Brian, you have a good point, maybe put the peatmoss and dirt in, then zip tie a layer of fencing over it, but I would have to cut holes in it to put the plants in. If you started everthing from seed then you wouldn't have to make any holes.
I think with the height of the noodles and pipe on the outside it should keep the dirt and plant mass together, but if my pond was subject to high wind and wave action I would definitely put a layer of fencing over the top.
I'm also planning to put pvc across the frame to give it more strength.
