How to Build a Raised Garden Bed from Pallets

Pallet Raised Beds: Free Material, Real Results

Building a raised garden bed from pallets is one of the most popular garden DIY projects — and one of the most misunderstood. Done right, a pallet raised bed is a legitimate, productive growing space that costs almost nothing. Done wrong, it can introduce harmful chemicals into your soil and food. This guide shows you how to do it right: how to select safe pallets, build a sturdy frame, and set up a productive growing bed.

Pallet Safety — The Most Important Step

For a food-growing application, pallet safety is non-negotiable:

• HT (Heat Treated): Safe. Always use HT-stamped pallets for garden beds.
• MB (Methyl Bromide): Never use. This toxic fumigant can persist in wood and contaminate soil and food.
• EPAL/EUR: European standard, safe.
• No stamp or unclear: Do not use for food gardens.

Additionally, avoid pallets that have any staining, chemical odor, or unknown history. For a vegetable garden, only use pallets you're completely confident about. When in doubt, use the pallets for a flower bed instead of a food garden.

• Hardware Cloth / Wire Mesh — for the bottom (gopher protection)
• High-quality raised bed soil mix
• Cardboard — for sheet mulching the ground

Two Approaches to Pallet Raised Beds

Approach 1 — Whole pallets as walls: Stand pallets on their sides to form the walls of the bed. Fast, minimal work, very rustic. Best for a quick, temporary bed.

Approach 2 — Disassembled pallet boards: Pry apart the pallets and use the individual boards to build a proper raised bed frame. More work, but produces a much more refined, durable result. This guide covers both approaches.

Step-by-Step Instructions: Whole Pallet Method

Step 1: Select and Clean Pallets

Choose 4 matching HT-stamped pallets. Scrub with hot soapy water and let dry completely. Inspect for protruding nails and remove or hammer flush.

Step 2: Stand Pallets on Edge to Form a Square

Stand 4 pallets on their long edges to form a square or rectangle. The pallet slats become the walls of the bed. Connect adjacent pallets at the corners by driving 3" exterior screws through one pallet into the next. Use at least 3 screws per corner joint.

Step 3: Line the Interior

Line the inside of the pallet walls with landscape fabric, stapled to the pallet boards. This prevents soil from falling through the gaps between pallet boards while still allowing drainage. For extra protection, add a layer of hardware cloth at the bottom for gopher protection.

Step 4: Prepare the Ground and Fill

Lay cardboard on the ground inside the bed to smother weeds. Fill with raised bed soil mix (60% topsoil, 30% compost, 10% perlite). Fill to within 2" of the top of the pallet walls.

Step-by-Step Instructions: Disassembled Board Method

Step 1: Disassemble the Pallets

Use a pry bar to carefully remove boards from the pallets. Remove all nails. Sort boards by width and condition, selecting the best ones for the bed walls.

Step 2: Build Corner Posts

Cut 4 corner posts from the thickest pallet boards or from 4x4 lumber. Posts should be the desired bed height plus 6–8" to drive into the ground for stability.

Step 3: Assemble the Frame

Drive corner posts into the ground at the bed corners. Attach pallet boards horizontally to the inside faces of the corner posts using exterior screws. Stack boards to reach your desired bed height. Stagger joints between courses for extra strength.

Step 4: Line, Prepare, and Fill

Line the interior with landscape fabric. Lay cardboard on the ground. Add hardware cloth at the bottom if needed. Fill with quality raised bed soil mix.

Lining the Interior: Why It Matters

Lining the interior of a pallet raised bed with landscape fabric is important for two reasons:

• It prevents soil from falling through gaps between pallet boards
• It creates a barrier between the soil and the pallet wood, reducing the risk of any surface contaminants reaching your soil

Use a heavy-duty landscape fabric and staple it securely to the inside of the pallet walls.

Pro Tips

• Only use HT-stamped pallets for food gardens — no exceptions.
• Line the interior with landscape fabric to keep soil in and create a barrier between wood and soil.
• Add hardware cloth at the bottom if gophers or moles are present in your area.
• Use a metal detector before cutting pallet wood to find hidden nails.
• For flower beds, you can be less strict about pallet selection — the food safety concern is specific to edible crops.

Estimated Cost & Time

Materials: $5–30 (pallets often free; landscape fabric and soil are the main costs). Time: 2–4 hours. One of the most budget-friendly garden bed builds possible.

Final Thoughts

A pallet raised bed is a legitimate, productive growing space when built with safe pallets and proper lining. The key is being strict about pallet selection, lining the interior, and filling with quality soil. Do those things and you'll have a productive garden bed that cost almost nothing to build.
