How to Season and Store Firewood So It Actually Burns Well

Freshly cut wood doesn’t burn well. It hisses, smokes and struggles to hold a flame, because the fire spends its energy boiling off water instead of producing heat. Seasoning, meaning drying split wood in the open air, turns a log that fights you into one that lights quickly, burns hot and leaves far less soot behind. Good firewood is mostly a matter of planning ahead and stacking it right.

Quick answer: Split wood soon after cutting, stack it off the ground in loose rows in a sunny, breezy spot, and cover only the top. Softwoods usually dry in about 6–12 months; dense hardwoods like oak often need 1–2 years. Wood is ready when it reads under about 20% moisture on a meter tested on a fresh split face, shows cracked ends, and sounds hollow when two pieces are knocked together.

Why Seasoning Matters

Green wood can be around half water by weight. Burning it wastes heat, produces heavy smoke and leaves unburned tar that condenses in chimneys and stove pipes as creosote, a flammable buildup that can cause chimney fires. Dry wood burns hotter and cleaner. For outdoor fire pits, dry wood also means much less smoke drifting into your neighbors’ windows.

Moisture content	How it burns
40–50%+ (green)	Hard to light, hissing, heavy smoke, little heat
25–35% (partly seasoned)	Lights slowly, smoky, more creosote
About 20% or below (seasoned)	Lights easily, burns hot and clean

How Long Seasoning Takes

Wood	Typical seasoning time	Notes
Pine, spruce, fir	About 6–12 months	Light, resinous; great kindling
Poplar, aspen, basswood	About 6–12 months	Lower heat output
Birch, cherry, soft maple	About 9–18 months	Birch bark holds moisture; split well
Ash	About 6–12 months	Relatively low moisture when fresh
Hard maple, hickory, beech	About 12–24 months	High heat output
Oak	Often 18–24 months or more	Dense; worth the wait

Climate matters too: wood dries faster in warm, dry, windy regions than in cool, humid ones. If you’re buying wood, ask when it was split and stacked. “Seasoned” on a sign doesn’t guarantee it’s dry.

Step 1: Cut and Split Early

Wood dries mostly through its cut ends and split faces, so whole rounds dry very slowly.

• Cut logs to a length that fits your stove or fire pit, typically about 16 inches for many stoves.
• Split rounds soon after cutting; smaller pieces dry faster.
• Aim for pieces about 3–6 inches across.

Splitting safely: use a splitting maul rather than a felling axe, split on a sturdy chopping block, wear eye protection and boots, keep your feet apart and keep others well away from your swing. For large volumes, a rented log splitter saves time and your back. Our chainsaw buying guide covers cutting rounds safely.

Step 2: Stack It for Airflow

Do	Don’t
Stack on pallets, rails or a raised firewood rack	Stack directly on soil or grass
Use single rows with gaps between them	Pile wood into a tight heap
Choose a sunny, breezy location	Tuck the pile in a shady, still corner
Cover only the top	Wrap the whole pile in a tarp
Keep bark side up on the top layer to shed rain	Leave the top exposed to heavy rain and snow
Keep the main pile away from the house	Stack against siding (moisture and pests)

Crisscrossed end stacks, or end posts, keep rows stable. Keep a smaller supply of dry wood near the door for convenience, and restock it every few days.

Step 3: Test Whether It’s Ready

• Moisture meter: split a piece and press the pins into the fresh face, along the grain. Under about 20% is ready.
• Cracks: seasoned wood shows checks (cracks) radiating from the center of the cut ends.
• Color: ends turn gray or dull rather than bright and fresh.
• Weight: seasoned pieces feel noticeably lighter.
• Sound: knocked together, dry pieces make a sharp, hollow crack; green wood makes a dull thud.
• Bark: often loose or falling off.

Choosing Wood for the Job

Goal	Good choices
Kindling and quick starts	Pine, spruce, fir, cedar (small split pieces)
Long, steady heat	Oak, hickory, hard maple, beech
Easy, all-round burning	Ash, cherry, birch
Fire pits with guests nearby	Well-seasoned hardwood, which makes less smoke and fewer sparks

Don’t burn painted, stained or pressure-treated wood, plywood, pallets with unknown treatment or driftwood, which can release harmful fumes.

How Much Wood Do You Need?

A full cord is a stacked pile 4 feet high, 4 feet deep and 8 feet long (128 cubic feet). A “face cord” or “rick” is usually one row, 4 by 8 feet, with pieces about 16 inches long, which is about a third of a full cord. Always ask a seller to define the unit.

Use	Rough annual need
Occasional fire pit or fireplace fires	A face cord or less
Regular weekend fires in a fireplace	About half a cord to a cord
Wood stove as supplemental heat	Often 1–3 cords
Wood as primary heat in a cold climate	Several cords, depending on the house and stove

Buy or cut next year’s wood this year, so it has a full season to dry.

Common Mistakes

• Buying wood in fall to burn the same winter. It’s often still green.
• Stacking whole rounds. Split first.
• Tarping the whole pile. It traps moisture.
• Storing wood indoors long-term. It can bring insects inside; bring in only a few days’ worth.
• Burning wet wood “just this once.” It builds creosote. Have chimneys inspected and cleaned as needed.

Troubleshooting

Problem	Likely cause	Fix
Fire smokes heavily	Wet wood	Test moisture; burn only seasoned wood
Wood hisses or bubbles at the ends	Green wood	Let it dry longer
Bottom layer is moldy or rotting	Stack on the ground	Raise the pile on pallets or a rack
Pile dries slowly	Shade, tight stacking, fully covered	Move to sun, stack in loose rows, cover only the top
Insects in the house	Wood stored indoors	Bring in only what you’ll burn soon

FAQ

Can I burn wood that was cut this year?

Usually not well. Most wood needs at least six months, and dense hardwoods a year or more, after splitting.

Should firewood be covered?

Cover the top to keep rain and snow off, but leave the sides open so air can move through.

What moisture should firewood be?

About 20% or less, measured on a freshly split face.

Is kiln-dried firewood worth it?

It’s ready to burn immediately and good for occasional use or late planning. It costs more, so seasoning your own is cheaper if you have space and time.
