Vines are an ideal addition to any garden or landscape, especially when grown and trained on trellises. There are several types of vines, ranging from berry vines, to rose bushes and vegetable vines. Keep some important things in mind when building a simple, functional grapevine trellis.
Decide what size you want your wooden posts to be (generally between 4-8 feet tall). Shorter ones are best for places with harsh winters. Eight-foot-tall trellises are ideal for any type of vine, as you can always add on height or width once it grows larger.
Pound two posts into the soil about 2 feet deep with the mallet, 3 to 4 feet apart. Space multiple sets about 10 feet apart.
Position the anchor post next to the main post, angling it away. Attach the heavy 12-gauge wire tightly between the main post and anchor. For a two- to three-post trellis, an anchor post at either end is fine. This will help keep the heavy 12-gauge wire taut.
Pull the heavy wire about 3 to 4 inches up from the ground along the length of the trellis. Run another length of the wire 1 foot up from this point. Secure the wires to the posts by wrapping them and positioning with clamps.
Use lengths of the lighter catch wire between the two lengths of heavier wire. Wrap the lighter wires around the heavy ones, spacing them several inches apart. These are to help train the vines and make pruning easier. Use pruning scissors to trim off any awkward angles or sharp ends.
Plant the vines right at the base of the main posts. Secure the main vine to the heavy wires with plant ties loosely. Wrap the vines or smaller branches around the catch wires.
