Burrowing animals can reach a raised garden bed from below and damage roots before you see a problem. This step-by-step hardware cloth installation for raised garden beds explains how to choose the mesh, measure the footprint, cut safely, fasten each edge, and inspect the finished barrier. The method is useful for a new bed or an existing frame that still sits directly on soil.
Compare raised garden beds with an integrated animal barrier before building a DIY mesh liner.
A successful barrier is continuous, tight, and secured at the edges. It should cover the full area animals could reach, close the corners, and avoid exposed wire that could injure a gardener or catch on roots. The steps below focus on general DIY hardware-cloth work. They are separate from a purpose-built raised bed with a built-in animal barrier.
Why Put Hardware Cloth Under a Raised Garden Bed?
Hardware cloth beneath a raised bed creates a physical barrier between the surrounding soil and the root zone. It can help deter animals that travel below ground, including voles, gophers, and other small burrowing pests. A raised bed improves access and soil control, but its frame alone does not prevent an animal from approaching through the open ground underneath.
Hardware cloth is welded wire mesh. It is more rigid than chicken wire and is available with different opening sizes. The useful choice is the smallest practical opening that matches the pest risk and can still be cut, positioned, and fastened without leaving weak spots. Mesh selection is only part of the solution. A small opening at a corner or seam can undermine an otherwise strong liner.
Should the mesh cover the entire bottom?
When the bed sits directly on soil and burrowing animals are a concern, the mesh should cover the entire footprint. Extend it to every corner and fasten it to the frame or a surrounding structure. Do not rely on soil weight alone to hold down a loose edge. Animals can exploit a lifted corner, a gap at the frame, or a seam where two pieces meet.
When is a perimeter apron enough?
A perimeter apron may be appropriate when the bed already has a solid base, sits on a hard surface, or has a specific side-entry problem. An apron extends outward from the lower edge and blocks a route near the perimeter. It is not a substitute for a full bottom liner when animals can approach from beneath the entire bed. Above-ground pests such as rabbits and deer also require a different barrier strategy.
Tools and Materials to Gather Before You Start
Prepare the work area before unrolling the mesh. The cloth can spring back after it is cut, and its edges may be sharp. Keeping the tools close reduces unnecessary handling and makes it easier to complete a clean installation in one session.
- Hardware cloth: Choose welded wire mesh with an opening suited to the animals you want to exclude. Buy enough to cover the footprint and overlap seams where more than one piece is needed.
- Measuring tape: Measure the inside dimensions, outside dimensions, and any irregular corners. The measurement you use depends on where the mesh will be fastened.
- Marker or chalk: Mark cutting lines directly on the wire. Make the marks easy to see without placing your hands near an uncut edge.
- Wire cutters: Use cutters designed for the wire gauge. A clean cut is easier to fold, cover, and fasten than a crushed or jagged edge.
- Heavy work gloves and eye protection: Wear both while cutting and handling the mesh. Small wire ends can scratch skin or become airborne during cutting.
- Fasteners: For a wood frame, use corrosion-resistant staples or screws with washers that fit the material. For metal, choose fasteners compatible with the frame and avoid creating a sharp projection inside the bed.
- Hammer, staple gun, or drill: Use the tool required by your selected fastener. Keep the fastening method consistent around the perimeter.
- Landscape staples or ground pins: Use these for an apron or for temporary positioning. They should supplement, not replace, a secure frame attachment when the design allows one.
- Edge protection: Fold the cut edge, cover it with a durable strip, or position it where it cannot contact hands, plants, or garden tools.
Do not install mesh over an unstable or damaged frame. Repair loose boards, protruding screws, and soft wood first. A sound frame gives you a predictable surface for fastening and makes later inspections easier.
Step-by-Step Hardware Cloth Installation for Raised Garden Beds
Measure the area the mesh must protect, then add enough material for attachment and overlap. For a bottom liner, measure the length and width of the bed footprint at the surface where the cloth will sit. Add extra material on each side if the mesh will wrap up the inside of the frame or extend beneath a bottom edge.
