What Is a Trellis?
A Trellis is a vertical or angled garden structure that supports climbing plants and adds height to a planting area. Trellises may stand alone or attach to a wall, fence, or raised bed. Common materials include wood, metal, and composite products. The open frame guides stems while allowing light and air through.

Key Takeaways About Trellis
- A trellis has an open frame for climbing plant support.
- Strong anchoring keeps the structure stable as plants grow.
- A trellis isn't the same as a solid fence or privacy screen.
How Trellis Works
Trellis works by giving climbing plants a frame for stems, leaves, and tendrils to follow. The frame may use a grid, slats, wires, or another open pattern. Gardeners guide young growth toward the support as the plant develops.
Designers check the trellis height, width, material, and connection points. The base must suit the soil and nearby paving. A wall-mounted trellis needs a secure attachment and enough space for plant growth. A freestanding model needs stable support at its base.
A climbing plant may cling, twine, or need ties as it grows. A privacy screen blocks views more fully, while a trellis keeps an open structure that plants can cover over time.
Expert Note
When we plan a trellis, we check the plant's growth habit, mature weight, and available support. We also review nearby walls, paving, and planting soil before choosing the structure and its connection points. Our team places the trellis so plants have room to grow without blocking paths or windows.
Trellis in Practice: A Real-World Example
For a residential garden design, a trellis can sit behind a planting bed with a climbing vine trained across its frame. The structure adds height and seasonal interest while keeping the bed open near a walkway.
