I think it sounds, like others have said, like hang up central!!!

What I would do - if I had those materials, is grab a bucket or two (see if anyone around you has cats - they might by cat food in big buckets) -

Take the lattice, and pull it apart - use the pvc and the wood slats from the lattice - stand them up in the bucket and fill the bucket 1/2 way up with quickcrete - let it set, then drop it in...
