Moss in the compost?

Asked June 1, 2020, 12:39 AM EDT

Can I put moss in the compost ? Will the heat kill it or make it spread through the compost pile?

I do put chunks of moss into the compost pile when I have them, but they make up very little of the volume of the compost pile - certainly less than 5%. I do not see evidence of its spreading throughout the compost. Typically moss is very low in nitrogen content and should be considered a carbon source.

Do you have great masses of moss to compost? If so, you will definitely want to add nitrogen - manure, alfalfa pellets, urine, or fertilizer, to make the compost heat up. Afterwards, I would be cautious about spreading the compost - maybe do a test patch to see whether moss spores have survived the heating process.
