I am trying to break down a large amount of wood from juniper shrubs that, even after years, seems to be resisting decay much more so than other types of wood we have present. As an experiment, I put some of it in two different holes that are about 2 feet deep and 3 feet wide (I need to fill the holes in anyway), threw on some old nitrogen fertilizer and topped with some green vines and weeds I just pulled. The piles are loosely stacked so a fair amount of air should still be getting in. The piles are near the edge of the woods and get maybe a few hours of direct sun and otherwise are in light that is filtered by the forest canopy. Other juniper clippings are still scattered in the woods where they were illegally dumped and are also resisting decay but are in bits too numerous and small to bother picking up.
Any thoughts on whether my experiment will speed things up or what to do to speed things up would be appreciated.
