Make sure the flue in your fireplace is completely open to allow good air flow. The better the air flow, the hotter the fire burns, and the less the unseasoned wood smokes while burning.
Cut the unseasoned wood into small pieces, with no more than a 3-inch diameter. Wood cut to this size ignites more quickly and burns despite its high moisture content.
Burn only a few unseasoned pieces at a time for best results. Do not attempt to burn more than five of these small pieces at a time. Including too many pieces at once prevents the fire from burning as hot, increasing the likelihood that the wood will smoke and smolder.
Add fire starters, dry wood or other kindling to the fireplace when building the fire, which helps the unseasoned wood ignite and keeps the fire burning hotter.
