How to build a garden trellis

Step by step article about how to build a garden trellis. In order to build the simple trellis and to attach it to the house wall, rip pieces of 2×2 cedar from wooden boards. Afterwards, you should use arrange the components in a nice grid, making sure they are perfectly square. Check out the rest of my plans and tutorials for more building inspiration.

Last but not least, you should place spacers to the back of the trellis, to leave enough space for the vines to grow and climb. In order to get the job done in a professional manner, you have to secure the trellis to the wall, using galvanized screws. Plumb the trellis with a spirit level, if you want to get a professional result.

In order to build a garden trellis, you need the following:

 

Materials

  • 2×2 lumber – SLATS
  • 1×2 trellis – SPACERS
  • 2-3” screws – DECKING SCREWS
  • 5” screws – SCREWS
  • wood stain – VARNISH

 

Tools

 

Tips

  • Smooth the edges of the wooden boards, with a router
  • Pre-drill holes in the wooden components, before driving in the screws
  • Countersink the head of the screws
  • Don’t use lumber that is likely to crack or shrink
  • Don’t over-tighten the screws to prevent the wood from splitting

 

Time

  • One day

The first step of the project is to build the first layer of 2×2 slats, equally spaces. As you can see in the image, two slats are longer, as compared to the others, as they will be the legs of the trellis. Adjust the size of the trellis, according to your needs.

Smart Tip: Make sure the slats are equally spaced at both ends. The distance between the slats could range from 5” up to 15”, according to the climbing plants you are going to grow.

Afterwards, you have to install the cross slats, making sure the corners are square. Use a framing square to make sure the corners are right-angled. Work with great care and attention, if you want to obtain a professional result.

Smart Tip: We recommend you to place the slats on a sturdy surface, otherwise the end result might not raise up to your expectations. Smooth the edges of the slats, using a sand block.

 

Installing the spacers

Installing the spacers

 

In order to secure the slats together, you should drive in 3” galvanized screws. Nevertheless, you should leave enough space for the plants between the trellis and the wall.  The spacers will leave enough room for the vines to climb.

Smart Tip: Cut 1” spacers from 1×1 slats and place them on the joints, as in the image. Drill pilot holes, to prevent to wood from splitting, before driving in the decking screws.

The next step is to lock the trellis into place. Therefore, drill several pilot holes trough the wooden slats and insert the screws, using a screwdriver. Plumb the trellis with a spirit level, before locking in into place.

Smart Tip: You don’t need to insert many screws in the wall, as in most of the cases 8 screws are enough to secure a medium-sized trellis into place. If the plants need more space to grow properly, you could cut larger spacers.
