💧 Half of What You Bought Is Water
Not damp. Not a bit green. Freshly cut wood is close to half water by weight.
Before a log of it warms anything at all, your fire has to boil that water off — and the heat to do the boiling comes out of the fire itself. You are burning firewood to make steam, and paying for the privilege in the only currency that matters on a January night, which is heat that never reaches the room.
That is why green wood hisses. It is why it foams and bubbles at the cut ends. It is why the fire goes dark and sullen and wants poking every twenty minutes while everybody in the room keeps their sweater on.
Take the same tree, the same size log, dried down under twenty per cent, and it burns like it means it. Nothing about the wood changed. Only the water left.
🔥 The Chimney Fire You Are Building
Everything above is money and aggravation. This part is the house.
A cool, smoky fire does not burn its own smoke. Those unburned gases go up the flue, meet cold masonry and condense into creosote — a tarry, flammable glaze that thickens coat by coat all winter long. Creosote is what chimney fires are made of. A man burning green wood is building a chimney fire in his own flue, one damp log at a time, and it is quiet work. He does not find out he has been doing it until the chimney is roaring and somebody is dialling the fire department.
Two things follow from that, and neither is optional.
Burn dry wood. It is the only thing you control that meaningfully changes how fast creosote builds.
Have the chimney swept every year by somebody who does it for a living, and have it done whether you think it needs it or not. A sweep will also tell you what your burning habits are doing up there, which is information you cannot get from the hearth end. This is not a job to save money on and it is not a job to do off a ladder at seventy.
📅 How Long It Actually Takes
Longer than anybody wants it to, and the number that matters is not the calendar date it was cut. It is the date it was split and stacked, because a round log dries at a crawl.
Most species: six to twelve months, split and stacked in the open air, cut in spring for the following winter.
Oak: give it two years. It is dense, it holds water like a sponge, and it will punish a man who rushes it. The reward is that seasoned oak is about the best firewood there is.
Softwoods dry faster — often inside six months — but they burn quicker and carry more resin, so they earn their keep as kindling and shoulder-season wood rather than as the thing you bank the stove with at bedtime.
The rule that does most of the work: it has to be SPLIT. Bark is waterproof. That is its entire job, and it does it just as well after the tree is down. Leave a log in the round and it will sit in your yard for three years and still be wet in the middle. Split it and you have opened every face of it to the air.
Which is why a woodpile is a spring job for next winter, and never a winter job for this one. The wood you burn this year should have been somebody’s afternoon two summers ago.
🔍 How to Tell, Standing There in the Yard
You will be offered wood by somebody who says it is seasoned. He may even believe it. Here is how you check, with nothing but your hands.
Look at the end grain. Seasoned wood cracks as it dries, and those cracks radiate out from the centre of the cut face like spokes. Green wood is smooth.
Look at the colour. Grey, dull, weathered. Fresh-cut brightness means fresh cut.
Pick it up. Half the water is gone, so seasoned wood is startlingly light for its size once you have handled both.
Knock two pieces together. This is the best one and it costs nothing. Seasoned wood rings. Green wood thuds. Once you have heard the difference you will never need to be told again.
And look at the bark. On well-seasoned wood it is often loose, or falling off entirely.
If you buy a moisture meter — and they cost very little — use it properly. Do not press the pins into the outside of a log, because the outside dries first and will read low after any rain-free week. Split a piece open and test the fresh inside face. That is the reading that tells the truth. Under 20% is ready. Over 25% and you are boiling water.
🪵 Stacking It So It Actually Dries
You can do everything else right and undo it with a tarp. This is the part people get wrong.
Off the ground. Pallets, rails, two-by-fours, anything. Wood stacked on soil wicks moisture up out of the ground all winter and rots from the bottom row.
Top covered, sides wide open. Here is the mistake: a tarp thrown over the whole pile and tied down keeps rain off and traps every bit of evaporating moisture inside, so the pile sweats and stays wet. Cover the top third and leave the ends and sides breathing.
Sun and wind, not shade. Wind does more of the drying than sun does. A single row exposed to the prevailing wind will beat a fat pile in a sheltered corner every time.
Not stacked against the house. It holds damp against your siding, it is an invitation to carpenter ants and termites, and a large pile of fuel against a wall is a thing fire departments would rather you did not do. Keep the working week’s worth by the door and the rest of it out in the yard.
🧓 Why You Buy the Maul at Fifty
Splitting wood at fifty is exercise. At seventy-five it is a risk assessment, and the assessment is mostly about your shoulders, your balance and whether anybody would find you.
So the argument of this whole site applies to firewood more literally than to almost anything else. The tools and the infrastructure get bought and built while swinging things is still fun. A good rack put up at fifty is still standing at seventy-five and has saved you ten thousand bends at the waist. A maul bought at fifty is the same maul at seventy-five, because a forged head on a hickory handle does not wear out — you do.
And the honest part: the day comes when you stop swinging and start buying it split. That day arrives sooner for some men than others and there is no shame in it whatsoever. What matters is that the drying and the stacking and the covering still have to be right, because none of that changes when somebody else does the splitting.
A word on the kindling splitter, because it is the one people have not heard of. It is a fixed blade in a ring that you set the wood on and strike — no swinging, no aiming, nothing held in the hand you are hitting toward. For splitting kindling it removes the single most dangerous motion in the whole business, and it does it at any age.
Two more things, both free. Wear the gloves — there is a whole page on which kind for which job. And do not split alone if you have got to the stage where a fall would be a serious matter; the wood will wait for a Saturday when somebody else is in the yard.
❓ The Questions People Actually Ask
Short answers. Where the page has already covered something properly, the answer points back rather than saying it twice.
How can I tell if firewood is seasoned without a meter?
Knock two pieces together — seasoned rings, green thuds — and look for cracks radiating from the end grain. The full set of checks is in How to Tell, Standing There in the Yard.
How long does firewood take to season?
Six to twelve months for most species, split and stacked; two years for oak. The detail, and why the split date matters more than the cut date, is in How Long It Actually Takes.
Can I burn wood the same year the tree came down?
You can make it burn. That is not the same as it being fit to burn. People say “it burned fine” because wood will eventually catch if you work at it hard enough with enough kindling — but burning fine and heating the house are different claims, and the creosote is accumulating either way. A tree that came down in your yard in October is firewood for the winter after next. If you need wood this winter, buy seasoned wood from somebody and start your own pile for next time on the same afternoon.
Should I cover my woodpile with a tarp?
Cover the top only. A tarp over the whole pile makes it wetter, not drier. Rain is not the main enemy once wood is stacked properly — trapped evaporation is. Water leaving the wood has to go somewhere, and a sealed tarp turns your woodpile into a sweat lodge. Top third covered, ends and sides open to the wind.
Is a moisture meter worth buying?
Yes, and mostly because it settles arguments with firewood sellers. They cost less than a tank of fuel. The critical part is using it right: readings taken on the outside of a log are meaningless, because the outer inch dries first. Split a piece and press the pins into the fresh inner face. Under 20% is ready to burn, 20–25% is marginal, and above that you are heating water instead of your house.
🛒 Buy It at Fifty
Everything on this page comes down to one thing, and it is the same thing this whole site is about.
You cannot buy dry wood in January. Not really. What is for sale in January is wet wood at a good price, sold by men who know exactly what month it is, to people who have run out of options and firewood on the same weekend.
The man who is warm in January stacked his in April. He was not being virtuous and he was not being clever. He simply did the thing at the only time it could be done, which was long before he needed it.
That is the whole argument, and firewood happens to be the version of it you can stand next to and look at.