1. Record the actual footprint
Measure both directions in more than one place. A frame may look square while having small differences between opposite sides. Record the longest measurement when a single piece must span the area. For an irregular bed, sketch the footprint and divide it into simple rectangles. Label each measurement before transferring it to the mesh.
2. Plan seams before cutting
Use one piece when it can cover the footprint without forcing the mesh to buckle. If the bed is wider than the roll, plan a seam in advance. Place the seam where both pieces can lie flat and be fastened to solid support. Add an overlap rather than joining edges end to end. The overlap should be wide enough to prevent a gap when the cloth shifts during installation.
3. Allow for folds and fastening points
If the cloth will rise along the inside of the frame, include that height in the cut. If it will wrap around an outside edge, include the full fold. Mark the intended bend lines so you do not cut away the material needed to hold the edge. A few extra inches used for a deliberate fold are more useful than a tight cut that stops short of the frame.
How Do You Cut and Position the Mesh Safely?
Put on gloves and eye protection before cutting. Lay the roll on a stable surface and weigh or clamp one end so it does not spring back. Mark the cut line with the mesh flat. Cut one wire at a time, keeping your free hand away from the line. After the cut, check for sharp points and remove or fold any end that could cause an injury.
Position the cloth with the cut edge facing a protected side whenever possible. For a bottom liner, center it so the planned folds or attachment tabs reach every side. Keep the mesh flat against the ground or frame. Wrinkles can create pockets where animals pry up the edge, and a high spot can interfere with the bed's level position.
Use a dry fit before fastening
Set the unfastened mesh in place and walk the perimeter. Confirm that each corner is covered, each planned fold reaches the frame, and each seam has the planned overlap. Adjust the piece now, before staples or screws make the position harder to change. This dry fit is also the best time to check whether the bed is square and whether an extra cut is needed around a post or bracket.
How Do You Secure Hardware Cloth to the Bed?
Begin at one side and work toward the opposite side, keeping the mesh tight without distorting its shape. Fasten the center of a long side first, then move toward each corner. This sequence helps hold the cloth in position while you check that it remains flat.
- Place the first edge: Align the cloth with the planned attachment line. Leave enough material for the fold or wrap, and avoid placing the edge where it can rub against a sharp frame corner.
- Make the first attachment: Add a staple, screw, or compatible fastener near the middle of the edge. Check that it grips the wire without tearing or crushing it.
- Work toward the corners: Pull the cloth just tight enough to remove slack. Add fasteners at regular, close intervals appropriate for the frame and fastener type. Do not stretch the mesh so hard that it lifts the frame or changes the footprint.
- Secure the adjacent side: Keep the corner closed while fastening the next side. Fold excess material neatly instead of leaving a loose flap that can be pushed aside.
- Close all corners: Check underneath and inside each corner. Add an attachment wherever the mesh can lift or where two folds create an opening.
- Fasten every seam: Overlap adjoining pieces and secure both layers. A seam is not finished until an animal cannot separate the pieces by pushing against the overlap.
- Protect the edge: Fold, cover, or turn away exposed wire ends. Run a gloved hand near, but not directly across, the edge to identify points that need correction.
Wood frames and metal frames need different fasteners
On a wood frame, staples or screws with washers can hold the mesh along a broad, solid edge. Place the fastener through the wire without leaving a large unsupported span. On a galvanized steel frame, use a fastener designed for the metal thickness and keep the cut wire from rubbing against the bed wall. Do not assume a wood staple will hold metal securely. If the frame design does not offer a safe attachment point, use a planned apron or another barrier method rather than forcing a weak connection.

How Do You Check the Finished Barrier?
