How to Build a DIY Garden Trellis

How to make a DIY garden trellis with PVC

7-Step DIY PVC Trellis

I don’t know about you, but my garden has just been growing like crazy! I have waited to put in a trellis for my beans and peas because I have been working on other projects and have been busy harvesting all of the berries that are ripening right now!

Anyway, I finally got around to making a DIY garden trellis for my bean plants and sugar snap peas. The peas have been trying to vine for a few days, and the beans are just getting there so I knew I had to get going on it quick.

Frugal living and frugal gardening has been a goal of mine this year, so I really like when I am able to do a DIY garden project! I wanted to share my project with you so you can see just how easy and inexpensive it is to make a PVC trellis in your own garden.

What you’ll need to make your DIY garden trellis:

(**Below I will tell you the amount and measurements of each material that I used based on the measurements of my garden boxes. You will need to make adjustments based on the measurements of your boxes.**)

  • 1/2″ PVC Pipes (I needed 4: $6.88)
  • 1/2″ Elbow joint PVC Connectors (I needed 8: $2.24)
  • 1/2″ Two Hole Conduit Straps (I needed 8: $2.18)
  • 1 1/4″ Screws (I already had these.)
  • Garden Twine ($2.98)
  • PVC pipe cutter or hack saw (I already had this.)
  • Drill with drill bit & Philips head bit (I already had this.)
  • Total cost for my trellises: $14.28!! I had originally thought about getting a metal one, but they were over $40 each, so this works really well for me! ๐Ÿ™‚

Step 1:

Gather materials and mark off measurements on PVC pipe. I wanted (3) trellises to sit 36″ high and 42″ wide & (1) trellis 48″ high and 42″ wide so marked them as following:

  • Pipe 1 – 36″, 36″, 48″
  • Pipe 2 – 36″, 36″, 48″
  • Pipe 3 – 42″, 42″, 36″
  • Pipe 4 – 42″, 42″, 36″

Step 2:

Use pipe cutter or hack saw to cut the pipes. **Use extreme caution and follow directions on how to use the cutter or saw!!**

Step 3:

After I cut the sections, I laid them out in the garden according to where I wanted them to go:

Step 4:

Pre-drill holes into the inside of the garden box and screw the conduit straps down just a little bit. Slide the (height section) pipe into the conduit strap.

Once the pipe is in place you can fasten the strap tightly. Repeat this step for all pairs of trellises that you are wanting to make.

Step 5:

Slide the Elbow joint connector onto the top of the height section of pipe. Once you have the elbows on, take the width piece and attach them together.

Step 6:

Cut pieces of garden twine and tie them onto the pipe so they hang down to the plant. I ended up measuring out one of the pieces and then used it as a guide and pre-cut several pieces so that I could work a little faster.

Step 7:

Gently wrap the plants around the twine to help guide them, or wrap the twine around a rock and place it on the soil if your plants are not ready to vine yet.

Your DIY Garden Trellis is Finished!

There you go!! This project took me about an hour from start to finish and tying the twine and wrapping them around the plants was the most time-consuming thing.

The nice thing about using twine is that at the end of the season you can just cut off the pieces at the top and have a quick garden clean up for your vine plants!!

  • Have you planted bush variety or climbing variety of the peas and beans? If they are climbing, is this tall enough for them?
    *New Gardener*

    • Hi Jill!
      The peas are a bush variety, but they’ll still need a little help growing up, so that’s why the trellis is a bit shorter. Last year for my pole beans I used a wooden trellis that was 5′ high. I started with the shorter option but have the opportunity to add on to it with a T bracket and have it keep going up if needed.

  • Dude, can’t you just borrow the saw, or use some sticks for the trellis? That seems like a better way to make money.
