Key takeaways
- Seasoned firewood means wood dried to about 20 percent moisture content or less. Fresh-cut wood can run 50 percent or higher.
- Split it first. Whole rounds dry very slowly because bark blocks moisture from leaving.
- Stack single rows off the ground, ends facing the prevailing wind, with sun on the pile if you can get it.
- Cover the top only. A tarp wrapped down the sides traps moisture and grows mold.
- Most hardwood needs six to twelve months. Oak needs closer to two years. Ash and cherry are the fast ones.

Seasoning firewood comes down to four things: split it, stack it off the ground in single rows, leave the sides open to wind, and cover only the top. Do that and most hardwood will be ready to burn in six to twelve months. Oak is the stubborn exception and wants closer to two years.
The target is roughly 20 percent moisture content, measured on a fresh split face. Anything wetter and you are boiling water in your firebox instead of making heat.
What does seasoned firewood mean?
Seasoned firewood is wood that has dried to about 20 percent moisture content or less, so it lights easily and burns hot. A tree you drop today can be half water by weight. That water has to leave before the wood gives you real heat.
The reason it matters is simple physics. Every pound of water in your firewood steals heat from the fire to turn into steam, and that steam carries unburned smoke up a cooler flue. Cool flue plus heavy smoke equals creosote, and creosote is what burns chimneys down.
Wet wood also hisses, sizzles at the end grain, and blackens your stove glass within an hour. If your glass fogs up every single burn, the wood is usually the culprit before the stove is.
How long does firewood take to season?
Plan on six to twelve months for most split hardwood stacked properly, and eighteen to twenty-four months for oak. Softer woods like poplar and pine can be ready in three to six months. Those numbers assume the wood is split, stacked in a single row, and getting air.
A round left whole in a heap can sit two years and still be wet in the middle. Bark is the tree’s raincoat and it works just as well after the tree is down. Splitting opens the end grain and the face, which is where the moisture escapes.
If you want the fuller breakdown by species and stacking method, I went deeper on that in the post on how long firewood takes to dry.
Is it too late to season firewood for this winter?
If you are cutting green wood in September, no, it will not be ready for December. Wood split now has maybe two months of decent drying weather left before the humidity and cold slow everything to a crawl. It will be much better wood for next winter.
What you can do this fall is triage. Split anything you already have down smaller, get it out of the pile and into a single row today, and buy or borrow enough seasoned wood to bridge the gap. Standing dead ash and dead limb wood are your best bets for something burnable this year.
Then work out how much you need so you are not scrambling in January. My rough math on that is in how much firewood you need for a winter, and it is worth doing before the first hard freeze.
How should you split and stack wood so it dries?
Split it to the size you will burn, then stack single rows with the cut ends exposed and a few inches of air between rows. Wood loses moisture mostly through the end grain, ten to fifteen times faster than through the sides. That is why splitting and end-exposure do more than anything else.
Get the bottom row off the dirt. Pallets, treated 4x4s, pipe, anything that keeps wood out of ground contact will stop the bottom layer from wicking moisture back up and rotting. A row sitting directly on soil will punk out from the bottom within a year.
Point the row so the open faces catch the prevailing wind, which in most WV hollows means running the stack roughly along the ridge line and not tucked behind a building. Sun helps, wind helps more. A stack in deep shade against a north wall is the slowest place on your property.

4FT Firewood Rack Holder for Fireplace, Adjustable Log Stand for Storage
A simple adjustable log stand solves the ground-contact problem for smaller stacks near the house. It keeps a row up off the wet, and the adjustable width lets you size it to whatever wall or porch corner you have. Good for the ready-to-burn wood you keep close, not for the whole year’s supply.

HKaikzo Workbench Bracket Kit
If you would rather build racks from 2x4s, bracket kits like this are the cheap way to do it. You cut lumber to whatever length fits your yard, slot in the brackets, and you have a rack that holds a single row upright without leaning on a wall. Making two shorter racks instead of one long one gives you better airflow.

