A fence for a raised garden bed keeps out rabbits, groundhogs, deer, and voles, and the best material depends on which pest you’re blocking and whether you want a permanent or removable barrier.
One wrong gap and the morning lettuce is gone. A fence for a raised garden bed solves that, but only if you match the material to the pest. Hardware cloth stops everything from mice to deer, while chicken wire works for general deterrence but fails against small burrowers. The sections below help you pick the right build—then show you exactly how to install it so nothing gets past.
Fence Material Options for Your Raised Bed
The first decision is what the fence is made from. Hardware cloth with 1/4-inch or 1/2-inch openings is the top all-around pick because its small mesh blocks mice and voles that slip through chicken wire. Welded wire fencing with 2×3-inch or 2×4-inch grids stops rabbits and larger animals but not tiny pests. Chicken wire is cheaper and lighter, but its larger openings and lower durability make it better for light deterrence than serious exclusion.
For the frame, cedar or composite wood is safer around edible plants than pressure-treated lumber, which can leach chemicals into the soil. Pressure-treated wood works fine for non-edible beds and privacy walls, but if the bed grows food, choose cedar. A permanent fence uses 2×2 treated posts with wire attached by heavy-duty staples; removable options use wood furring strips and plastic brackets so you can take it down for the off-season.
How to Build and Install the Fence
Measure the perimeter of the bed before buying any material, because a gap of even one inch defeats the whole barrier. Cut the fence material to length, set corner posts first, and stretch the mesh taut between them to prevent sagging. Attach the mesh to wood frames with heavy-duty staples; use zip ties or twist ties for plastic or metal frames.
The critical step for diggers is securing the bottom edge. Bury the lowest 6 inches of hardware cloth underground and bend it outward in an “L” shape. This prevents rabbits and groundhogs from tunneling under—the most common failure in raised-bed fences. For beds you access regularly, add a gate using hinges and a latch on one side so you can reach the crops without climbing.

Common Mistakes That Let Pests Through
Using chicken wire when the real problem is mice or voles is the single most common error, because the mesh openings are too large for small rodents. Failing to bury or anchor the bottom edge leaves a gap animals push under overnight. Leaving the fence loose instead of taut creates pockets that reduce both protection and durability, and choosing decorative screening instead of real wire mesh guarantees disappointment when a groundhog walks right through it. Each one is easy to fix once you know to look for it.
Which Pests Need Which Fence
The right fence for a raised garden bed depends entirely on what you are keeping out. Small openings stop small pests; tall fences stop deer. This table matches the material to the problem:
| Pest | Recommended Material | Special Installation |
|---|---|---|
| Mice and voles | 1/4-inch or 1/2-inch hardware cloth | Bury bottom 6 inches, bend outward in L shape |
| Rabbits | 1/2-inch hardware cloth or welded wire (2×3 inch) | Bury bottom 6–12 inches; keep fence at least 2 feet high |
| Groundhogs | 1/2-inch hardware cloth | Bury bottom 12 inches; L-bend is essential |
| Deer | Tall welded wire or plastic netting (5+ feet) | Height matters more than mesh size; can use PVC frame |
| General deterrence | Chicken wire (light duty) | Anchored at ground; not for small rodents or persistent diggers |
FAQs
Do I need to bury the fence around a raised bed?
Yes, if you have digging animals like rabbits or groundhogs. Burying the bottom 6–12 inches and bending it outward in an L shape stops them from tunneling under, which is the most common failure point for raised-bed fences.
Is chicken wire good enough for a raised garden bed fence?
Chicken wire is adequate for light deterrence of larger animals, but its openings are too big for mice and voles, and the wire is less durable than hardware cloth. For serious pest protection, use 1/2-inch or 1/4-inch hardware cloth instead.
Can I use pressure-treated lumber for a raised garden bed fence?
Pressure-treated wood is fine for fence frames around non-edible beds, but avoid it near edible crops because chemicals can leach into the soil. Cedar or composite lumber is a safer long-term choice for food gardens.
