Is mushroom compost good for all plants?
However, mushroom compost isn’t for every plant because it is rich in soluble salts and other nutrients. These can kill germinating seeds and harm salt-sensitive plants including rhododendrons, azaleas, camellias, and other members of the heath family (OSU).
Can compost burn your plants?
Compost can burn your plants when it is not used properly. If the gardener uses too much compost on each plant or they choose to use the compost before it is ready, it can potentially burn your plants. When compost is used well, it can help your plants grow and thrive instead.

Which is better leaf compost or mushroom compost?
Mushroom compost is higher in nitrogen, which boosts green growth of all plants, and phosphorus, which supports fruiting and flowering. The downsides of leaf mulch are that it’s low in nitrogen, so it doesn’t act as a fertilizer per se, and it takes a bit of elbow grease to collect and make.
Is mushroom compost acidic or alkaline?

Bagged compost can be preserved for up to 6 months. After a year, the volume and microbial activity will reduce considerably. Generally, compost will last for about a year if it’s stored in a cool location and moisture levels are monitored.
What is the NPK of mushroom compost?
As previously mentioned, mushroom compost typically has a 1:1:1 N-P-K ratio. The composting process metabolizes and stabilizes these nutrients so that they are converted into a slow-release form.
