Raised beds with legs are a game‑changer for small‑space gardeners. They save your back, fit nicely on patios or balconies, and let you control soil quality. But store‑bought versions can be expensive. I built my first elevated bed using two old pallets from a neighbor’s renovation project. It cost almost nothing, and it held up for several seasons with only basic maintenance.
If you want a practical, low‑cost, real‑world guide on how to build a raised garden bed with legs from pallets, here’s the method I’ve tested in my home garden. It’s simple, sturdy, and very beginner‑friendly.
Why This Pallet Raised Bed Method Works
Pallet wood is lightweight but strong, especially the thicker stringer boards. When used correctly:
- The legs stay solid under soil weight
- Slatted bottoms allow good drainage
- The bed lasts longer than expected (especially when kept off the ground)
- The cost stays extremely low
The biggest advantage is that pallets provide almost everything side boards, slats, and legs so you only need screws and a liner.
What You’ll Need
Most of this is free or inexpensive.
• Two safe, heat‑treated pallets (marked “HT”) • Pallet pry bar, hammer, or reciprocating saw • Drill + outdoor screws • Landscape fabric, burlap, or old feed bags • Measuring tape and pencil • Saw (hand saw or circular saw) • Bricks/pavers (optional but recommended)
Eco‑note: Only use HT pallets for edible gardens. Avoid pallets marked MB (methyl bromide).
Step-by-Step: How to Build a Raised Garden Bed With Legs From Pallets
1. Disassemble the Pallets
Use a pry bar or saw to remove pallet deck boards. Save:
- The flat boards (for the box and bottom slats)
- The thicker 2×3 or 2×4 pallet stringers (these become legs)
Tip from experience: Saw through nails instead of prying if boards keep splitting.
2. Choose Your Bed Size
For stability and easy building, aim for:
- Length: 3 to 4 feet
- Width: 18 to 24 inches
- Depth: 8 to 12 inches
Pallet wood isn’t ideal for very large raised beds because of soil weight.
3. Build the Box
- Lay out two long boards and two short boards.
- Screw them together to form a box.
- Use two screws at each connection.
Check squareness an uneven box makes wobbly legs.
4. Prepare the Legs
Cut four pallet stringers to equal length:
- For table‑height beds: 28–32 inches
- For shorter beds: 20–24 inches
Make sure cuts are even. Uneven legs = rocking bed.
5. Attach Legs to the Box
- Stand the box upright.
- Position one leg at each outside corner.
- Screw through the side boards into the leg use at least 3–4 screws per leg.
Sturdiness tip: Attach legs on the outside of the box, not inside. This supports weight better.
6. Install Bottom Slats
Soil is heavy never use a solid sheet of plywood.
Use several pallet boards:
- Space slats 1 to 1.5 inches apart
- Attach across the underside of the bed
- Add one or two support rails if the bed is longer than 4 feet
Proper spacing allows healthy drainage without losing soil.
7. Line the Inside
Use:
- Landscape fabric
- Burlap
- Old feed bags (poked with holes)
Staple or tack it inside the box. This keeps soil in place and reduces wood rot.
8. Set the Bed on Bricks or Pavers
This small detail doubles the lifespan of pallet legs by keeping them out of standing water.
9. Fill With Lightweight Soil Mix
A simple raised‑bed mix:
- 40% compost
- 40% topsoil
- 20% coco coir or peat
Avoid using heavy native soil; pallet beds aren’t meant for excessive weight.
10. Water, Test, and Plant
Water lightly to settle the soil. Check for wobble by pushing the sides gently. Add a diagonal brace if needed.
Expert Tips & Best Practices
• Add a cross‑brace between two legs to stop side‑to‑side sway. • Apply linseed oil to prolong wood life. • Keep bed depth shallow—pallet wood flexes if overfilled. • For balconies, use lighter soil blends and check weight limits. • Replace liners annually for best drainage and wood protection.
Common mistake: Overfilling with wet soil. Add soil gradually.
FAQ
Are pallets safe for vegetable gardens?
Yes if they are heat-treated (HT). Avoid chemically treated pallets (MB).
How long will a pallet raised bed with legs last?
Typically 2–4 years, longer if kept dry and lined well.
How deep should the soil be?
8–12 inches is enough for herbs, lettuce, dwarf tomatoes, peppers, radishes, flowers.
Can I build a pallet raised bed without power tools?
Yes. A handsaw, manual screwdriver, and hammer work just slower.
Will the legs hold the weight?
Yes, if made from pallet stringers and supported with multiple bottom slats.
When Not to Use This Method
Avoid pallet‑leg raised beds if: • You’re growing deep-rooted crops like full-size tomatoes, potatoes, or corn • Your soil mix is heavy and clay‑rich • You live in extremely wet climates where pallet wood rots fast • You need a very large or deep raised bed (use standard lumber instead)
Alternative Methods
• Use a plastic tote or storage bin on a pallet‑wood stand • Build a no‑leg pallet bed directly on the ground • Create a hybrid bed: pallet frame with purchased metal legs
These work well in tight spaces or where pallets are scarce.
Conclusion
Learning how to build a raised garden bed with legs from pallets gives you an inexpensive, practical way to grow food or flowers in small spaces. With one or two heat‑treated pallets, a handful of screws, and basic tools, you can build a sturdy elevated bed that lasts several seasons and keeps gardening easy on your back
