Is mushroom compost any good?

Mushroom compost is a blend of nitrogen and carbon rich materials that are added to the soil to encourage fungal growth. This is done in order to create more food for soil microorganisms and plants, which will help increase plant growth and health. Mushroom compost can be purchased at most garden centres and nurseries, however, it is more cost effective to make your own.

How do you make mushroom compost?

 Mushroom compost is different to other composts. It contains plenty of carbon (in the form of decaying plant material), which is why it’s good for growing mushrooms. However, it also contains small amounts of nitrogen, which is needed for the mushrooms to grow.

The best way to make compost is to mix it in a bucket. You don’t want to do this in a plastic bucket, as the plastic may leach into the compost. Instead, use a metal or wooden bucket that you can wash out and reuse. Start by mixing one part of dry compost with three parts of water. When you’re making mushroom compost, add one part of wood chips or sawdust to two parts of the dry compost. Mix everything together with a spade or fork. The wood chips or sawdust will help to give your compost structure, so you don’t want to add too much. Too much structure will prevent the compost from drying out. After adding the wood chips or sawdust, stir it all together with your hands. When mixing, keep the material moving, so that the compost is mixed evenly. The more you mix, the better your compost will be. Make sure you mix in as much air as possible. How should I store it? Ideally, you should store your compost in a shed or other dry location, where it will stay dry and warm. A shed will also help to keep the compost safe from mice and rats. It should also be kept well ventilated.

How do you apply it as fertilizer?

If you plan to use it as a fertilizer for your soil, then you should not add any wood chips. A: Mushroom compost will contain some nutrients (especially nitrogen) and a lot of organic material. It may also contain some weed seeds, so you'll want to remove them before adding the compost to the soil. Wood chips are not an effective source of nitrogen, and they can harbor weed seeds. Instead of adding wood chips, you might consider adding a nitrogen-rich manure (such as rabbit, chicken, horse, or fish manure). You'll also want to add a small amount of sand to improve drainage.

More Information

Even though you can apply mushroom composts any period of the year, the most appropriate period to do so is during spring or fall.
