How to Make a Raised Garden Bed Cheap: DIY Frames Using Pallets and Wire Mesh

Turn pallets and wire mesh into a cheap raised garden bed that outlasts store-bought kits. 🌱 I built mine last spring using scraps from the hardware store discard pile and a roll of galvanized mesh—no fancy tools, no expensive lumber. The best part?

It’s deeper than most kits, holds soil better, and you can customize the size to fit any space. This design skips the pricey cedar boards by using untreated wood pallets (check local businesses first—they often give them away) and reinforces the corners with wire mesh instead of screws.

A single bed costs less than half what you’d pay for a pre-made frame, and the mesh keeps critters from digging underneath. You’ll need basic tools: a drill, staple gun, and gloves—nothing that isn’t already in your garage.

By the time you’re done, you’ll have a 12-inch-deep bed (ideal for root crops) that stays weed-free and drains perfectly. The mesh also doubles as a built-in trellis for vining plants like cucumbers or beans. Plus, it’s light enough to move if you need to rotate crops next season.

The whole project takes under 2 hours, and the materials last for years. Whether you’re working with a tiny balcony or a backyard corner, this method proves you don’t need a big budget to grow big harvests. Let’s get building!

Step-by-step instructions for building a budget-friendly raised garden bed

Here's how to create sturdy, affordable raised beds using repurposed materials—no fancy tools required.

Start with 4 wooden pallets (clean, untreated wood only) and 1 roll of heavy-duty wire mesh (½-inch grid). Pallets should be at least 3 feet long—shorter ones will make the bed too narrow for most plants. Use a screwdriver, hammer, and nails (or screws if you prefer) to assemble everything.

Check pallets for splinters or chemical stains (look for green or black marks). If you find treated wood, skip it—those chemicals can leach into your soil. Sand down any rough edges with 100-grit sandpaper to prevent splinters. I like to lay the pallets flat and mark where the corners will meet with a pencil before cutting.

Cut two pallets lengthwise down the middle to create 8 long sides (use a circular saw or ask a hardware store to cut them for free). You'll need four 3-foot lengths for the outer edges and four 2-foot lengths for the inner supports. This creates a 3-foot by 2-foot bed—perfect for most vegetables.

Lay two 3-foot sides parallel on the ground, then attach the 2-foot supports at each end using 2-inch deck screws (one at each corner). Pre-drill holes to prevent splitting. Stand the frame upright and check for square corners by measuring diagonally—both sides should be equal. If not, adjust the screws until it's perfectly even.

Unroll the wire mesh and cut a piece to fit the inside of the frame, leaving a 2-inch overhang on all sides. Bend the mesh upward along the edges and secure it with staple gun staples every 6 inches. This keeps the wood from bowing outward as the soil fills the bed and prevents roots from escaping.

Real talk: The mesh might look flimsy, but it does the job. I’ve had these beds hold up for 3+ years with no warping. If you’re worried, add a second layer of mesh on the bottom half of the frame for extra support.

Line the bottom with cardboard or landscape fabric to block weeds, then fill with a mix of ½ yard compost, ½ yard topsoil, and a 5-gallon bucket of perlite for drainage. Leave 2 inches of space at the top for mulch. Water everything thoroughly before planting.

Plant your greens and root crops along the edges where they’ll get the most light. I like to add a slow-release fertilizer (like 10-10-10) mixed into the top 2 inches of soil for an instant nutrient boost. Avoid heavy feeders like tomatoes—they’ll outcompete smaller plants in this size bed.

Water deeply 2-3 times per week, aiming for 1 inch of water total. Raised beds dry out faster than in-ground plots, so check the soil 1 inch down—if it’s dry, it’s time to water. Mulch with 2 inches of straw to retain moisture and suppress weeds.

Every 2-3 years, refresh the soil by removing the top 4 inches of old mix and replacing it with new compost. This keeps nutrients high without overloading the bed. I also add a handful of worm castings annually to boost microbial activity.

Tips & tricks for building a budget-friendly raised garden bed

These practical tricks will help you build a sturdy, long-lasting raised bed without breaking the bank—or your back.

Material Selection: When choosing pallets, look for ones with slats that are 2-3 inches wide—this creates more surface area for roots to spread. Avoid pallets with nails sticking out (they can puncture your gloves and soil bags). If you can't find untreated pallets, cedar or redwood pallets are often chemical-free and naturally rot-resistant. I've used pallets from local hardware stores that cost just $5 each—way cheaper than buying lumber.

Cutting and Assembly: Mark your cutting lines with a pencil and a straightedge before using the saw—this prevents uneven cuts that can make your frame wobbly. For the 2-foot inner supports, position them 6 inches from the ends of the 3-foot sides to create a stable rectangle. I use a level to check the frame's square before screwing it together, which saves time fixing crooked corners later.
