Is Western Redcedar a Good Firewood?
Out in the Pacific Northwest, Western Redcedar is everywhere. And I mean everywhere. If you've cleared land or had storm damage in Oregon or Washington, chances are you've got a pile of this stuff.
Now here's what surprised me. At 18.2 million BTU per cord, Western Redcedar produces significantly more heat than most softwoods and even some lower-tier hardwoods. At 2,632 lbs dry and 2,950 lbs green, it's not super heavy but it's got more substance than its Northern and Eastern cousins. Compare it against other firewood types and it holds up better than you'd expect.
Splitting is moderately difficult, not because it's super dense, but because the grain can be stringy and fibrous, especially on bigger rounds. A sharp maul works, just expect some stubborn pieces. The smoke level is moderate and the fragrance is excellent, that classic, unmistakable cedar aroma that fills the whole yard when you're bucking rounds.
Western Redcedar seasons fast, 3 to 6 months. That low green-to-dry weight ratio means there's not a ton of moisture to drive off. Split it in early spring and you're good to go by summer.
Here's the real talk, though: it sparks. A lot. Do not burn this in an open fireplace. In a closed wood stove with a screen, it's fine, but uncontained Western Redcedar fires will throw embers everywhere. The coals are poor, so it burns hot and fast rather than slow and steady. Use it for quick warmth, shoulder season burns, and kindling, or mix it with a dense hardwood. If you want to compare it to a lighter-duty cedar option, check out White Cedar.

Try it freeHow Long Does Western Redcedar Take to Season?
Western Redcedar firewood seasons in about 3–6 months — one of the fastest-drying species available. Split it in spring, stack it with good airflow, and it should be ready to burn by fall. The relatively low density that keeps its BTU output moderate also means moisture escapes quickly compared to denser hardwoods like oak or hickory.
Because Western Redcedar dries quickly, it’s an excellent choice if you need firewood on short notice. Even wood cut in late spring can be ready by October in a warm, breezy location. Just make sure to get it off the ground and cover the top only — wrapping the whole stack traps moisture and defeats the purpose.

Can You Burn Western Redcedar in a Fireplace?
Western Redcedar is not recommended for open fireplaces. It throws many sparks — more than most species — which is a genuine safety hazard when there’s no barrier between the fire and your living space. A single ember landing on carpet or furniture can start a house fire. Burn Western Redcedar exclusively in a closed wood stove or a fireplace insert with sealed glass doors, where it performs beautifully.
If you want the heat output of Western Redcedar without the fireplace concerns, a modern EPA-certified wood stove is the best option. Stoves contain sparks completely, operate at much higher efficiency than open fireplaces (72% vs 10–15%), and let you take full advantage of Western Redcedar’s 18.2 million BTU per cord.
