Whether you are planting ornamental vines or a vine crop such as peas, a trellis is a necessary support. In the case of ornamental plants, a trellis may keep the plants from burrowing their suckers into your home's masonry. Constructing a trellis requires just a few hours. The materials can be altered for the purpose and the aesthetic appeal. A well-constructed trellis ranges from cheap or free to moderately inexpensive depending on the materials you use.
Choose an area for your trellis. Erect the trellis in a full-sun garden bed for edible legume vines. Check the plant requirements for ornamental vines as they range from full-shade requirements, such as ivy, to partial sunshine types such as morning glories.
Measure the length of the garden bed to determine the length of the trellis. Plan a support every 4 feet along the length of the bed.
Purchase wooden stakes in the quantity decided by the length of your bed. Use 6-foot-tall stakes for edible vine plants and use the height of stake recommended on the seed packet or plant label for your ornamental vines.
Drive a stake 1 foot into the ground every 4 feet using a mallet. Drive the stake 18 inches into the ground if high wind is an issue in your area --- adjust the height of stake purchased to make up for the extra 6 inches.
Choose your trellis material. Use inexpensive chicken wire or concrete reinforcing mesh for edible vines where appearance is not as much of an issue. Use vinyl or wooden lattice trellis panels for ornamental vines. While more expensive, they are more visually appearing compared to metal mesh.
Cut the wire mesh to the length of your trellis plus 6 inches using wire snips. Most lattice panels come in 4-foot widths and require no cutting to size.
Staple the wire mesh to the supporting stakes with a staple gun. Space the staples 6 inches apart up the length of each stake. Nail lattice panels to the stakes, spacing the nails every 6 inches.
Plant your vines at the base of the trellis and guide them to the structure once they begin to grow. The vines will climb it on their own after the initial guidance.
