If you're wanting to add a little visual interest to your garden, try building a garden trellis. It's as easy as 1-2-3.


Our friends at have simple directions for creating a garden trellis in one afternoon.

What you need:

  • 6 (10-foot lengths) 2 x 2 cedar (for verticals) ***Note: You can change the size of the trellis to suit your needs, but be sure to have your lumber cut accordingly.
  • 9 (8-foot lengths) 2 x 2 cedar (for horizontals)
  • 2 large balls of green twine
  • Wooden finials (optional)
  • Powdered gypsum (or flour)
  • 6 (4-inch) tomato plants
  • Measuring tape
  • Shovel or post hole digger
  • Mallet or hammer
  • Scissors

Step 1: Take the measurement 

  • Select a flat, level location and clear out any debris. Measure the length and width to suit your particular space, then mark the four corners with gypsum or other powder.
  • Mark the midpoint on each long side with more dots of powder. You will now have the outline of your trellis and the points where posts will go.

Step 2: Hammer and Shape

  • Loosen the soil where dots are marked with a sharp shovel to a depth of 1 foot for each post. Using a mallet -- or even a large rock -- pound the vertical posts into the ground.
  • Measure 1 foot down from the top of each vertical post, and then tie opposite sides together to make three teepee shapes.

Step 3: Tie It Together

  • With strong twine and sturdy knots, tie the horizontal rails at 2-foot intervals on each side of vertical posts. Snuggle the remaining horizontal post into the crossed pieces at the top of the trellis, and secure. Screw-on wooden finials for a final flourish.
