Thank you all for the excelent ideas!
I went ahead and purchased some deck posts and treated timber platforms (the ones used for the steps in deck stairs). I also got a manual fence hole digger (22 bucks at Lowe's, I wonder if renting a power fence hole drill would have been a better investment).
Will, once the monkey poles and platforms are in place, how do you secure the pots on top, do you use any wire or brackets? It can get very windy here in Corpus Christi and I can picture myself toopling them over in the early morning hours when watering my trees.
