For optimal burning, firewood should be dried, or “seasoned,” until its moisture content is less than 20 percent. Firewood with a moisture content higher than that may eventually burn, but it is devilishly hard to light and just as hard to keep burning.
Can firewood be too dry?
Yes, although it is not a common problem. Properly seasoned firewood still has a fair amount of water in it, say 15 to 20 percent of its weight. That water regulates the combustion process along with a few other factors like piece size, load configuration and combustion air supply.
What is a good moisture level for firewood?
It’s important to burn only wood with moisture content below 20%. Burning wood with higher moisture content creates more smoke, which contains harmful chemicals and particulates and forms creosote on your chimney. It also gives you less heat, because it takes energy to boil off the excess water.
How do you know if firewood is dry enough to burn?
To identify well-seasoned wood, check the ends of the logs. If they are dark in colour and cracked, they are dry. Dry seasoned wood is lighter in weight than wet wood and makes a hollow sound when hitting two pieces together. If there is any green colour visible or bark is hard to peel, the log is not yet dry.
How long should firewood dry before?
Generally you should dry or “season” firewood for six to 18 months before burning. But Mike Kuhns, a Utah State University professor and extension forester, says that time frame can be too broad to be useful. Luckily there are plenty of ways to narrow that window.
Is a standing dead tree seasoned?
Since your trees are already dead, the curing process will have already started, and the wood should be dry enough to burn in a shorter time period. The best wood is typically seasoned for two to three years but will start to deteriorate after four to five years and will not be good to burn.
Can firewood be seasoned too long?
As long as firewood is left to sit in the right conditions and free from moisture it won’t go bad for many years. Once firewood has been seasoned for the right amount of time it should be stored off the ground, under a form of cover and open to the atmosphere to ensure that it doesn’t rot.
How do you dry firewood quickly?

Can you burn freshly cut wood?
No matter which way you cut it (or split it with your trusty log splitter), fresh wood just doesn’t burn right. Fresh-cut wood has a high moisture content, which makes it hard to get burning. It also gives off more smoke.
Can you burn 25% moisture wood?
You don’t want to be burning any wood with over 25% moisture content as the wood will become progressively harder to burn. Poor combustion of wet wood will lead to more smoke being produced and less heat being generated by the fire.
How can you tell if firewood is too wet?
How To Tell If Firewood Is Wet. Firewood that is too wet to burn will be harder to light and harder to keep burning, and may produce more smoke than usual. Wet firewood can have moisture visible under the bark or feel wet to the touch, and will have a moisture content level higher than 20%.
How can you tell if firewood is seasoned?
Seasoned wood will be darker in color than green wood, and may be cracking at the ends. Seasoned wood can also lighter in weight and the bark can be peeled off more easily than unseasoned wood. A moisture meter will be able to provide an accurate reading of whether firewood is fully seasoned or not.
Should you cover firewood with a tarp?
If firewood is seasoned, dry and ready to burn, then it should have a tarp over the top of the stack to protect it from the elements. However, do not cover the sides of the stack with a tarp, or the wood may rot. Even after the wood is dry, the stack needs good air circulation to keep moisture out.
Will a fan help dry firewood?
Using a fan can help dry firewood, so long as the environment is free of humidity along with being warm and dry. As a matter of fact, if done right, a fan can speed up the seasoning process, bringing the time down to only a matter of weeks versus several months.
What happens if seasoned wood gets wet?
If your fully seasoned firewood and is stored outside without any sufficient cover or placed on moist ground, the wood will start to go bad and rot over time. It’s therefore important that any seasoned firewood is kept dry, and if the wood has been rained on it should be moved to a dry location as soon as possible.
What wood should you not burn?
Watch out for any wood covered with vines. Burning poison ivy, poison sumac, poison oak, or pretty much anything else with “poison” in the name releases the irritant oil urushiol into the smoke. Breathing it in can cause lung irritation and severe allergic respiratory problems, the Centers for Disease Control state.
How long does it take oak to dry for firewood?
When using the air-drying method, you can expect oak firewood to take about six to 24 months to fully cure. If your oak firewood is still green and has a high moisture content of about 70% to 80%, allowing it to air dry for six months to two years should result in a moisture content of 20% or lower.
Can you burn tree wood?
Technically, you can burn a tree that was cut down yesterday, but its usefulness relies greatly on whether or not the tree was already dead. Burning a recently cut live tree’s wood, referred to as “green wood,” is not the best use of the resource or safe in a home.
