Yesterday’s blog post about building with juniper poles prompted me to write this blog post. Much like pallets, juniper and cedar wood is an underutilized resource, probably because these trees tend to be twisted, curved and often smallish in size. For natural builders they’re a free treasure. Juniper and cedar are rot resistant, extremely common (juniper throughout most of the western US, and red cedar in the eastern half), and extremely durable (100 year fence posts are common). Here’s an account of juniper posts that are well over 200 years old and still in fine condition. Rocky Mountain Juniper, Utah Juniper and Western Juniper are most common in the western US. Many trees are very twisted and curved. You’ll have to search out straight poles for post and beam construction. It’s much easier to find straight eastern red cedar poles. Sources include farm and ranch suppliers, Craig’s List, and getting permission to cut wood on large ranches, forests and BLM land.

“Juniper is an evergreen shrub/tree with irregular form, twisted trunks and branches. Found in dry, rocky, and open habitats. The juniper is long-lived. American Indians used the bark for cordage, sandals, woven bags, thatching and matting. They also ate the berries fresh or in cakes. Junipers are also called cedars.” — Native Plants

“Eastern red cedar (Juniperus virginiana) is a slow-growing, narrow-leaved evergreen growing in a narrow pyramidal form to 45 feet. Native to North America east of the Rocky Mountains, and isolated populations in Oregon, this common tree was revered by Native Americans for its many and varied uses. The wood of red cedar is very durable, and was used for lance shafts, bows, and other items. Flutes made from red cedar wood were highly regarded by the Cheyenne. Cedar boughs were used for bedding. The Menomini wove mats of cedar bark. The mats were used for roofing temporary structures, for partitions, floor mats and wrappings, and for various purposes in the canoes.” – Cirrus Image.com

“We in Central Texas are very fortunate to have access to one of the most beautiful, durable woods for use in building – ashe juniper. Commonly called “cedar”, this often-maligned tree is a blessing for those of us in the natural building world. It can be milled into beautiful slabs for uses such as window sills or headers; or better yet, it can be used in its beautifully flowing irregular shape for arbors, garden gates, balustrades, trellises and much more. Using natural, unmilled wood, or roundwood is not only unique and beautiful, but it is a sustainable thing to do in that it uses a regional material that is generally considered a waste wood, transportation fuel and costs are minimized, and milling energy is avoided.” – Frank Meyer, Design-Build-Live (Top strawbale/earth floor building guru and musician.)

    I just read over this — the last comment takes me back a little… maybe you were talking about junipers as opposed to cedars, but I still have not figured out the difference… (they look the same to me)…

    When we were building a starter cabin in Arkansas a few years ago (before a massive Oak fell on it & totaled it) we used fresh cut, local Cedar…

    The interior walls were decorated with the planks… & then my wife fainted… long story short — the cedar not only made her faint but itt mad me drowsy — like I’d taken Benadryl or something… the folks at the ER thought my wife had been on drugs!!

    After we began to research it it seems I remember something about it letting off a cyanide gas when burned… so be careful if using this for firewood!!

      Not sure exactly what comment you’re talking about. Cedar and jumpier are closely related and have some of the same desirable qualities (insect resistance, durability, hearty growth in harsh environments…). We burned tons of this wood in our wood stove for many years and never had a problem with the smell. Million of people have cedar chests…

    Some say junipers are “weed trees”, “invasive plants”. That’s what I’ve heard. It’s true in a sense, but they do a lot of good.

    My grandfather built with fence posts made of Black Locust in the 30′s. They are still there and none of them are rotted. I’ve had to replace some of the barb wire but not the posts.

    • Owen Geiger says:

      Yeah, black locust is another super durable wood like osage orange. Ever see that wood? We used to throw the seed balls when I was a kid in Iowa. Maybe I should roll all these into another blog post.

      • Chris Fox says:

        We used them to pelt each other with them : D Visited a farm once where they had set up wind breaks and large hedge rows out of osage orange. Said they grew it to about 10 feet then cut it back and lay down the branches to the ground weaving them together to form the hedges.

  4. Rex says:

    We’ve used them in fence posts often. They just have what it takes to last a very long time. Everyone just forget the commodity driven stuff ;) and you
    can make gin out of junipers. Tell me what other tree can do that for you!

  5. Owen Geiger says:

    Another plus that I just thought of — junipers and cedars are common on desolate rural land. I’m talking about land out west that looks like BLM land. We often recommend building in remote, rural areas with few building codes, so using cedar and juniper just makes sense. Makes good firewood, too.
