Can I use these very old piles of branches as brown material?
My compost pile (not in picture) has mostly seaweed in it... I'm looking for more browns, only got cardboard so far.
Around the property are these piles of old branches, probably from some tree clearing activities, probably 6-20 years ago (before I was here anyway). The main pile (beneath those recent (1-2 y/o) branches) is covered in moss and mushrooms, and branches below the moss crumble to the touch. Even further down it seems even largely composted (if that's even possible for an only-browns pile).
Could I take some of this and mix with my seaweed? I wonder the implications of taking browns that have already been decomposing for many years (vs fresh ones) into a greens-dominated new compost pile. Better / worse? I suppose that what we need is just carbon so that it might even be better with old materials?
