How to Make a Cheap Trellis: DIY Projects Under $20 for Climbing Plants

Climbing plants like beans, cucumbers, and roses need support—but buying trellises can be expensive. These seven budget-friendly DIY projects cost under $20 and use materials you likely already have, perfect for small gardens or urban containers.

Bamboo Sticks and Twine Trellis

Bamboo Sticks and Twine Trellis

Transform your garden into a rustic haven with a bamboo sticks and twine trellis—the perfect solution for supporting lightweight vines like peas, beans, or cucumbers while keeping costs under $10. This natural, biodegradable trellis requires just a handful of bamboo stakes (available at garden centers or hardware stores) and sturdy twine, making it an eco-friendly choice that seamlessly blends into any garden aesthetic.

Start by driving 4-6 bamboo stakes into the ground in a square or rectangular formation, spacing them about 12 inches apart to create a sturdy frame. Next, weave the twine diagonally between the stakes in a crisscross pattern, securing it tightly to form a lattice. For added stability, tie the twine around each stake at least three times before moving to the next. This trellis is ideal for small gardens, containers, or urban balconies, where space is limited but you still want to maximize vertical growth.

Gardeners who love minimalist, organic designs will adore this trellis—it’s easy to assemble, requires no power tools, and can be disassembled and reused year after year. Plus, the natural materials break down safely in the soil when their time is done. 🌱

PVC Pipe and Chicken Wire Frame

PVC Pipe and Chicken Wire Frame

When your garden features heavy climbers like cucumbers or pumpkins, you need a trellis that won’t sag under the weight. A PVC pipe and chicken wire frame delivers the strength and customization to support these sprawling plants without breaking the bank or your back.

Start by cutting PVC pipes into vertical posts (4-6 feet tall) and horizontal supports. Wrap chicken wire around the pipes to create a lattice structure—this combo handles 50+ pounds of fruit while staying lightweight. For extra stability, anchor the base with stakes or bury the pipes slightly. The wire can be adjusted as vines grow, making it perfect for seasonal use or long-term support.

This trellis is ideal for gardeners with limited space or those who prefer a clean, modern look over rustic materials. Plus, the materials are reusable year after year, saving you money and reducing waste. 💪

Wooden Dowels and Zip Ties

Wooden Dowels and Zip Ties

Tired of bulky trellises hogging space in your balcony or windowsill? Wooden dowels and zip ties are the secret weapon for container gardeners—turning a simple pot into a stylish, adjustable support system for herbs like basil or thyme or delicate flowers like nasturtiums.

Start by cutting dowels (¼-inch thick) to your pot’s height, then crisscross them inside the container. Secure the intersections with zip ties, leaving gaps wide enough for vines to weave through. The beauty? You can adjust spacing as plants grow, and the dowels blend seamlessly into any decor. For extra stability, anchor the base to the pot’s rim with a few more ties.

This method is perfect for urban gardeners or anyone with limited space—it’s lightweight, affordable, and lets you grow upward without sacrificing floor room. Plus, the clean lines make it a stealthy upgrade for small-space aesthetics. 🌿

Turn trash into treasure with a zero-cost trellis that’s perfect for kids or fast-growing pole beans! This project uses empty plastic bottles and string to create a lightweight, temporary support system that’s both eco-friendly and endlessly customizable.

Start by cutting plastic bottles into 1-inch horizontal strips (remove labels first). Weave them into a lattice pattern around two sturdy vertical sticks or a wooden frame, securing with string or twine. For extra stability, add diagonal supports—ideal for 6-foot-tall plants like beans or cucumbers. The lattice can be adjusted as plants grow, making it perfect for small spaces or container gardens.

This trellis is a hit with budget-conscious gardeners and families teaching kids about sustainability. Plus, it’s completely biodegradable at the end of the season! 🌱

Metal Coat Hangers and Wire

Transform your household clutter into a charming trellis for roses or clematis—no trip to the garden center required! Metal coat hangers and wire create a sturdy, rustic frame that’s perfect for small gardens or urban containers, all while keeping costs near zero.

Start by bending 3-4 hangers into a circular or oblong shape, then secure them with garden wire (or even floral wire) to form a grid. For extra stability, hammer a few nails into a wooden post or fence as anchors. This trellis supports heavy climbers like roses while adding a vintage touch to your garden. Paint the hangers for a pop of color or leave them silver for a metallic contrast.

This project is ideal for small-space gardeners or anyone looking to reduce waste. The rustic charm blends beautifully with cottage-style gardens, and you’ll have a trellis ready in under an hour. 🌷

Straw and Twine Vertical Garden

Straw and Twine Vertical Garden

Turn your garden into a vertical feast without breaking the bank by transforming straw bales into a biodegradable trellis. This rustic method is perfect for growing edible climbers like peas, beans, or even cucumbers—while adding a charming cottage-garden aesthetic to your space.

Start by stacking 2-3 straw bales vertically, securing them with twine or jute rope to create a sturdy frame. Plant your seeds directly into the bales or use them as a support structure for nearby plants. The straw’s natural texture provides grip for vines while breaking down over time, enriching the soil. For extra stability, lean the bales against a fence or wall.

This method is ideal for small-space gardeners or those who want an eco-friendly, temporary solution. Plus, kids love helping with the planting—making it a fun, hands-on project for the whole family. 🌱

Old Ladder and Chicken Wire

Old Ladder and Chicken Wire

Turn that rusty old ladder from the garage into a vertical garden powerhouse—no more clutter, just more growing space! This DIY trellis is perfect for heavy climbers like grapes or kiwi vines, transforming limited areas into productive green walls.

Wrap the ladder’s rungs with chicken wire (secured with zip ties or wire twist ties) to create a sturdy lattice. The wire’s flexibility handles weight while allowing vines to twine naturally. Lean the ladder against a fence or wall, or prop it vertically in a corner—no digging or permanent installation needed.

Urban gardeners and small-space growers will love this zero-cost solution that maximizes vertical space. Plus, the ladder’s weathered charm adds rustic character to your garden. 🌻
