That's interesting, Julie but I rooted my dragon fruit cuttings laying flat on the ground. It probably doesn't matter as long as you have some part of where they make roots in contact with the soil.
Are you going to separate those four plants once they start growing? It might get pretty crowded in that one pot! The stems get big and fat once they start elongating. Main stems of mine are over 2in. across.
Here it is climbing to the top of my 6ft. fence. Second shot is another one climbing up the trunk of an oak tree (it needs more light). Third shot is a stem node with aerial roots coming out. I could just break off that piece and start a new plant by laying it down so those roots touched soil or a tree branch, even. I had another shot that was too blurry, of a piece of that same plant that broke off in a wind storm and sat on top of the fence, where it has taken root and started growing all of its own accord.
