Build your own Raspberry Trellis from red cedar posts and 2×4’s. Complete animated build video that shows step-by-step how to make a support for your berry bushes. Grow berries on wood and galvanized wire supports.
See the How to Video.
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 2×4’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 2×4 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.
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.
A square 4×4 or a 6×6 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.
