If you’re tired of rabbits, deer, or groundhogs eating your vegetables, a fenced in raised garden bed is the answer. It combines the benefits of raised beds (better soil, drainage, and easy access) with a protective barrier. This guide walks you through planning, building, and maintaining your own fenced raised garden, including pro tips, material choices, and common pitfalls. Whether you’re a beginner or experienced gardener, you’ll find actionable steps to create a durable, pest-proof garden.
Why Choose a Fenced In Raised Garden?
A fenced in raised garden offers several advantages over traditional in-ground or unfenced raised beds. First, it physically blocks most common garden pests like rabbits, deer, and even some birds. Second, it helps contain your soil and mulch, reducing erosion. Third, it can act as a support for climbing plants like beans or cucumbers. Finally, it adds a tidy, organized look to your yard. The key is to build it correctly from the start to avoid wasted time and materials.
Step-by-Step: How to Build a Fenced In Raised Garden Bed
Follow these steps for a sturdy, long-lasting fenced raised bed.
Step 1: Choose the Location and Size
Select a flat, sunny spot (at least 6–8 hours of direct sunlight). Common bed sizes are 4x8 feet or 4x4 feet. For the fence, add about 2 feet of height above the bed for most pests, or 4 feet for deer. Plan a gate on one side for easy access.
Step 2: Build the Raised Bed Frame
Use rot-resistant wood like cedar or redwood, or use galvanized steel or concrete blocks. Avoid treated lumber with chemicals that may leach into soil. Assemble the frame with screws or brackets. For a 4x8 bed, use 2x6 or 2x8 boards, stacking them if you want a deeper bed.
Step 3: Install the Fence Posts
Set wooden or metal posts at each corner and every 4 feet along the sides. Dig holes 18–24 inches deep, add gravel for drainage, then set posts in concrete or tamped soil. Ensure posts are plumb and level. Let concrete cure for 24 hours.
Step 4: Attach Fencing Material
Use 1/2-inch or 1-inch hardware cloth (galvanized wire mesh) for small pests, or chicken wire for larger ones. Staple the mesh to the posts, bury the bottom edge 6 inches into the ground to prevent digging. For deer, add a second layer of taller fencing (4 feet high) or use a plastic deer fence.
Step 5: Add a Gate
Build a simple wooden or wire gate using the same material. Attach with hinges and a latch. Make sure it fits snugly to prevent gaps.
Step 6: Fill and Plant
Line the bottom with landscape fabric to block weeds, then fill with a mix of topsoil, compost, and peat moss (or a pre-mixed raised bed soil). Plant your vegetables or flowers, water well, and mulch.
Materials Comparison: What to Use for Your Fenced Raised Garden
Choosing the right materials affects durability, cost, and maintenance. Here’s a breakdown:
Wood (Cedar, Redwood, or Untreated Pine): Cedar and redwood are naturally rot-resistant and last 10–15 years. Pine is cheaper but will rot in 3–5 years unless sealed with a natural oil (avoid chemical sealants). Cost: $50–$150 for a 4x8 bed.
Galvanized Steel: Very durable, rust-resistant, and modern-looking. Kits are available, or you can build with corrugated steel panels. Cost: $100–$200.
Concrete Blocks: Inexpensive and long-lasting, but can be heavy and raise soil pH slightly. Cost: $30–$60.
Fencing: Hardware cloth (1/2 inch mesh) is best for all-around protection. Chicken wire (1–2 inch mesh) works for larger pests but may let in small rodents. Plastic netting is cheap but degrades in sun. Cost: $20–$50 for a 4x8 bed.
Pro tip: Use stainless steel staples or screws to avoid rust. Also consider adding a top rail to keep the fence rigid.
Common Mistakes to Avoid (Beginner Pitfalls)
Even experienced gardeners make errors. Here are the top ones:
- Not burying the fence: Many pests will dig under. Always bury the mesh at least 6 inches deep, or extend it outward in an L-shape at the base.
- Using too small mesh: 1-inch chicken wire will not stop small rabbits or voles. Stick to 1/2-inch hardware cloth for ground level.
- Forgetting a gate: You need easy access for weeding and harvesting. A gate also makes it easier to move wheelbarrows in and out.
- Overlooking height: Deer can jump 6 feet. If deer are a problem, make your fence at least 4 feet high, or use a slanted top.
- Using treated lumber: Old pressure-treated wood contains arsenic and copper, which can leach into soil. Use untreated or naturally rot-resistant wood instead.
- Poor post anchoring: Wind and weight can topple flimsy posts. Set them in concrete or use metal ground spikes.
Real Buyer Tips for Fenced In Raised Garden Kits vs. DIY
If you prefer a kit, look for one that includes both the raised bed frame and fence panels. Brands like Greenes, Gardener’s Supply, and Vego Garden offer good options. Check that the metal is galvanized and the wood is cedar or composite. Kits cost $200–$500 but save time.
For DIY, you can save 30–50% and customize size. Total cost for a 4x8 foot fenced raised bed with cedar and hardware cloth is around $150–$250. Tools needed: saw, drill, staple gun, shovel, level.
Pro tip: Add a row cover or shade cloth over the top to protect from insects and birds without blocking light. Also consider drip irrigation inside the bed to reduce water waste.
Frequently Asked Questions
Q: Do I need to line the bottom of a raised bed?
A: Yes, landscape fabric helps prevent weeds and burrowing pests. But if you have gophers, add a wire mesh bottom before filling.
Q: Can I use PVC pipes for the fence?
A: PVC is not sturdy enough for a permanent fence. Use metal or wood posts.
Q: How deep should the raised bed be?
A: At least 12 inches deep for most vegetables, 18 inches for root crops.
Q: Will a fence keep out all pests?
A: No, but it stops most. For flying insects, use row covers. For squirrels, add a roof.
Conclusion
A fenced in raised garden is a smart investment for any home gardener wanting to protect their plants without harsh chemicals. By following the steps above—choosing the right materials, burying the fence, and avoiding common mistakes—you’ll enjoy a productive, low-maintenance garden for years. Start with a small bed if you’re unsure, and expand as you gain confidence. Happy gardening!
