Has anyone tried composting pistachio shells? Hubby says that they would take to long to decompose. Any thoughts?
Sure you can compost them. If you require urgent compost for some reason then hold off on them, but otherwise, no problem. They make a good mulch too.
I put some in my compost last Christmas--and they are still very much intact. So I do think they will take awhile to compost, but that's okay!
We occassionaly get Pistachios and the shells always go into the compost. Just how long they may take I am not sure but I do know that when I empty the bin, about a year after, I find none of those shells.
I throw anything like that in the bin. If I am harvesting finished compost and they have not broken down, I just toss them back in.
