How to Make a Metal Garden Trellis

Overview

Many garden plants, such as indeterminate varieties of tomatoes, pole beans or pea plants can benefit from being tied to a trellis. Growing vegetables on a trellis provides a vertical space for plants and allows for better circulation and access to light. Trellised plants produce ripe fruit faster than plants with no trellis. Trellising these plants allows you to make more efficient use of space in your garden. Shorter plants such as marigolds or basil may be planted in between the garden plants through intercropping to crowd out weeds and provide pest control. One of the sturdiest trellises that you can create is one made of metal.

Step 1

Drive posts into your garden at 20 foot intervals. The tops of the posts should be approximately 6 feet above the ground.

Step 2

Stretch barbed wire across the top of the fence posts. Twist the wire twice around each end of the posts and then wrap the loose end of the wire three times around the stretched wire before cutting.

Step 3

Stretch a second wire along the base of the trellis, 1 foot above the soil line.

Step 4

Plant your plants beneath the row of wire.

Step 5

Stretch twine between the two rows of wire. For beans or other climbing plants, wrap the plant around the twine as it grows. Clip tomatoes or other plants that require support but do not twine using greenhouse tomato clips or polythene plant ties.
