I have some mulberry that was cut down in spring this year, some walnut that was cut last fall, or so I was told. This was free scrounged wood cut into rounds 16"-24" long. Four cords altogether. I was planning this to be next years wood, I have cords of other scrounged woods I am burning this year. I noticed the mulberry turned silvery in color, very seasoned looking. The walnut is a deep brown color. I picked up a cheap Harbor Freight moisture meter and cut a split of mulberry across the middle with my 12" miter saw. The meter read 13%. I cut another one, 22%. I tested a split of walnut , 19%. These splits were at the top of the pile. The 13% was smaller than the 22%.. I threw 'em all on the coals, burning nicely. The 19% walnut was a 5 inch split. So, how far down in the stack should I expect to get these readings for usable wood? The mulberry burned well, without a lot of the popping I read it is prone to. It popped a bit but not much, my seasoned cedar pops much more. When I hear it takes two years or more to season firewood, it that referring to stacks of splits, or stacks of rounds?
