Thanks for the great input, guys. I will only be moving the large plants twice a year in and out of winter shelter. 4 of them will be on the deck with the new greenhouse someday. So they should be easy to move. In fact, I think most of the biggest pots are going to sit on the deck for ease and closeness to the projected greenhouse. But I like attaching the rope idea. Does one type of rope hold up better outside? Nylon? Cotton? Sisel?
