Building a garden trellis for your vegetables can help you better use precious space in your garden. Training vegetables to grow up instead of out will free up space for other plants. In the summertime, use the trellis to grow your favorite tomatoes and cucumbers. In the spring, add in pea vines to create green wall in your garden. Use the trellis to support rose bush vines mixed with creeping bean vines to create a magical focal point in your space. Add a set of outdoor garden lights around your trellis to light up the evenings.
Consider the crops you'll grow on your outdoor trellis. Heavy vine crops like squash and tomatoes will need a strong and heavy-duty structure to support the growing plants.
Remove all sod and debris in the area where your trellis will sit. Pull out weeds and vines that could potentially interfere with the vegetables. Smooth out the soil surface with a landscape rake, ideal for leveling out soil and garden spaces.
Pick out your trellis material. Hedge posts and tree branches can easily be found around yards, and they're strong and sturdy for growing vegetables.
Wet the wood to ensure it's pliable and bends easily. Sand down all rough patches and sharp edges on the hedge posts to prevent cuts.
Attach and secure the hedge posts together using large nails, which will guarantee a sturdy and strong trellis. Interweave the posts over each other and hammer nails into the middle of the cross-section. Repeat until you have a trellis that can stand straight and hold crops.
Dig a hole large enough so at least one-quarter to one-half of the hedge post is buried. Place the hedge posts into the hole and add soil and compost to the hole. Press down the soil to secure the trellis into the ground. For additional support, use heavy-duty garden wire and secure posts to a fence or garden wall.
Plant your vegetables at the base of the trellis and into the compost-laden soil. Water once a week for the first month for proper plant establishment.
