Raspberry Trellis Systems

Thanks for all the details! It really helps. I especially like your flags on the anchors as I’m positive I’ll eat it. At the moment, I am planning on doing both floricane and primo, I left the cane from last year and they’re fruiting…we’ll see how long that lasts before I treat them like my elderberry and just do a big hack!

Question about the use of metal conduit. I’m making a trellis system over a sliding door and want to use it. It will be standing in 1’ concrete and about 7’ tall. Do you think 1/2” conduit will work or I need to go with 3/4”? Current plan is to grow passionfruit on it, so, not too heavy. I’ve never had a piece of the stuff around and once I order I’m pretty much stuck with it as I don’t have a way of returning 10’ pieces.

what cable gauge are you using?


Here is the set up I use for my blackberries.

I have a rather shocking amount of emt conduit… 1/2" is strong enough for a plant trellis. I have a Subaru Forrester and 10’ conduit fits in my car if I put in it diagonally.

This video will give you some more ideas about how strong it is:

Just finished the trellis for the blackberries.
55’ row sunk the 9.5’ hedge posts on the end 4.5’ into the ground used cheap (cheaply made too) 8’ t-posts every 7.25’, made the wire spreaders for the t-posts out of 1/2" rebar. Used double stranded, galvanized, 12 gauge, barbless barbed wire for the wire. Uses 2" angle iron from a scrapped irrigation pivot for the wire spacers on the hedge posts.

This video had an interesting blackberry trellis in the second half. It’s sort of cantilevered over to the side. He mentions in the video that he does U-Pick, could that be related? Or is it just to allow access to the tops of the very long blackberry canes without having to prune them?

(here is a still screenshot of the trellies for those uninterested in pulling up youtube, though it is easier to get a full understanding from the multiple angles shown in the video)

Anyone have thoughts on this style?

I assume they’re laid down like that to make covering them possible/easy. And covering doesn’t do much unless you heat or they’re close to the ground and trapping that air.

Ah! very clever then. Thanks for the insight.

Personally, I’d go with 3/4”. It’s not much more expensive. Id rather over build than under.

Thanks. I had already purchased the 1/2”.

Second. They have a lot of awesome ideas on their website when it comes to gardening. Last year I ordered what I need to build a bird netting frame over my container blueberry plants and need to get to that soon. The flowers are starting to appear.
