Recommended material for Grape vine trellis post

Have some grape wines planted last autumn, that i plan to train along post. Than when they grow a bit more i will make a trellis for them (with 2 wires).

Now, wondering about which material to use for the post ?

Initial post i plan to be only 1 meter above the ground. Than when grape wine reach above 1 meter, than i would train them over lower trellis wire.

Plastic post are easy to find (aluminum post coated in plastic), and they are not too thick, perfect.

But i would like something more sustainable, if i can figure it out.

Looking for suggestions. Thank you.

I have some black locust tree trunks in different diameters, that i could use, but wondering what would be the right diameter ?

Also, raw spruce lumber is available to buy, which i can make into posts.

    What country are you in? Do you have termites that eat wooden posts?

  • Do not have termites at all.

    If you can find post made from douglas fir they are great, very rot resistant

    Can you give more info @daca34948? Are you in the UK?
    I don't really understand what you're trying to do though - have you got a photo or two of the site as well?
    I've never seen aluminium posts covered in plastic either. If growing outside, most people would use 3 to 4 inch timber fence posts, fixed into the ground, with trellis or wires for training and supporting, just as you would for any climber or similar, but I'm not sure what you mean about training the vines over the lower supports once they get bigger. 
    It's a place where beautiful isn't enough of a word....



    I live in west central Scotland - not where that photo is...
