Question: Just cut done cutting some firewood. I have a lot of small sized wood. How big around should the wood be to split. Does a 4 to 6 inch log need split and will it be seasoned if not. Answer: Smaller pieces burn faster than larger ones. Thick pieces are good for getting an overnight burn. Smaller pieces are nice for starting up the fire, or maybe just getting a small early fall fire going. There's a time and a place for all sizes of log. Most people cut their logs to fit in their fireplace or their woodstove. A 4" or 6" log would might need to be split if it's from a really thick tree, and it might be easier to get in the woodstove. Then again, it might not, experience will help you make the right decisions. Check out : https://www.hearth.com/what/essentials.html for some more answers.
