How to Build a Wooden Tomato Trellis: Step-by-Step Instructions
This DIY wooden trellis is simple to build and doesn’t require complex woodworking skills. You’ll construct two identical panels and connect them with a dowel hinge, allowing for foldability and easy storage.
🔨 Step 1: Drill Anchor Holes
Take all four 5-foot wooden stakes and drill a hole about 5 inches from the flat (top) end. Use a 3/8-inch or 7/16-inch drill bit, depending on availability.
Tip: If the dowel doesn’t fit snugly, wrap fine-grit sandpaper around a pencil and gently sand the inside of each hole until the dowel slides in firmly but smoothly. This will serve as the pivot point for your foldable trellis.
📝 Step 2: Mark Crossbar Placement
Lay two of the wooden stakes flat on the ground, with the holes you just drilled facing outward.
Using a tape measure and pencil, mark the following positions:
- First mark: 12.5 inches down from the top
- Then: Make three more marks, each 7.5 inches apart moving downward
These marks indicate where the bamboo crossbars will be installed.
🔩 Step 3: Install Bamboo Rails
On each of the marks, gently hammer in a small galvanized nail—these will act as mini “shelves” for your horizontal bamboo stakes.
Space the two stakes about 4 feet apart, then lay one 4-foot bamboo stake across each pair of corresponding nails to create a simple ladder-like structure.
🔧 Step 4: Secure Bamboo with Glue and Twine
- Place a small dot of hot glue where each bamboo crossbar touches the wooden stake to keep it from shifting.
- For extra durability, wrap a short length of twine tightly around the joint where bamboo meets wood.
Repeat this process for all bamboo bars. Now, you’ve completed one side of the trellis.
🔁 Step 5: Build the Second Trellis Panel
Repeat Steps 2–4 to construct the second identical panel using your remaining two wooden stakes and bamboo stakes.
You should now have two matching frames, each reinforced with crossbars and twine.
Final Assembly: Creating the Foldable Frame
Once both panels are complete, it’s time to join them together with the wooden dowel to form a stable, collapsible A-frame trellis.
🔗 Step 6: Insert the Dowel and Assemble the Frame
- Lay the Panels Flat:
Place one panel bamboo-side down (this will be your back panel). Lay the second panel bamboo-side up on top of it, aligning the tops so the drilled holes match up. - Insert the Wooden Dowel:
Carefully thread the 3/8-inch wooden dowel through the drilled holes on both pairs of stakes.- Tip: It should be a tight fit. Twist the dowel as you go, or gently tap it through using a dead-blow hammer if needed.
- If it feels loose, secure it with a bit of hot glue or wrap with twine at the ends.
- Spread the Panels Apart:
Once the dowel is in place, stand the structure upright and gently spread the bottom ends apart to form a stable A-frame. The depth is adjustable, so you can set it to fit your garden space (typically 2–2.5 feet apart at the base).
Step 7: Installing the Trellis in Your Garden
With the frame fully assembled, it’s time to place your trellis where it will do the most good.
🌿 Installation Tips:
- Insert the stakes directly into the ground, raised bed, or planter box by pressing or gently tapping the pointed ends into the soil.
- Make sure the frame is level and sturdy. The dowel hinge and dual-panel design offer great balance and multiple anchor points.
- As your tomato vines grow, weave them through the bamboo crossbars, or loosely tie them with garden twine to help them climb and stay supported.

🌱 Frequently Asked Questions (FAQ)
❓ What type of tomatoes need a wooden trellis?
If you’re growing indeterminate tomato varieties, such as cherry, heirloom, or beefsteak tomatoes, a wooden tomato trellis is an absolute game-changer for your garden. These plants don’t stop growing until frost hits, often reaching heights of six feet or more. Without proper vertical support, they’ll sprawl along the ground, becoming more prone to pests, diseases, and reduced airflow. That’s where a sturdy, foldable wooden tomato trellis steps in—lifting your vines up and off the soil, encouraging healthier fruit production and easier harvesting.
Whether you’re growing in raised beds or containers, using a trellis tailored to your plant’s growth habit is essential. For more inspiration, check out our roundup of 5 easy tomato trellis ideas that offer creative ways to support climbing varieties. You can also explore vegetables to grow for beginner gardening to pair your tomatoes with compatible crops. A strong wooden tomato trellis isn’t just helpful—it’s one of the best investments you can make for indeterminate tomato success.
❓ Can I adjust the size of this trellis?
Absolutely! One of the best features of a wooden tomato trellis is how customizable it is to your garden’s unique layout. Whether you’re working with compact containers on a patio or spacious raised garden beds, you can easily tailor the trellis to suit your needs. If you’re planting in tighter spaces, you can trim the height or narrow the width to keep things tidy without compromising support. On the flip side, if you’re growing in a larger bed, you can expand the frame and even add extra vertical stakes for reinforced stability.
Thanks to the clever folding-frame design, you can also adjust the depth of the structure to optimize airflow and access to your plants. This flexibility makes it a smart solution for gardeners who need adaptable infrastructure across different spaces or growing seasons.

The process involves basic tools like a drill, hammer, and tape measure, making it friendly for beginners and experienced DIYers alike.
To streamline the build, consider organizing all your supplies ahead of time, cutting stakes to size, and pre-marking your measurements. That little bit of prep work can significantly reduce assembly time and make construction smoother.

❓ Is this trellis strong enough for large tomato plants?
Yes! The combination of wooden stakes, bamboo crossbars, and twine reinforcement creates a strong, stable structure ideal for tall, heavy tomato vines.
❓ What’s better: a wooden trellis or a metal tomato cage?
Wooden trellises are more customizable, easier to store, and budget-friendly, while metal cages are bulkier and often more expensive. For indeterminate tomatoes, wooden trellises offer better long-term support and airflow.
