I have three compost bins. I thought that I'd try that instead of always burning my leaves. The piles were warm for a while but now they are stone cold. I have shredded the leaves but I have no green stuff to add to the piles. Can I add something else to get it going? I have acess to lots of coffee grounds, would that help? There are plenty of worms in there. Also, where I had to put them was near a white pine tree so a fair amount of needles are in the mix. Could this be a problem? TIA
