There are a few support sticks, but nothing in the way of organized cages or anything. I made a bunch of cages from fencing wire (cyclone sheep fence wire, not sure if you guys have that in the states). One of them had a store bought support cage, but it grew too heavy for it and toppled it over. They grow ok. The stems that lay horizontally put out roots, so they can increase their moisture/nutrient uptake when not held upright. I might get issues with air flow, but haven't yet. In the end, it was just a zero effort experiment, so the input effort has paid off so far. I don't water them or give them any care at all, other than maybe hacking them back when they grow over the path too much.