Does firewood need to be covered to season?
Cover the top, leave the sides open. Rain landing on the top of a stack soaks in and slows drying, but a tarp wrapped all the way down traps ground moisture and turns the pile into a mushroom farm. Think roof, not wrapper.
A foot of overhang on each side is plenty. Old metal roofing works well and does not flap. If you use a tarp, weight it or strap it, because a loose tarp in a mountain wind will be in the next county by Thanksgiving.
Wood that gets rained on will dry back out in a few sunny days if the stack has air. Wood sealed under plastic will not.
HIRALIY Heavy Duty Firewood Tarp
A narrow, heavy-gauge firewood tarp is sized to cap a single row without draping down the sides, which is exactly what you want. The 3×8 footprint covers a short rack, and heavier fabric holds up to winter wind better than a thin utility tarp. Grommet it down at the corners and forget about it.

Does firewood season during the winter?
Yes, but slowly. Cold air holds less moisture, so on a dry, windy 25-degree day wood does lose water. What it does not do is anything close to what a hot July week accomplishes.
Winter drying is also inconsistent here. A January thaw with fog and drizzle can put moisture back into the surface of a stack. Then a clear cold snap pulls it out again.
The practical takeaway is that winter is not a seasoning season, it is a holding season. Wood you split in March and left standing all summer is the wood that carries you through February.
How can you tell if firewood is seasoned?
Split a piece and press a pin-type moisture meter into the fresh face, across the grain, in the middle of the split. Under 20 percent is good, 15 to 18 percent is better. Reading the outside of an already-split piece will lie to you low.
Without a meter, use your hands and ears. Seasoned wood feels light for its size, shows radial cracks in the end grain, has bark that comes loose easily, and makes a sharp clack when you knock two pieces together. Green wood thuds.
Weight is the most honest test of all. A seasoned split of red oak can weigh about half what the same piece weighed the day it came off the saw. If you are hauling armloads with heat-resistant stove gloves on, you will feel the difference in one season’s stacking.
Which West Virginia woods dry fastest?
Ash is the fastest good hardwood we have, often burnable in six months or less because it starts out lower in moisture than most species. Black cherry, red maple, and hickory follow behind it. Oak and elm are the slow ones.
Locust deserves a mention because it is everywhere along fence lines here and it burns long and hot. It is also dense enough that it wants a full year and a half, and it is unpleasant to split, so plan ahead with it.
Poplar and pine dry fast but burn fast too, which makes them fine shoulder-season wood for October and April. Save the oak and locust for the January nights when the wind comes down off the ridge. Keeping the saw cutting clean matters more than species, and a dull chain makes a two-hour job into an all-day one, which is why I wrote up chains that hold an edge for firewood cutting.
What slows seasoning down the most?
Stacking too tight is the most common one. Wood packed in double and triple rows with no gap has no path for air, so the inside of the stack stays damp while the outside dries. Leave finger width between splits and a few inches between rows.
The second is stacking in the wrong place. Under a deck, against the north side of the house, or in the woods behind the shed are all shady, still-air locations. Move the pile into the open even if it means a longer walk with the wheelbarrow.
The third is stacking against the house at all. Firewood piled on a foundation wall invites carpenter ants, mice, and yellow jackets, and I have written about dealing with ground nests more than once for a reason. Keep the bulk stack twenty feet out and only carry a few days’ worth to the porch.

Frequently asked questions
Does firewood need to be covered to season?
Only the top needs covering. Rain soaking into the top of a stack slows drying, but a tarp wrapped down the sides traps moisture and encourages mold and rot. Use a roof-style cover with the sides left fully open to wind.
Can you season firewood in one summer?
Yes for ash, cherry, maple, poplar, and pine if you split it small in early spring and stack it in a sunny, windy spot. Oak, elm, and locust will not get there in a single season. Split those a full year and a half ahead.
Should firewood be stacked bark up or bark down?
Bark up on the top row helps shed rain if you have no cover, and bark down elsewhere lets moisture drain out the split face. The difference is small compared to airflow and sun exposure. Do not lose sleep over it.
What moisture reading should firewood have before burning?
Aim for 20 percent or less, measured on a freshly split face with a pin meter. Fifteen to eighteen percent burns cleanest in a modern stove. Above 25 percent you will get poor heat, black glass, and creosote buildup in the flue.
The honest version of firewood seasoning is that it rewards people who work a year ahead. Split what you cut, get it off the ground in a single row somewhere sunny, put a lid on it, and leave it alone. That is most of the job.
If you are starting from nothing this September, buy seasoned wood for this winter and spend the fall building next year’s supply. Come next October you will have a stack that lights with one match and a stove glass you can see through, along with a chimney that needs far less frequent sweeping.
