This has been discussed on the list before, but not recently, so it's worth repeating: If you're in the US, an excellent source for tall plastic pots is Stuewe & Sons, https://www.stuewe.com/ They supply a bewildering variety of tall pots to the tree nursery industry, and also racks to hold them upright. You've got to order in quantity (something like a hundred at a time), but I've bought from them and was pleased. My only complaint: The pots I got were not designed for long duration use. Mine started to become brittle after a few years in the sun. I spray-painted some of them with white paint on the outside as a sun-blocker, and that helped a lot.
