So with grow bags and adding more bark and pumice, I think I could get them from staying too wet. (We are really humid and rainy.) I could pop them into pots or on saucers if they dry out too much in the summer, but I usually water everyday if it gets hot and dry. I am planning on just keeping them in bags for 1 season...but I'll have to see.
Grow bags did not work for me with potatoes, so I can use them with peonies, yeah!
