Update. Just checked the progress of my sago planted in paper bags. I can see some of them close to shore are indeed growing. The bags are still in place but fall apart easily when touched. Not all the bags ended up standing upright which was a concern for me since the idea was that the plant would grow out of the top of the bag. This doesn't appear to be a problem in that the plants are growing right through the sides of the soft bags. I'll try some time to get pictures but that's hard to do when the plants are 1 to 3 feet submerged.
