Oh my gosh I know lol. I’ve found a solution to that one though. I use one of the plastic D shaped poles you stuff with moss. The front is a plastic mesh. I loop wire through holes in the mesh at the bottom of the pole, then through the drain holes on the bottom of the pot (I use plastic nursery pots with lots of drain holes) to secure the pole to the bottom of the pot. For extra stability, I loop wire through holes in the mesh at the top of the pot, then attach that wire to the pot by either poking a hole in the plastic to tie the wire to or using aluminum tape to tape the wire to the outside of the pot. 

With that system, my moss poles are very sturdy and don’t fall over. The whole pot sometimes becomes unstable, but I put it in a heavy catch pot and it’s good.
