You cut it, split it, and stacked it. Now it sits through summer and fall and you pull from it all winter. Simple enough.
Except a lot of men spend real time processing firewood and then lose a third of it to rot, pests, or moisture because they did not pay attention to how it was stored. Wood piled wrong does not season. Wood stored wet does not burn well. Wood stacked directly on the ground in the back corner of the yard is doing something, but not what you want it to do.
Here is how to store firewood so that the work you put in at the splitting block actually pays off in January.
Location: Where You Put the Pile Matters
Start with where you put the pile and get this right before you stack a single piece.
Sun and wind are your friends. Firewood seasons because moisture leaves the wood, and moisture leaves faster when there is sun warming the stack and wind moving air across it. A pile in a shaded corner against the north side of a building takes significantly longer to season than the same pile in an open spot with afternoon sun and airflow. If you have a choice, put the pile where it gets the most sun and wind exposure.
Keep distance from the house. Most recommendations land at three to five feet minimum between the woodpile and the structure. The reason is twofold. First, a woodpile sitting against the house creates a path for moisture to wick toward the foundation and siding. Second, firewood is excellent habitat for insects and rodents. Termites, ants, and mice will nest in a woodpile and from there they will work their way into the structure. Keep the pile away from the house.
Avoid low spots and drainage areas. A pile sitting in a spot where water pools after rain is a pile sitting in moisture. The bottom rows will be wet regardless of how well the wood was split and dried. Pick a spot with good drainage or build up a raised base.
Stay away from dense tree cover. Trees block wind, drop leaves into the pile, and drip condensation after rain. An open spot is better than one tucked under a canopy.
Getting the Wood Off the Ground
This is not optional. Firewood stacked directly on the ground absorbs moisture from the soil and decays from the bottom up. The bottom row of a ground-contact pile is also perfect habitat for insects, rodents, and fungus. You paid for that wood and you want to burn it, not watch it rot.
The elevation does not need to be dramatic. Three to four inches is enough to break ground contact and create airflow underneath. What you use to achieve it is a practical question.
Old pallets are the most common solution and they work well. They are often free, they are the right width for a standard firewood stack, and the slatted construction allows air to move under the pile. Check that the pallet is in decent condition before loading wood on it.
Parallel treated lumber laid on the ground does the same job. Two boards laid perpendicular to the stack direction, spaced to support the bottom row evenly, cost almost nothing and last for years.
Concrete blocks give a more permanent solution for a woodshed or fixed storage area. A few blocks under a simple frame gets the wood up and keeps it there permanently.
Whatever you use, make sure the base is level. A pile on an uneven base shifts and eventually falls, which means restacking, which is the worst possible use of a Saturday in November.
How to Stack It
The goal of stacking is to create a stable structure with airflow through the wood. A pile of wood thrown loosely into a corner has neither of those things.
Bark side up on the individual pieces. Stack each piece with the bark facing upward when possible. Bark is the natural water-shedding layer of the wood. When bark faces up, rain rolls off rather than absorbing into the cut face of the wood. This is a small individual thing that adds up across a full pile.
Cut ends facing out. The cut end grain of split wood is where moisture exits fastest. Stacking with the end grain facing out toward the prevailing wind allows the wood to continue losing moisture through the season. Do not bury the cut ends in the center of a pile.
Stack in rows, not heaps. A row of wood with the pieces laid parallel to each other in the same direction is stable, allows air to move through the column, and can be covered effectively. A heap of wood thrown together is none of those things.
Keep the rows to roughly four feet high. Higher than four feet and the stack becomes unstable. A woodpile that falls over is a dangerous mess, particularly if it falls toward a building or onto a child or a dog. Four feet is a practical limit for a freestanding stack without end supports.
Use the crisscross method at the ends. If your stack does not have a wall or post to lean against at each end, the ends will want to fall outward. The crisscross method builds stable columns at each end by alternating the direction of the top layer between courses. Think of it like a log cabin corner. The alternating layers lock against each other and keep the ends standing without any external support.
Covering: A Roof, Not a Blanket
This is where most people go wrong.
You do not want to wrap a woodpile in a tarp that goes all the way to the ground on every side. That is a tent, not a cover. A tarp that seals all four sides traps moisture inside the pile, prevents the airflow that allows the wood to continue drying, and creates a warm humid environment that is ideal for mold and rot. You will pull that tarp off in the fall and find soft gray wood that burns like a wet newspaper.
What you want is a cover over the top of the pile with the sides open. Think of it as a simple roof, not an enclosure. The job of the cover is to keep rain and snow from falling directly on the top of the pile. The sides stay open so air can move through.
