Best Wood for Raised Garden Beds
Raised beds combine the planter box problem with a food question: many gardeners prefer to avoid chemically treated lumber around edibles, which puts naturally rot-resistant species front and center. The bed sits in permanent ground contact with damp soil inside, so the ranking favors woods with documented ground-contact durability at a price that works for a structure you may rebuild in a decade.
What matters here
Ground-contact durability
Species proven in fencing, decking, and ground contact hold up where the bed meets soil.
Naturally rot-resistant
Untreated but durable species sidestep the treated-lumber debate around food gardens.
Budget-tier bonus
Beds are big and simple; the cheapest durable wood is usually the right wood.

Deciding between two of these?
Before you buy
Thicker stock buys years: a 2-inch wall outlasts a 1-inch wall by more than double in ground contact.
Recommended joinery
Large, simple, in constant ground contact; joints are structural but plain, and everything must resist rot and be rebuildable.
Screwed butt joints (coated/stainless)
The standard raised-bed joint: fast, strong enough for soil pressure, and easy to replace a board when it eventually rots.
Corner posts
Screwing sides to a 4x4 corner post spreads the load and stiffens a long bed against soil bowing the walls outward.
Joint choice depends on the build more than the wood. Measured joint strength varies widely by wood, size, glue, and load direction, so these are ranked by suitability and reasoning rather than by a single strength number.
