See the pick →The cedar-versus-metal question comes up the moment you start pricing raised beds, and the answer hinges on four things: how long the bed survives, how it treats the soil temperature, what it costs over its lifespan, and how it looks in your yard. Both materials grow vegetables perfectly well. The difference is in the years of service you get and the experience along the way.
Before you commit to a material, it helps to know what you plan to grow and when. A bed sized for shallow greens behaves differently from one built for tomatoes, and your fill-and-plant timing should line up with your local frost window. Run your ZIP through the planting calendar so the bed is full and warm by the time your crops want to go in.
The case for metal
Modern metal beds are galvanized or Aluzinc-coated steel, and they dominate the category for good reasons: they assemble in under an hour, they come in modular panels that reconfigure into rectangles and U-shapes, and a quality bed holds its finish for many seasons.
Vego Garden 17in raised bed
The Vego uses Aluzinc-coated steel, a zinc-aluminum-magnesium alloy that resists rust better than plain galvanized, especially at the soil line where moisture sits. The 17-inch height is deep enough for carrots and tomato roots while staying affordable to fill, and the modular panels solve real layout problems. It is the best all-around metal bed for most gardeners. You can check current pricing on the Vego 17in bed before deciding.
Olle 17in galvanized raised bed
The Olle targets the same 17-inch height and modular footprint at a lower price. The coating is conventional galvanized rather than the higher-end Aluzinc alloy, so long-term corrosion resistance is a small step behind, but for most gardeners in temperate climates that gap matters less than the savings.
Birdies 8-in-1 metal raised bed
Birdies is the Australian brand that arguably started the modern metal-bed trend, and owner reviews consistently mention beds holding their shape and finish after many seasons. The 8-in-1 panel system reconfigures into eight shapes. It costs more than the Vego or Olle, and that premium buys durability and configurability.
The case for cedar
Cedar is the right wood for a raised bed because it contains natural oils that resist rot and insects, so it lasts far longer than pine or fir without chemical treatment. That matters when you are growing food, because pressure-treated lumber is not something you want against an edible root zone.
Greenes cedar raised bed
The Greenes kit uses a slot-together dovetail design that assembles without tools and can be stacked for extra height. Cedar will silver and weather over time, and it will not last as long as a quality metal bed, but it stays cooler in direct sun and many gardeners simply prefer the natural look. It is the value entry point into cedar.
How to choose between cedar and metal
The decision usually comes down to four factors.
Longevity. Quality metal beds last the longest. Aluzinc steel is rated for a decade-plus, galvanized a bit less, and both outlast untreated cedar, which softens and breaks down over years. If buy-it-once durability is your priority, metal wins.
Soil heat. Cedar runs cooler than metal in direct sun. In temperate climates the difference is negligible because soil mass buffers temperature, but in very hot regions the edges of a metal bed can warm the root zone, so cedar (or heavy mulching on metal) has an edge.
Cost over time. Metal usually costs more upfront but less per year of service because it does not rot out. Cedar is reasonable for wood but pricier per year than a metal bed that lasts twice as long. Budget galvanized kits can undercut cedar on day one too.
Looks and feel. This is genuinely personal. Cedar reads warm and traditional and ages to a soft gray; metal reads clean and modern. Neither grows better vegetables, so trust your eye.
For depth, match the bed to your crops either way. Greens and herbs are happy in 8 to 11 inches, most vegetables including tomatoes and peppers want at least 12 inches, and root crops like carrots do best with 14 inches or more. A 17-inch bed covers nearly everything, which is why that height dominates the metal options here.

Frequently asked questions
Do cedar or metal raised beds last longer?
Quality metal beds last longer. Aluzinc-coated steel is rated for a decade or more, and galvanized steel is close behind. Untreated cedar is naturally rot-resistant but still softens, grays, and breaks down over years, faster where it stays wet. For longevity per dollar, metal is the better value over time.
Do metal raised garden beds get too hot for plants?
In temperate climates, no. The large mass of soil inside the bed buffers temperature swings, so the root zone stays stable. In very hot, sunny regions the soil right at the metal edges can warm up, but plants a few inches in are unaffected. Mulch heavily and water consistently if you garden in extreme heat. Cedar runs slightly cooler if heat is a real concern.
Is cedar safe for growing vegetables?
Yes. Untreated cedar is one of the safest bed materials because it resists rot through natural oils rather than chemical treatment. Avoid pressure-treated lumber for food crops. Galvanized and Aluzinc steel are also safe; the zinc coating is stable in soil and zinc is a plant micronutrient.
Is metal or cedar cheaper for a raised bed?
Budget galvanized metal kits and cedar kits land in a similar price range upfront. Over time, metal is usually cheaper per year because it does not rot out, while cedar needs replacing sooner. Premium metal beds cost more at purchase but spread that cost over many more seasons.
The bottom line
Choose metal if you want the longest service life, fast assembly, and modular shapes: the Vego is the best all-around pick, the Olle saves money, and the Birdies is the buy-it-once option. Choose cedar, like the Greenes kit, if you prefer a traditional look and a cooler root zone in a hot climate and you accept replacing it sooner. Whatever material you pick, get the depth right for your crops and time your fill so the bed is ready when your planting calendar says to plant.
