Douglas fir Firewood

Douglas fir is the standard heating wood across much of the Pacific Northwest, where hardwoods are scarce. It is the densest of the common western softwoods and gives heat closer to soft hardwoods than to pine.

Splitting Douglas fir

Straight Douglas fir splits easily, which makes it pleasant to process by hand or with a small splitter.

Seasoning Douglas fir

Douglas fir dries quickly, usually in 6 to 9 months after splitting and stacking, though the wet Northwest climate makes covered storage important.

Burning Douglas fir

Dry Douglas fir burns hot and fairly fast, lights easily and has a pleasant resinous smell. It throws some sparks, so use a screen with an open fireplace.

Gear for Douglas fir

In a wet climate, a firewood shed or a rack with a good top cover makes more difference than species. Keep the sides open for airflow.
