How to Make a PVC Tomato Trellis


The tomato plants are getting bigger, yet I still couldn’t bring myself to buy those flimsy, pre-made tomato cages that are available at all the hardware and garden stores. Instead Joe and I put our brains and supplies together to create beautiful and functional tomato trellises for half the cost of the cages.

Some supplies we bought, and some we had on hand… but I have no doubt anyone can find things laying around their own yards to improvise this easy DIY trellis project. It was so easy and cheap that we are going to duplicate this project for our beans, squash and cucumbers later in the summer when they demand our attention.


  • 1 inch thick PVC

  • 2 ft Lengths of Rebar

  • String

  • Spray Paint (optional)


  1. Cut PVC into 3 – 5 foot lengths depending on the expected size of your tomato plants. We used a circular saw, but you can use a number of tools to do this.

  2. Drill holes straight through each piece of PVC beginning 8 inches off the ground and spaced about 1 ft apart.

  3. Spray paint your favorite color.

  4. Use a mallet to drive the rebar into the ground in the row of tomatoes where you plan to place your PVC posts. Rebar should be spaced 3 – 6 ft. apart, leaving 1 ft. of rebar above the ground.

    Once the paint is dry:

  5. Drop the PVC posts onto the rebar

  6. Beginning with the top hole, weave string, twine, or wire through the PVC holes, img_20180701_102357tying off the string to each row’s end piece. If your string is difficult to get through the holes, use tape on the end of the string.

  7. Repeat with the remaining rows of holes.

    For additional plant support:

  8. Cut 8 in. lengths of twine

  9. Loosely tie plants to the horizontal trellis strings.

  10. Appreciate the job well-done!

As the tomatoes grow, I cut the twine and re-tie supports as necessary. This system stores easily and can be used each year for tomatoes, beans, cucumbers, squash or any climbing plant. It adds a beautiful vertical feature to your vegetable garden while supporting our favorite garden delights.


Please let us know how this works out for you. I will share more pics of the growing garden soon. Happy building!
