After retiring four years ago I have slowly got ahead of my firewood needs and I’m now burning wood that has dried for three years. I am in Virginia, not in the great White North, so I only burn about 2 1/2 cords a year. Have been burning mostly ash, elm and maple, trees my farm neighbors gave me, with the occasional white oak, walnut, cherry, cedar, pine, sweet gum, tulip, and Black locust. But the last two winters have harvested almost exclusively oak, probably 80% Northern Red Oak and 20% white oak, blown down around here when the remnants of hurricane Michael came through in October 18. Even though I am four years ahead I am continuing to bring in the oak, most of it fairly green because it was live when blown over, not standing dead. So I am on track to be burning oak that has aged four, five, or six years.
Because the open field parts of my property are not really the place we want to store our firewood, we store it in the edge of the woods along a powerline easement. It is stacked on rails of PT lumber, with roofing or scrap plywood nailed to the top. Not optimal, but since I can let it sit there for three years, it works. No punk, mushrooms or rot. By the time I am burning it is rare for me to split a piece and have the moisture be 20% or greater. 14 to 16% is the norm.
