How to Choose Trellises and Supports for Climbing Plants

Take Your Garden Vertical with the Right Supports

After a tour of British gardens, you’ll quickly appreciate how climbing plants transform a space. Roses clothe walls, clematis weaves through shrubs, and sweet peas dance up obelisks. Yet many U.S. gardeners miss out because they lack proper structures. Here’s a guide to selecting supports that are both functional and beautiful.

Key Considerations Before You Buy

Sturdiness is non‑negotiable. By midsummer a vigorous vine can weigh 50–100 pounds. Choose weatherproof materials—galvanized or plastic‑coated wire, painted or treated wood—especially for perennial climbers.

Decide on aesthetics. Do you want the support itself to be a focal point (an arbor marking an entry, an obelisk anchoring a path) or purely utilitarian? Decorative trellises can screen views, define boundaries, or simply add architectural interest.

Match the support to the plant. A climbing rose needs a different structure than a sweet pea; pole beans require something other than a tomato cage. For a deeper dive, see How Plants Climb.

Types of Supports: From Decorative to Functional

Walls

Few of us have aged brick walls, but a house wall, outbuilding, or neighbor’s fence can serve. Clinging plants like Boston ivy attach directly; most others need a wall‑mounted trellis or a wire/eye‑bolt system.

Decorative trellises add visual interest while supporting plants.

Arches and Arbors

These structures bring year‑round flair. Choose a style and scale that harmonizes with your home and landscape. Wood (painted or stained), steel, and plastic are all options.

Flat Trellises

Ideal for defining spaces or adding privacy. They can be freestanding or anchored to walls/posts. Wood lattice, metal panels, and plastic mesh are common examples. Their portability lets you experiment with placement.

A freestanding trellis creates a striking garden focal point.

Obelisks, Tripods, and Teepees

Both functional and decorative, these add strong vertical accents. Use them sparingly—like exclamation points. Ensure they’re tall enough: scarlet runner beans and vigorous morning glories need 8–10 feet. Bamboo canes make inexpensive, attractive teepees for vegetables.

Nearly Invisible Netting turns almost any surface into a climbing wall.

Fencing and Porches

Climbers adapt to almost any fence—chain‑link, post‑and‑rail, picket. Porch railings and banisters can be wrapped with plastic trellis netting.

Twiggy Branches (Pea Sticks)

A British favorite: free, quick to install, nearly invisible when covered, and compostable at season’s end. Collect 3–5 foot branches with plenty of fine twigs; shrub branches work best.

Cages and Ladders

Vegetable supports prioritize function: sturdy, durable, tall enough, and easy to store.

Growing Through Existing Shrubs and Trees

An English trick: let clematis scramble through a shrub or tree. Clematis ‘Henryii’ can climb a birch; canary creeper (Tropaeolum) weaves through hedges; passion vines also work in temperate zones.

Don’t let the Brits have all the fun. Combine a few of these supports with interesting climbers and take your garden to new heights.