A finished installation should pass a hands-on inspection before soil is added. Look for continuity, attachment, and safety. The mesh should cover the intended footprint without a visible opening at a corner, edge, fold, or seam.
| Inspection area | What to verify | Correction if it fails |
|---|---|---|
| Coverage | Mesh reaches every corner and covers the intended footprint. | Add material or reposition the liner before adding soil. |
| Edges | No edge can lift, fold open, or expose a path around the frame. | Add a compatible fastener and protect the cut edge. |
| Seams | Pieces overlap and both layers stay together when pushed gently. | Increase the overlap or fasten both layers to solid support. |
| Safety | No sharp wire ends, loose offcuts, or fasteners project into the bed. | Fold or cover the wire and remove debris before filling. |
Check coverage and gaps
View each side from above and below if possible. Confirm that the mesh reaches the frame on all sides and that no soil path leads directly around the liner. Pay particular attention to corners where excess material may have been folded back. Check seams from both directions. If you can slide a finger or tool through a gap, an animal may be able to enlarge it.
Check the fasteners and frame
Test each edge gently. The cloth should not pull away from the frame or shift enough to expose soil. Replace a loose fastener and add support where the wire bows away from the attachment line. Make sure the repair does not create a new sharp point inside the bed. The frame itself should remain level and stable after the mesh is installed.
Check for sharp wire and future movement
Cover or fold every exposed cut end. Remove loose offcuts from the soil and work area. Before filling the bed, consider how compost, stones, roots, and seasonal soil movement could press against the barrier. After a heavy rain, digging activity, or major soil movement, inspect the edges again. A barrier that was secure on installation day can become loose when the ground shifts.
DIY Hardware Cloth or an Integrated Animal-Barrier Bed?
DIY hardware cloth can be a practical choice when you already own a raised bed, need a custom footprint, or want to complete the barrier as a separate project. It also gives you direct control over the mesh opening, folds, seams, and fasteners. That flexibility comes with ongoing responsibility. You must make accurate cuts, close every edge, protect sharp wire, and inspect the installation after movement or damage.
Frame It All's animal-barrier garden beds take a different approach. The built-in mesh barrier installs directly into the garden joints, where it is designed to reduce openings between separate components. The barrier can also serve as a trellis and is intended to protect plants from rabbits, deer, and other garden visitors. The raised bed system uses the company's Snap-Lock bracket and board design, which is assembled with a hammer or mallet rather than a collection of screws and separate hardware.
The composite boards use a blend described by Frame It All as 38% recycled food-grade plastic and 62% sustainable hardwood fibers. The integrated design does not remove the need to inspect a garden bed, but it can reduce the number of custom mesh cuts, exposed edges, and hand-built seams involved in a retrofit. Read more about the integrated animal-barrier garden bed solution when deciding which approach matches your space.
Choose DIY hardware cloth when customization and the installation project are part of the plan. Choose an integrated bed when you want the barrier incorporated into the structure from the beginning. For another planning perspective, review this guide to garden beds with a built-in animal barrier.
Frequently Asked Questions
How do you line the bottom of a raised garden bed?
Measure the full footprint, add material for folds and attachment, and cut the hardware cloth with gloves and eye protection. Dry-fit it before fastening. Secure every edge, overlap and fasten seams, close the corners, and check for sharp wire or openings before adding soil.
What size hardware cloth is best under a raised garden bed?
Choose a welded-wire mesh opening based on the animals in your yard and the level of exclusion needed. Smaller openings can make access harder for small pests, but the mesh must remain practical to cut and attach. A complete, tight installation matters as much as the opening size.
How do you secure hardware cloth to a wood garden bed?
Position the cloth flat against a solid edge and use corrosion-resistant staples or screws with suitable washers. Start near the middle of one side, work toward the corners, and keep the mesh tight without stretching it out of shape. Protect or fold all cut ends.
Can hardware cloth be attached to a galvanized steel raised bed?
It can be attached when the bed provides a safe, compatible fastening point. Use fasteners suited to the metal thickness and keep cut wire away from hands, plants, and the inside wall. If the edge cannot hold the mesh securely, use a planned perimeter barrier instead of relying on soil pressure.
How often should you inspect hardware cloth under a raised bed?
Inspect it after installation and again after heavy rain, digging, major soil movement, or signs of burrowing. Look for lifted edges, separated seams, damaged wire, loose fasteners, corrosion, and new gaps. Repair the full weak area so the barrier remains continuous.
