How to build DIY fence trellis?

[NewHomeOwner]

Hi all, 
I am about to undertake a DIY fence trellis that will not be a permanent fixture on our fence.  
The distance between our fence and perimeter concrete is 0.395m. I am planning to use 90*90mm posts, cut to 1.98m in height. 

I don't want to set the post directly into the ground; instead I would like to use anchors. Can you please advise me how deep the hole for the anchor should be, and what the required diameter would be also. 

Thank you in advance.

Hi @NewHomeOwner,

Welcome to the Bunnings Workshop community, it is fantastic to have you with us.

Being that it is a trellis, which will allow wind to pass through it, so you won't experience the same lateral wind loads that you would with a standard fence, you should be ok using post anchors concreted in place.

I would suggest using these Pryda 300x90mm M10 Full Stirrup Post Anchors with a 600mm deep hole, 300mm in diameter.

Let me know what you think and if you have further questions, please don't hesitate to ask.
