A trellis is simply a devise that allows plant vines to grow vertically instead of growing along the ground. It doesn’t have to be anything fancy or expensive to build, just use things found around the house or yard that will support the weight of the plant, even a fence line can be the trellis.
Old pallets make great trellis-building material. There are many ways to make a trellis from old pallets, so let your imagination flow.
Gather your materials and tools. You will need safety glasses (safety first), an old pallet, wood stakes or scrap sticks or wood pieces that can be pounded into the soil, screws, a drill with a screw driver bit and a small drill bit to pre-drill for the screws if necessary.
For this purpose, I chose a basic stake trellis.
Lay the pallet on the floor or work table, so that the face of the pallet is down. Lay one of the stakes on the bottom board. If I were building this pallet trellis to go outside in the ground, I would screw the stake into the board, so that it would go into the soil as far as possible. You can cut any excess wood away from the stake if desired, but this is optional.
Drill a pilot hole into the stake (if necessary), and then screw the stake onto the pallet. My trellis will be lightweight and only used indoors, so only two screws were necessary on each stake, but make your trellis as secure as you need.
Place the trellis in the area of your container or garden desired. Use a mallet to pound the stakes into the ground if necessary, or dig a hole for the trellis and back-fill around the stakes.
Plant your vining plants and train them to grow and weave in and out of the trellis.
Also an excellent way to grow string beans indoors!
