Mushroom compost, also known as mushroom manure, is a type of slow-release organic plant fertiliser. It is made from a variety of organic materials, including hay, straw, corn cobs, hulls, and poultry or horse manure. Mushroom compost is created during the mushroom farming process and is removed after the mushrooms are harvested. It is often sold cheaply in bulk and can be used as a soil conditioner or mulch. However, it should be used with caution due to its high soluble salt content, which can harm seedlings and salt-sensitive plants. Mushroom compost has a pH level ranging from 6.5 to 7, making it suitable for most garden plants and a wide range of ornamental plants.

What You'll Learn
Mushroom compost is a by-product of mushroom farming
Mushroom compost is often used as a soil amendment or fertiliser in gardens, lawns, and container plants. It is rich in nutrients like nitrogen, phosphorus, and potassium, which are essential for plant growth. It also has a high organic matter content, making it useful for improving soil structure and fertility. The compost has a pH level between 6.5 and 7, making it suitable for a wide range of ornamental plants and vegetables.
However, mushroom compost should be used with caution due to its high soluble salt content and alkalinity. These salts can kill germinating seeds, harm young seedlings, and damage salt-sensitive plants like azaleas, rhododendrons, and camellias. To avoid these issues, it is recommended to mix one part mushroom compost with three parts garden soil when using it for outdoor plants in containers. Additionally, it is important to cure fresh mushroom compost before adding it to the soil to allow excess salts to be leached out by rain or snowfall.
The benefits of mushroom compost include its ability to enrich the soil, supply nutrients for plant growth, and increase the water-holding capacity of the soil, reducing the need for frequent watering. It is also reasonably inexpensive and can be bought in bulk from local mushroom farms or suppliers. However, it is important to ensure that the compost is sourced carefully, as it may contain chemicals used to treat the straw or sterilise the compost.

It is used as a soil amendment for lawns, gardens and container plants
Mushroom compost is a type of slow-release organic plant fertiliser. It is made by mushroom growers using organic materials such as hay, straw, corn cobs and hulls, and poultry or horse manure. It is added to soil to improve its fertility, structure and water-holding capacity. It can be used as a soil amendment for lawns, gardens and container plants.
Mushroom compost is a useful and inexpensive soil conditioner that enriches the soil and supplies nutrients for the healthy growth of plants. It increases the water-holding capacity of the soil, which decreases the need for watering. It is suitable for most garden plants and supports various types of plant growth, from fruits and vegetables to herbs and flowers.
However, mushroom compost should be used with caution due to its high soluble salt levels and alkalinity. These salt levels can kill germinating seeds, harm young seedlings, and cause damage to salt-sensitive plants, like azaleas and rhododendrons. It is not suitable for use on its own as a potting compost, or for growing seeds or cuttings. To temper the alkaline levels of mushroom compost, consider using aglime.
To get the greatest results when organic gardening with mushroom compost, thoroughly mix it in with the garden soil prior to planting. If spreading it on vegetable beds, leave for a week after application before sowing seeds.

It is a slow-release, organic plant fertiliser
Mushroom compost is a type of slow-release, organic plant fertiliser. It is made by mushroom growers using organic materials such as hay, straw, corn cobs and hulls, and poultry or horse manure. The process of making mushroom compost typically takes around three to four weeks. During this time, mushroom growers closely monitor the compost to maintain adequate temperatures.
The compost is created as a byproduct of mushroom farming. Once the mushrooms are harvested, the growth medium is removed and sold as fertiliser. This leftover compost is known as "spent" mushroom compost. It is generally available for purchase in large bags, bulk bags, or loose loads.
Mushroom compost is an excellent soil conditioner, enriching the soil and supplying the nutrients necessary for the healthy growth of plants. It increases the water-holding capacity of the soil, reducing the need for frequent watering. The three main plant nutrients found in the soil are nitrogen, phosphorus, and potassium, while magnesium, calcium, and sulphur are also important.
However, it is important to use mushroom compost with caution due to its high soluble salt levels and alkalinity. These salt levels can be detrimental to germinating seeds, young seedlings, and salt-sensitive plants such as azaleas, rhododendrons, and camellias. To counteract the high alkalinity, the compost can be used in moderation and alternated with well-rotted manure or garden compost, which have more neutral pH levels.

It contains a wide range of organic materials
Mushroom manure is an organic fertilizer produced from a mixture of substances that have been used to cultivate mushrooms. It is a rich, dark, and earthy material that provides an excellent source of nutrients for plants. The unique feature of mushroom manure is that it contains a diverse range of organic materials, which contribute to its fertility and benefits for gardening and agriculture.
The base ingredient of mushroom manure is usually a carbon-rich substance such as straw, hay, sawdust, or peat moss. These materials provide the mushrooms with a suitable growing medium and contribute to the overall organic matter in the manure. Straw, in particular, is commonly used because it is inexpensive, readily available, and provides an ideal structure for mycelium growth. Hay, another common choice, offers similar benefits and also contains additional nutrients that can benefit plant growth.
Additionally, mushroom manure incorporates nitrogen-rich components such as chicken manure, horse manure, or corncob bedding. These substances are added to provide a source of nitrogen, which is essential for healthy plant growth. They help promote the development of robust and vigorous plants, ensuring they have the necessary nutrients to thrive.
The process of creating mushroom manure also often involves the addition of gypsum, limestone, or superphosphate. These materials are included to adjust and balance the pH levels, ensuring that the mixture provides an optimal environment for mushroom growth. Furthermore, they can contribute additional nutrients, such as calcium and phosphorus, which are beneficial for plant health and development.
The diverse range of organic materials in mushroom manure makes it a valuable fertilizer for gardens and farms. It provides a slow-release source of nutrients, improving soil structure and promoting healthy plant growth. By incorporating mushroom manure into their gardening practices, individuals can enhance the fertility and productivity of their soil while also contributing to sustainable and eco-friendly practices.

It is alkaline in nature and has a pH of 6.5-7
Mushroom compost is a type of organic plant fertiliser. It is made from a variety of organic materials, including hay, straw, corn cobs, hulls, and poultry or horse manure. The addition of chalk makes mushroom compost a good source of calcium, which is beneficial for plants like tomatoes that are susceptible to blossom-end rot.
However, calcium increases the soil's pH level, which can be detrimental to plants that require acidic soil, such as blueberries. Mushroom compost is alkaline in nature, with a pH of 6.5-7, making it suitable for a wide range of ornamental plants and vegetables. Brassicas, for example, benefit from the higher pH, which helps protect them against club root.
The alkalinity of mushroom compost should be considered when applying it to gardens. It is not recommended for neutral, alkaline, or chalky soils, as the additional chalk will further increase the soil's alkalinity. This can lead to a buildup of chalk particles, making other nutrients in the soil less available and negatively impacting plant growth.
To manage the alkaline levels, gardeners can use aglime or alternate mushroom compost with well-rotted manure or garden compost, which are only slightly alkaline or neutral.
