whatisa trellis

A trellis is a simple framework that lets plants grow vertically instead of sprawling along the ground.

Basic definition

• A trellis is an open framework or lattice made from wood, metal, plastic, or similar sturdy materials.

• It is designed specifically to support climbing plants and vines as they twine, cling, or lean on it.

• The structure is usually placed upright against a wall or fence, or freestanding in a garden.

What a trellis does

• Helps plants like beans, peas, cucumbers, and flowering vines grow upward, saving ground space.

• Improves air circulation around foliage, which can reduce fungal problems such as mildew.

• Adds visual interest and can create focal points or living walls in a garden.

• Can offer a bit of privacy when covered with dense greenery or flowers.

Common uses and types

• Garden trellis: Sturdy decorative structure for vines, flowers, or vegetables in beds or containers.

• Wall or flat trellis: Mounted on a wall or fence so plants can climb and soften blank surfaces.

• Teepee or A-frame trellis: Cone or tent-like shape, often used in vegetable gardens for beans and similar crops.

In short, when people ask “what is a trellis,” they’re usually talking about that grid-like garden structure you see covered in roses, ivy, or vegetables, giving plants support and gardens a vertical, architectural look.
