It’s an easy trellis design based on the popular raspberry trellis T post system.


Build the Raspberry Trellis

The Sketchup Model

The cedar fenceposts I had were 8 footers and I cut slots in them for the cross members.

The slots are 12 and 36 inches from the top.

Cross Members

The cross members that support the wires are made from cedar 2x4’s. And are 36 and 24 inches long.

The post is buried 2 feet in the ground.

On the back, I cut a groove 5 feet from the top for a brace.

It’s also made from a cedar 2x4 and will be buried.

Construction of the Raspberry Trellis

On some sawhorses in the garden, I layout the cuts for the cross members.

And cut those to length.

Marking cross member centers

I mark the center of each and drill a hole for the carriage bolt that will secure it to the post.

I mark the two slot locations for the cross members.

Mark to posts for notches

A square 4x4 or a 6x6 would work for a post as well. I roughly square the upper cross member and mark lines for my saw cuts. I make the first two cuts into the post.

Post Notching

As the posts are round and irregular, I use a level to help guide the cuts so they are somewhat parallel. I have some wedges under the post to keep it from rolling around.

I used a pencil line marked on my saw as a depth gauge so my cuts were somewhat consistent.

I knock out the wood with mallet and chisel. I only made two saw cuts as this wood is soft and easy to remove.
