A trellis is a functional, yet decorative, feature in a vegetable garden that supports climbing vines as they grow upward. It can be made from a variety of material in different shapes, sizes and forms to fit the space available and complement the surrounding area. Depending on personal taste, build a bamboo tepee trellis for lightweight vegetables such as peas and beans, or a criss-cross trellis for zucchini or tomato crops that are heavier and require a sturdy support.
Clear out the area where you want to install the trellis from stones, rocks and plant debris and dispose of these items. Make sure the spot meets the sunlight requirements of your crop. Rake the surface to smooth it out.
Cut each of the four bamboo poles 6-feet in length with a handsaw to form a single tepee trellis.
Demarcate a 4-foot wide circle over the selected spot, and mark four equidistant points over the edge. Space other identical trellises 4 feet apart.
Insert one end of a bamboo pole 1-foot deep in the ground, directly over a point on the edge of the circle. Angle the pole inward so it meets the tops of the other poles, forming a tepee. Insert the remaining three poles over the other three points, and hold all the tops together.
Wind a length of garden wire 6 inches from the tips of all the bamboo poles. Secure it so it does not come loose.
Wind garden wire around a bamboo pole, a foot below the previous one. Extend it to the adjacent pole, and loop it around firmly. Do not cut excess off, but weave it to the next pole and wind it around it firmly before reaching the last pole. Loop the wire around it once before cutting excess length off. This row of garden wire supports growing tendrils.
Wind length of wire the same way until you reach the base of the bamboo poles. Space the rows of wires a foot apart from each other.
