Raised garden beds are a popular choice for growing vegetables, herbs, and flowers. But without proper fencing, your hard work can be undone by rabbits, deer, groundhogs, or even your own pets. This guide will help you select the right fencing for your raised beds and install it correctly to keep your plants safe.
Why You Need Fencing for Raised Beds
Animals see your raised bed as an all-you-can-eat buffet. Deer can jump over low fences, rabbits can squeeze through small gaps, and groundhogs can dig under. Fencing protects your investment and ensures you get a harvest. It also defines the garden area and can deter children or pets from trampling plants.
Choosing the Right Fence Material
Common materials include:
- Hardware cloth (galvanized steel mesh): Best for small animals. Use 1/4-inch or 1/2-inch mesh to keep out rabbits and rodents. It’s sturdy and lasts years.
- Chicken wire: Inexpensive but flimsy. Works for chickens but not for determined rabbits or deer. Use only as a temporary solution.
- Welded wire: Stronger than chicken wire. Choose 2x4-inch mesh for larger animals. Good for deer if tall enough.
- Plastic or vinyl netting: Lightweight and easy to install, but degrades in sunlight. Best for temporary or seasonal use.
- Wooden pickets or bamboo: Aesthetic but expensive. Requires maintenance. Use for decorative or semi-permanent fences.
For most raised beds, hardware cloth or welded wire is the best balance of durability and cost.
How to Install Fencing on Raised Beds
Follow these steps for a secure installation:
- Measure your bed: Determine the perimeter and height needed. For deer, fence should be at least 4 feet tall. For rabbits, 2 feet is often enough.
- Choose attachment method: You can staple the mesh to the inside of the bed frame, attach it to wooden posts driven into the ground, or use PVC pipe hoops for a removable cover.
- Cut the mesh: Use wire cutters or tin snips. Wear gloves to avoid sharp edges.
- Secure the bottom: Bury the bottom edge 6 inches into the ground or bend it outward in an L-shape to prevent digging. For raised beds with a solid bottom, you can skip this.
- Attach to frame: Use heavy-duty staples (for wood) or zip ties (for metal or PVC). Space fasteners every 6-8 inches.
- Add a gate or access: If the bed is large, create a simple door using a wooden frame and hinges. Or make the fence removable by attaching with clips.
Common Mistakes to Avoid
- Using mesh that’s too large: 2-inch mesh won’t stop baby rabbits or voles. Stick to 1/2-inch or smaller for small pests.
- Not burying the fence: Many animals dig. If you don’t bury or anchor the bottom, they’ll tunnel under.
- Making the fence too short: Deer can easily jump a 3-foot fence. Go at least 4 feet, or 6 feet if deer pressure is high.
- Ignoring the top: Some animals climb. A top cover (like bird netting) may be needed for squirrels or raccoons.
- Using untreated wood that rots: If attaching to wood, use pressure-treated lumber or cedar, or use metal posts.
FAQ
Q: Can I use electric fencing for raised beds?
A: Yes, but it’s more complex. Use a low-impedance charger and warn family/pets. It’s effective for deer and raccoons.
Q: How do I keep my fence from rusting?
A: Use galvanized or stainless steel mesh. Avoid cheap uncoated wire. If rust appears, apply rust-resistant paint.
Q: What’s the cheapest option?
A: Chicken wire is cheapest but not durable. For a low-cost long-term solution, buy hardware cloth in bulk.
Q: Do I need to fence all sides?
A: If the bed is against a wall or building, fence the exposed sides only. But animals can climb walls, so consider a top cover.
Final Tips for Success
Before buying, check local wildlife. If deer are common, invest in a taller fence. For rabbits, focus on small mesh and buried edges. Always check your fence monthly for holes or sagging. A well-built fence lasts for years and saves you from replanting. Happy gardening!
