-rich materials like dry leaves, straw, or shredded paper to maintain a proper balance.
  • Mushrooms require a moist environment to decompose effectively. Regularly turning or mixing the compost helps provide the necessary oxygen and prevents the pile from becoming overly compacted.

Can You Compost Mushrooms 2

Mushroom composts have a naturally high pH, which can make the soil more alkaline. This alkalinity may not be suitable for plants that prefer acidic or neutral soil conditions. Acid-loving plants, such as azaleas, rhododendrons, and blueberries, may not thrive in alkaline soil.

Certain types of mushroom compost can contain high levels of salts. Excessive salt content in the soil can lead to salt build-up and cause damage to plant roots. Salt-sensitive plants like Azaleas, Rhododendrons, Blueberries, Cranberries, Strawberries, Blackberries, Raspberries, Citrus trees, Avocado, Olives, Grapes, Apples, Pears, and Beans may suffer from salt stress if exposed to compost with high salt levels.

Plants that Benefit from Mushroom Compost


1. Vegetables

Tomatoes, peppers, cucumbers, lettuce, and zucchini can benefit from nutrient-rich compost, which promotes healthy growth and enhances soil fertility.

Nutrient Rich Alternatives to Mushroom Compost 

1. Worm Castings

Also known as vermicompost, are produced by earthworms feeding on organic matter. They are highly nutritious and contain beneficial microorganisms. Worm castings can improve soil structure, enhance nutrient availability, and promote healthy plant growth.

2. Composted Manure

Well-rotted manure from herbivorous animals, such as cows, horses, or chickens, can be an excellent source of nutrients for plants. It enriches the soil with organic matter, nitrogen, phosphorus, and potassium, among other essential elements.

3. Kitchen Scraps

Composting your kitchen scraps, such as fruit and vegetable peels, coffee grounds, and eggshells, can create a nutrient-rich compost that can be used as a soil amendment. Ensure that the composting process is well-balanced and complete to avoid any potential issues.