A tarp works if it is secured so it covers only the top foot or so of the pile and does not drape all the way down. Bungee cords or rope tied through the tarp grommets and anchored to the pile or to stakes in the ground keeps it from blowing off. Make sure rain sheds away from the pile rather than pooling on the tarp and draining inward.
A simple lean-to roof over the pile is the more permanent solution. Two posts, a crossbar, and a piece of metal roofing or corrugated plastic provides weather protection indefinitely with no tarp management required. If you are putting up the same quantity of wood every year, this is worth building once.
An enclosed woodshed with open sides or ventilated walls is the best long-term storage solution for a serious wood heat operation. It keeps the wood dry through even difficult winters, the open sides allow airflow, and you can organize the pile properly and access it easily. Building a simple woodshed is a half-day project with basic materials.
How Long Before It Is Ready to Burn
Split hardwood stored correctly with good airflow and sun exposure needs at least six months to season to below 20 percent moisture content, which is the standard recommendation from the Connecticut Agricultural Experiment Station and consistent with most university extension guidance. This is the minimum for most hardwoods under good storage conditions.
Denser hardwoods like white oak and hickory do better with a full year, and some axe men argue for two years on white oak before it burns the way it should. Ash is the fastest of the quality hardwoods, often ready in six months under good conditions. Birch is similar. Maple and red oak want a year.
The moisture content is the number that actually matters, not the time. A cheap pin-type moisture meter poked into the end grain of a split piece tells you whether the wood is ready. Below 20 percent is the target. Below 15 is ideal and what you get from wood that has been stored well for a proper season.
Wood that was stored poorly, even if it sat for a full year, may still be above 20 percent. The time means nothing if the storage conditions were wrong.
What Happens When You Store It Wrong
The consequences of bad firewood storage show up in the stove, not in the pile. You do not always know you have a problem until you try to burn the wood.
Wet wood produces a smoky, smoldering fire. It is hard to start, hard to sustain, and produces significantly more creosote than the same species properly dried. A season of burning wet wood will coat your flue in ways that a season of burning dry wood will not. We covered the full creosote picture in the creosote guide.
Rotted wood at the bottom of a poorly stored pile is simply wasted firewood. It may be a full cord you put up and lost before you ever burned it. At current firewood prices and labor costs, that is a real loss.
Pest problems from a pile stored too close to the house or directly on the ground have a way of expanding beyond the woodpile. A wood-boring insect that establishes itself in a wet pile against the siding is a problem that outlasts the woodpile.
None of these outcomes are inevitable. They are all the result of storage decisions that are easy to get right.
FAQ: How to Store Firewood
How far off the ground should firewood be stored? Three to four inches is enough to break ground contact and allow air movement under the pile. Pallets, parallel treated lumber laid perpendicular to the stack, or concrete blocks all achieve this. The goal is preventing the bottom row from absorbing moisture from the soil and creating habitat for insects and rodents.
Should I cover firewood with a tarp? Cover the top of the pile but leave the sides open. A tarp that drapes to the ground on all sides traps moisture and prevents the airflow the wood needs to continue drying. Think of it as a roof over the pile rather than a tent around it. The cover keeps rain and snow off the top while the open sides allow air to move through.
How far from the house should I store firewood? At least three to five feet from any structure. Firewood stored against the house creates a moisture pathway toward the foundation and siding, and it is excellent habitat for insects and rodents that can work their way from the pile into the structure.
How do I know when firewood is ready to burn? A moisture meter poked into the end grain of a split piece is the most reliable method. Below 20 percent moisture content is ready to burn. Below 15 percent is ideal. Visual and physical cues include pronounced end grain checking and cracking, lighter weight than you would expect for the species, and a higher sharper sound when two pieces are knocked together compared to the dull thud of green wood.
Does firewood need to be stacked bark side up? Yes when possible. Bark is the natural water-shedding layer of the wood. Stacking with bark up allows rain to run off the natural surface rather than soaking into the cut face of the wood. This is a small advantage on each individual piece that adds up across a large pile over a long season.
How tall should a firewood stack be? A freestanding stack without wall or post support should stay at or under four feet to maintain stability. A taller stack without end supports will shift and eventually fall. If you are stacking against a wall or between posts, you can go higher, but four feet is the practical limit for a standalone stack.
The Pile You Build in Spring Is What Heats You in February
All the work at the splitting block only pays off if the wood arrives at the stove in the condition you put it up in. That means getting it off the ground, stacking it with airflow, covering the top without sealing the sides, and giving it enough time and sun exposure to actually dry.
Get those things right and the firewood you put up this spring will be ready when you need it most.
