Decorate Your Fence with a Custom Trellis from PVC Pipe

As I was working on this project, I started paying attention to fencing as I drove around my community.

While the most common fences are wood, composite, iron or chain-link, fencing options are as broad and individual as the yards they contain. The best-looking fences, however, are usually softened and enhanced with shrubs, perennial plants and pretty flowers.


I incorporate the same principles of design on exterior projects as I do interior ones: paying close attention to contrast, variety and scale.

Since most fences are around four feet tall, adding something taller will make them more interesting. A trellis is the perfect solution. It’s sculptural, yet practical. Plant a climbing flower and in a few weeks, you’ll have a colorful layer of texture and pattern.


I decided to build my own trellis out of PVC piping. I like PVC because it’s lightweight, easy to work with and an unexpected material in a garden. Start with a drawing so you know exactly how much you need when shopping. I decided on a 6-feet-high x 2-foot-wide trellis.

PVC pipe comes in many sizes and widths. For my purpose, 3/4 inch is plenty big enough. PVC pipe is sold in 10-foot lengths. Unless you have a really long trailer, you’ll have to ask the store to cut it for you for the drive home.


I bought three 10-foot pipes and had the store cut off four feet from each. When I got home, I did a few more cuts.


I also needed:

  • 2 elbow connectors (fittings)
  • 5 tee connectors
  • 2 cross tee connectors

When building your trellis, be sure that you purchase connectors in the same size as the pipe (3/4 inch) and double-check that you’re buying socket connectors, not threaded connectors.


From each 6-foot length, I cut two 18-inch pieces, leaving a 36-inch piece for the vertical bars. From two of the 4-foot lengths, I cut six 12-inch pieces. These are the horizontal bars. I laid them out on the floor and put everything together like a puzzle. I used PVC pipe cement to bond the connectors and fittings to the pipes to ensure the entire piece stays upright and together.


Dig a small hole and stick the trellis into the ground next to your fence. Use wire, a clamp or a pipe grip tie to attach the trellis to the fence. Then, plant your favorite climbing flower or vegetable at the base. In a few months, your fence will be the envy of the neighborhood.
