I've been feeding my woodstove for 42 years. My 100+ acres is a mixture of Red and Chestnut Oak, Hickory, Ash, and Cherry. Our Elm all died out probably 35 years ago, and now Ash is fading fast due to the Emerald Borers. Funny...here in the Northeast we would never consider burning softwoods like Pine, Hemlock, or Cedar, but when I travel out west to hunt, that's all they burn out there. You use what you have, I guess.
