Looking to boost your garden’s productivity while keeping things tidy? This adjustable garden trellis is the perfect weekend project.
Built from small lumber and string, it helps train cucumber, pea, or bean vines upward, saving space and reducing the risk of rot. It’s efficient, compact, and surprisingly simple to make.
Why This Plan Works
- Space-saving design – Vertical growth allows more plants in smaller areas.
- Prevents rot – Keeps cucumbers and other vegetables off the damp soil.
- Improves harvest visibility – No more missed or overripe vegetables hiding under leaves.
- Simple materials – Built with standard 2x2s and 1x2s, plus string.
- Adjustable and reusable – Use year after year for different climbing crops.
- Optional paint customization – Add a pop of color to your garden beds.
What You Will Need
Tools
- Table saw
- Drill with bits
- Tape measure
Materials
- Two 2x2x8′ boards
- Three 1x2x8′ boards
- Two 1/4″ x 3.5″ bolts
- Two 1/4″ washers and nuts
- Screws or nails
- String
- Paint or stain (optional)
Step 1. Cut and Prepare the Legs
Take the two 2x2x8’ boards and cut them each in half to make four legs, each four feet long.
Use a drill to add holes to each leg as indicated in your reference drawing.
Step 2. Cut the Slats
Next, cut the 1x2x8’ boards into three sections, each 32 inches long.
You’ll end up with multiple slats—these will serve as horizontal supports.
Step 3. Clean Edges and Add String Slots
Clamp the slats together and run them through the table saw lightly to ensure smooth, even edges.
Then, using the saw blade set to 1/8″ height, cut small notches across each slat to hold the vertical string later.
Step 4. (Optional) Paint Your Pieces
For a colorful garden accent, now’s a great time to paint or stain the wood pieces. Painting before assembly makes the process cleaner and easier.
Step 5. Assemble the Legs
Using screws or nails, assemble the cut legs as shown in your reference.
This creates two A-frame-style sides that will support the slats and string.
Step 6. Bolt the Legs Together
Join the two leg frames by drilling through their tops and connecting them with the 1/4″ bolts and wing nuts. This makes the trellis foldable and adjustable in width.
Step 7. Attach the Slats and String
Place the slats across the legs and secure them. Then thread the vertical string through the slots you cut earlier. For added support, weave a few diagonals to help climbing plants find their way.
Note: Adjust the spacing between slats and strings depending on the plant type you plan to grow.

Summary
This adjustable garden trellis is a practical and efficient solution for supporting cucumber, pea, and bean vines. By lifting the plants off the ground, it boosts yield, minimizes rot, and keeps your garden organized.
