best way to season firewood?
Some folks stack it in orderly rows, about 4'wide, and as long as it needs to be. Others just heap it up in a big pile. I don't really think it makes a difference. Just depends on the space you have for it.
Either way, put it on pallets to keep it off the ground. With a little hunting around you can find 8'x4' pallets, and these are great for firewood.
You can cover the top of the pile with a tarp (not the sides), but unless you're in a really wet climate, I'd just leave it exposed.
