I'm building an arbor/ trellis and am wondering if anyone can give me suggestions how to build this thing. I have attached a basic sketch of the dimension of what I'm going for. On the right hand side I drove some t-poles into the ground. So far I tied some 2x4s with wire to two of them. My question is should I plant the 2x4s in the ground instead? These are pressure treated 2x4s. If so how deep would it be necessary to prevent the collapse of this thing? I was estimating 12" deep though I could go as deep as 18" and still have enough board left over to equal 6.5' on top. Only problem is digging that deep turns into more and more rocks. So if anyone is pretty handy please advise.

Thanks for looking!
