The Goal: Airflow In, Water Out
Firewood stays dry through two things working together: staying off wet ground, and getting enough airflow to carry moisture away as it dries. Get either one wrong and wood can sit for two years and still not season properly.
Get It Off the Ground
Never stack firewood directly on dirt or grass. Ground contact pulls moisture up into the bottom layer of wood through capillary action, and it invites rot and insects into logs that would otherwise dry out fine. Use a base of pallets, 2x4s laid a few inches apart, or a purpose-built firewood rack. Raising the stack even 4 to 6 inches off the ground makes a real difference.
Pick the Right Spot
Look for a spot that gets:
- Direct sun for at least part of the day — sun-warmed wood dries faster than shaded wood
- Wind exposure — a stack that gets crosswind dries noticeably faster than one tucked in a still, sheltered corner
- Distance from the house — keep firewood stacks at least 20 to 30 feet from your home's foundation. Woodpiles are a common entry point for termites and carpenter ants, and you don't want that colony's next stop to be your house framing.
Cover the Top, Not the Sides
This is the single most common stacking mistake. Wrapping a tarp fully around a woodpile — sides and all — traps humidity inside the stack and blocks the airflow that dries the wood. Rain hitting an uncovered top is a bigger problem than wind hitting exposed sides.
Instead, cover only the top of the stack, letting a foot or so hang over each side like a roof overhang, and leave the sides open to air. A rigid cover — a piece of metal roofing, plywood, or a solid tarp weighted at the corners — works better than a loose tarp that flaps and lets rain blow in sideways.
Stack in Rows, Bark Side Up
Stack split wood with the bark facing up on the top row, which sheds rain better than bark-down. Keep rows single-width where possible — one log deep — rather than a wide, deep pile. A single-log-deep row lets air move through both faces of every piece; a wide pile traps damp air in the center where it can't escape.
Leave a few inches of gap between separate rows if you're stacking more than one, so air can circulate between them too.
How Long Before It's Ready
Properly stacked — off the ground, covered on top, exposed to sun and wind — most split hardwood seasons to burnable moisture (20 percent or below) in 6 to 12 months. Dense woods like oak can take 12 to 24 months. Softwoods often season in 6 months or less. Split wood always dries faster than wood left in rounds, since splitting exposes far more surface area to the air.
Rotate Your Stock
Stack new wood behind or beside older wood, not on top of it, so you can always burn the oldest, driest wood first. A "first in, first out" system keeps your stack cycling instead of leaving buried wood to over-season or, worse, start absorbing moisture again from ground contact over multiple years.
Signs Your Storage Setup Isn't Working
- Wood feels heavier than it should for how long it's been stacked
- Bark is slipping off with visible mold or a sour smell underneath
- The bottom layer is darker, softer, or spongy compared to the top
- Splitting a log reveals a wet, cool interior instead of dry, lighter-colored wood
Any of these means airflow or ground contact needs fixing before the next load goes on the pile.
