Cedar vs pine for raised beds
Cedar and pine are the two most common choices for a raised bed frame in most of the United States, and the choice mostly comes down to how long you want the frame to last against how much you want to spend building it. Redwood, covered briefly at the end of this guide, behaves similarly to cedar where it is available.
Cedar: pay more, replace less often
Cedar heartwood contains natural oils that resist rot and insects without any chemical treatment. An untreated cedar frame in direct soil contact commonly lasts eight to fifteen years depending on climate and how consistently wet the site stays; a bed that drains well and dries out between rains will generally outlast one sitting in a low, damp spot. Cedar costs more per board foot than pine, often noticeably more, but it needs no additional treatment and nothing extra to buy at the point of building.
Untreated pine: cheap now, replaced sooner
Pine is usually the least expensive option at the lumber yard, and for many builders that price difference is the whole reason to consider it. The tradeoff is durability: untreated pine in direct contact with damp soil typically breaks down within three to six years, closer to three in consistently wet climates and closer to six in drier ones. For a bed you expect to rebuild or replace within a few years anyway, or for a low cost first bed to try raised bed gardening before investing more, untreated pine is a reasonable choice.
Pressure treated pine: the middle ground
Ground contact rated pressure treated pine closes much of the durability gap with cedar, often reaching fifteen years or more, while staying closer to pine's price than cedar's. Modern residential pressure treatments use copper based formulas rather than the older chromated copper arsenate treatment that was phased out of residential lumber years ago; check the tag at the yard for the specific treatment used and confirm it is rated for ground contact rather than only above ground use, since the two ratings use different chemical concentrations.
Is treated wood safe for a food garden
Current guidance generally treats modern copper based pressure treated lumber as acceptable for garden use, unlike the older arsenic based treatment. If you would rather the treated wood not touch the soil directly as an extra precaution, a landscape fabric liner along the interior walls, covered in the build variants of each plan in the Raised Bed Build Pack, adds a barrier without blocking drainage.
What to avoid regardless of species
Reused railroad ties, utility poles, or other salvaged treated timber are a different category of product from residential pressure treated lumber, often treated with creosote or older formulations not rated for garden contact, and should not be used for a bed growing food.
Making the call for your build
If budget is the main constraint and you are comfortable replacing boards in a few years, untreated pine keeps the upfront cost lowest. If you would rather build once and not think about it again for a decade or more, cedar or ground contact rated pressure treated pine are the two realistic options, with cedar costing more but needing no chemical treatment. The free configurator lets you compare the cut list and board count for the same bed size across cedar, pine, and redwood so you can price out the actual lumber cost difference for your specific dimensions before deciding.
Cedar vs Pine Quick Choice Table
Use this table to compare common raised bed lumber choices by expected life and best use.
| Wood choice | Typical life | Best use |
|---|---|---|
| Cedar | 8 to 15 years | Long-term bed |
| Untreated pine | 3 to 6 years | Lowest upfront cost |
| Pressure treated pine | 15+ years | Durable, lower cost |
| Redwood | Similar to cedar | Where available |
| Railroad ties | Avoid | Not for food beds |
Use the life range to match the lumber to your plan: short-term savings favor pine, while cedar or ground contact treated pine fits a decade-plus bed.
