So Wes, you have a good selection of tomatoes yourself. Not as long as my list but we all know I am slightly nuts!
Anyway, yes I do use those green coated Metal Fence Posts I buy at Home Depot. I don't put them as stakes for each plant but make rows so I can Florida Weave. And I have other types of cages around here also. I use a combo of things.
This year will Florida weave many plants as I just didn't have cages to support all those plants that I bought.
