Stack it off the ground, cover only the top and leave the sides open to the air, then give it months to dry out. That is what turns a load of fresh-cut logs into firewood that lights easily and burns clean by the time the cold sets in. Heating season is close across Canada, and anyone relying on a wood stove, a fireplace insert or a backup supply for a cottage needs wood that is actually ready to burn, not still full of sap and moisture from the tree. Wood that goes into a stove too wet does not just smoke and smoulder, it also drives up the creosote that builds inside a chimney flue, a leading cause of chimney fires, according to Natural Resources Canada’s guidance on residential wood heating. Properly seasoned wood, dried to about 20 per cent moisture content or lower, burns hotter, produces less smoke and puts more heat into the room instead of boiling off water first. Getting the woodpile stacked correctly now, while there is still enough warm, dry weather left to finish the job, is what decides whether the wood on hand in December is actually usable.
- Split the wood before stacking. Splitting exposes far more surface area to air and speeds drying considerably. Whole rounds can take years to season properly, while split pieces are ready in months, according to Natural Resources Canada’s bulletin on solid biofuels and firewood.
- Keep it off the ground. Stack firewood on a pallet, a purpose-built rack, or a couple of long rails, never directly on soil or grass. Ground contact pulls moisture back into the wood and gives insects and rot an easy way in, according to the University of New Hampshire Extension’s guidance on drying firewood.
- Pick an open, sunny spot with airflow on all sides. Wind and sun do the actual drying work. A single row exposed on both long sides seasons faster than a stack pressed against a wall or crammed into a closed shed, per UNH Extension.
- Cover only the top of the stack. Use a tarp, a purpose-built cover, or a sheet of metal or plywood over just the top, weighted or tied down, and leave the sides open. Wrapping the whole pile traps moisture inside instead of letting it escape, according to Natural Resources Canada and UNH Extension.
- Stack in a single, stable row rather than a loose pile. Crisscross the end pieces every few rows, or use a simple frame or rack, to keep the stack from toppling, and keep rows narrow enough, about a metre wide, that air reaches the centre.
- Give it time: at least six to nine months. Freshly cut, split wood needs a minimum of six to nine months of drying time to get below the 20 per cent moisture mark, according to the University of Illinois Extension’s firewood burning-safety guidance. Wood split and stacked this fall is really building the supply for next winter’s coldest weeks, so cut or buy a year ahead when possible rather than counting on wood to be ready the same season it is split.
- Check dryness before burning. Seasoned wood is noticeably lighter than green wood, shows visible cracks radiating from the cut ends, and makes a sharp clink rather than a dull thud when two pieces are knocked together, per Illinois Extension. An inexpensive moisture meter from a hardware store gives an exact reading; aim for 20 per cent or below, in line with the range set out by Canada’s Wood Heat Organization, a federally incorporated non-profit focused on responsible wood heating.
- Keep the bulk of the woodpile a safe distance from the house or cabin, especially in a wildfire-prone area. FireSmart BC recommends storing firewood at least 10 metres from any structure where wildfire risk is a factor, with the area immediately around the house, within 1.5 metres, kept completely clear of firewood and other combustibles. Where that much space is not practical, bring in only a small working supply and keep the main stack as far from the structure as the property allows.
- Rotate stock so the oldest wood burns first. Reorganize the pile so wood that has seasoned the longest gets used first, and this year’s fresh-split wood goes toward the back, or a separate stack, to keep drying through until next season.
- Keep a small supply somewhere handy, but still ventilated. Move a few days’ worth into a porch, an open-sided shed, or a vented box near the door so it is not necessary to trudge out to the main pile in a snowstorm. Avoid sealing this bring-in wood inside a closed, damp space, which can undo the drying already done.
None of this calls for anything beyond a maul or a splitter and some lumber for a simple rack, and most of the work happens once a season. Wood that is split, stacked with airflow on all sides, covered only on top and given enough time will be dry enough to burn efficiently, and safely, well before the coldest weeks of a Canadian winter arrive.
