Cedar is the best wood for raised garden beds — it’s naturally rot- and insect-resistant, food-safe, and lasts 7–10+ years with no chemicals. Redwood is the premium alternative; untreated pine is the budget pick but short-lived. Here’s how the options compare.
Best wood options compared
| Wood | Lifespan | Cost | Notes |
|---|---|---|---|
| Cedar | 7–10+ yrs | $$ | Best all-rounder — rot/insect resistant, food-safe |
| Redwood | 7–12 yrs | $$$ | Beautiful and durable, but pricey and regional |
| Douglas fir | 4–7 yrs | $$ | Mid-range; rots faster than cedar |
| Pine (untreated) | 2–3 yrs | $ | Cheapest; short-lived, good for a quick bed |
| Treated lumber | 10+ yrs | $$ | Lasts long but many avoid it for food (see below) |
Why cedar wins
- Naturally rot- and insect-resistant thanks to its oils — no sealing or chemicals needed.
- Food-safe — nothing harmful leaches into your soil.
- Stays cooler at the soil edge than metal in extreme heat.
- Widely available in pre-cut kits that assemble in minutes.

A word on treated wood
Modern pressure-treated lumber (ACQ / copper azole) is far safer than the old arsenic-based CCA, but plenty of gardeners still avoid it around food. If you do use it, line the inside with heavy plastic to keep it off the soil — or just choose cedar and skip the worry.
Wood vs metal
Wood looks natural and stays cooler, but metal lasts roughly twice as long with zero maintenance. See the full metal vs wood comparison, or browse all our best raised garden beds.
Frequently asked questions
What is the best wood for raised garden beds?
Cedar is the best choice for most gardeners — it's naturally rot- and insect-resistant, safe for food, and lasts 7–10+ years without chemicals. Redwood is similar but pricier; untreated pine is cheapest but only lasts 2–3 years.
Is treated wood safe for raised garden beds?
Modern pressure-treated lumber (ACQ/copper azole) is much safer than old arsenic-based CCA, but many gardeners still avoid it for food crops. If you use it, line the inside with heavy plastic to separate it from the soil — or choose cedar instead.
How long does a cedar raised bed last?
About 7–10 years, sometimes longer in dry climates. Redwood is similar. Untreated pine lasts only 2–3 years. For maximum lifespan with no maintenance, galvanized metal lasts 15–20 years.
Can I use pine for a raised garden bed?
Yes, but untreated pine rots in 2–3 years. It's fine as a cheap, short-term bed. Seal it or accept that you'll rebuild it sooner than a cedar bed.
