Is White Cedar a Good Firewood?

White Cedar, also called Northern White Cedar or Arborvitae, is the one species on this list that actually earns a "poor" overall rating. And yeah, there's a reason for that.

At just 11.6 million BTU per cord and only 1,870 lbs dry, this is about as low as firewood goes. You'd need to burn nearly three cords of White Cedar to match what two cords of red oak would give you. Check the firewood cost comparison and you'll see why that math doesn't work out.

The only real upside for handling? It splits like butter. Practically falls apart on the chopping block. But it's a spark thrower, so never burn it in an open fireplace without a screen. The smoke level is moderate and the fragrance is pleasant, that classic cedar smell, though not quite as strong as its red cedar cousins.

Seasoning is quick at 3 to 6 months. So at least you're not waiting years for wood that doesn't produce much heat. Small victories.

Look, I'm not going to sugarcoat it. White Cedar is a kindling wood and that's about it. The coals are poor, it burns through incredibly fast, and the heat output just isn't there for anything serious. If you've got a pile of it from clearing some land, use it to get your fires started and mix in something heavier for the actual burn. Common throughout the Northeast and Midwest, so you'll see plenty of it. For a cedar that actually performs better, take a look at Eastern Redcedar, same family, a little more to offer.

How Long Does White Cedar Take to Season?

White Cedar 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 White Cedar 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.

For detailed drying timelines for all 70 species, see our firewood seasoning guide. And if you want to understand why seasoning matters so much, our green vs seasoned firewood page breaks down exactly what happens when you burn wet wood.

Can You Burn White Cedar in a Fireplace?

White Cedar 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 White Cedar 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 White Cedar 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 White Cedar’s 11.6 million BTU per cord.

Can you burn White Cedar in a fireplace?
White Cedar is not recommended for open fireplaces due to heavy sparking. Use it in a closed wood stove or fireplace insert with glass doors instead.
How many BTU does White Cedar firewood produce?
White Cedar produces 11.6 million BTU per cord when properly seasoned. That's on the lower end, best suited for kindling, quick fires, or supplemental heat.
