Seasoning firewood is mostly time — but the method determines whether that time is six months or two years. Stack it wrong and you'll sell wet wood and lose customers. Stack it right and you'll have inventory that moves at full price and earns repeat business.
When to cut and split
The best time to cut is late winter through early spring. Trees are dormant, sap content is low, and you're giving the wood the entire dry season — spring through fall — to season before the selling season. Wood cut in March and stacked correctly can be sale-ready by October for dense hardwoods, faster for lighter species.
Split as soon as possible after cutting. Round logs dry from the ends only. Split wood exposes the interior grain and dramatically increases drying surface area. Smaller splits dry faster. If you're trying to move inventory quickly, err toward smaller splits.
Stacking method
Get it off the ground
Ground contact keeps the bottom of the pile wet indefinitely. Use pallets, pressure-treated 4x4s, or purpose-built log racks. Six inches off the ground is sufficient. This single step makes more difference than most people expect.
Stack bark side up
Bark is the wood's natural moisture barrier. Stacking bark side up sheds rain and dew away from the exposed wood. It also helps the interior dry by preventing bark from trapping moisture against the cut face.
Cover the top only
Cover the top of the pile with a tarp or metal roofing to keep rain off. Do not wrap the sides — that traps humidity and dramatically slows drying. The sides need airflow. A well-sited woodpile in full sun with good wind exposure will outperform a covered pile in a damp corner every time.
Orient rows for airflow
Stack rows so the prevailing wind passes through them, not along them. If possible, don't stack against a building wall — walls block airflow on one side and can reflect moisture back into the pile.
Drying times by species
These are guidelines for wood cut and split in early spring and properly stacked:
- Ash — 6–12 months. One of the faster-drying hardwoods. Sometimes burnable in the same season if cut early.
- Oak — 12–24 months. Dense wood, slow to dry. Plan ahead. Sells at a premium when properly seasoned.
- Sugar maple — 12–18 months. High density, worth the wait for BTU output.
- Cherry, birch — 6–12 months. Medium density, dries relatively fast.
- Pine, cedar — 3–6 months. Fast drying, lower BTU output. Good for kindling and shoulder seasons.
How to know it's ready
The only reliable answer is a moisture meter reading below 20% on a freshly split interior face. Visual cues — checking (cracking) at the ends, bark that pulls away, lighter weight — point in the right direction but aren't definitive. Measure before you sell.
Document your readings. If a customer challenges a moisture claim, you want a record. Photos of your moisture meter against freshly split pieces from a batch, dated, takes 60 seconds and protects you in a dispute.
Common mistakes
- Selling wood cut in spring as "seasoned" in the fall of the same year — most hardwoods aren't ready that fast
- Stacking in the shade against a north-facing wall — adds months to drying time
- Piling too deep — airflow can't reach the center of a pile more than 4 feet deep
- Covering the sides — traps humidity and defeats the purpose of stacking
- Measuring end grain or bark and calling it seasoned — always measure freshly split interior
