Add a Clematis Trellis to Your Boring Flat Fence

Turn that boring, flat fence into a living wall of vines with this easy to make clematis trellis! Customize your design and watch it fill with flowers!

Our tall fence provides plenty of privacy in our backyard, but isn’t exactly pretty. One side of the yard sports a trio of DIY garden trellises I built last year, and it worked out so well, I was inspired to create another one! This clematis trellis helps hide the fence behind a wall of greenery and flowers for just a few dollars!

This clematis vine has thrived along the base of the fence for years. The previous owner planted it without giving it anything to climb, so it functions more as a ground cover. Without support, the vine just sits in a pile on the ground! 

Starting from scratch with new vines? Here’s how to choose the best climber plants for your new clematis trellis!

I’m using the same cedar fence pickets as I did before, but this time I’m creating a more subtle pattern with the strips. You can change up the design to suit your style, or try one of these other DIY arbor and trellis ideas!

How to Build a Clematis Trellis

Cut the Trellis Pieces

If you’re using 6″ wide cedar pickets, rip them down into 1 ½” wide strips lengthwise. Don’t have a table saw? Just use 1 x 2 cedar boards!

Then, cut the 1 1/2″ wide strips into shorter pieces. Mine vary between 16″and 30″, so I can mix them up for a more random effect.

Give each piece a light sanding to remove splinters, but don’t remove all the texture. The clematis vines need something to grip onto! Stain each piece with exterior stain before starting assembly. 

Attach Trellis Pieces to Fence

Attach the longest pieces vertically and evenly spaced along your fence with brad nails. These slats hold the rest of the clematis trellis off the fence surface, so the vines can wind their way underneath and work their way up. (And yes, I probably should have power washed the fence beforehand. Just pretend the moss gives it a woodland garden effect!)

Pick a few longer pieces to go on the bottom horizontally. First, nail one end to the vertical support. Then use the level to make sure it’s straight before securing it in place.

Use the 1 x 4 spacer to keep the spacing between horizontal pieces consistent and to speed up installation. I love not having to reach for the measuring tape and level every time!

Decide on the placement of the next slat, then place the spacer on top of the piece underneath that spot. Add the new slat on top of the spacer and nail into place. 

Randomly place more horizontal pieces as you work your way up the fence, making sure each slat is attached to at least two vertical supports. If the gap between two verticals is too wide, add a few shorter ones in between.

As you work, step back and review your overall design. Make sure the spacing is consistent and the gaps between the horizontal pieces aren’t too big for the vines to reach. Pull off pieces and move them around if it’s not looking how you’d like. I went through a few different variations before I settled on this one!

Weave Vines Through Clematis Trellis

Weave the vines through the clematis trellis to give them a head start. If you’re planting new plants, they may only reach the first slat. Try using trellis ties to keep them in place. Clematis grows quickly, so the entire wall will soon be covered in blooms!

Now my clematis has room to spread and grow, instead of laying in a heap on the ground.

Plan out your garden ahead of time and and train those clematis vines early! This handy FREE printable garden planner will help you keep track of the seeds and plants you have or need, and the best time to plant them!

After I got most of the vines up on the fence, I pruned away the ones that were heading in the wrong direction or too far away from the fence. I gained back over a foot of space in the garden bed! I’m slowly reclaiming all the overgrown garden areas of the yard!

This area gets a lot of shade, especially in the afternoon when the sun goes behind the fence. I plan to add Fuchsia, Astilbe and a few ferns I divided to fill in the reclaimed space. These are some of my favorite flowering plants for shade gardens! I can’t wait to see it all filled in and blooming!
