Russ, my pond is currently full and at about 5 feet deep. In a normal wet spring it would overflow and probably be 6 feet deep. Since my pond is just a hole in the ground I know that as the summer progresses the water will get shallower but I don't know how low it might get. I don't think mine will dry up but it could easily go down to two feet. You have burr reed? Do you know what kind? Are in interested in selling some roots?
Bill, maybe I will go out and take some tubers out of the sunken bags and manually bury them. Because I know my water level will drop considerably over the summer I have a dilemna as to how deep to plant the tubers. I really felt that I had better plant some of them in at least 3 feet of water so when the level goes down I don't lose them. So I planted at varying depths from 2 feet to 4 feet. I assume the plants will die if they come out of the water. Is that true? I have used the nail method before with some water celery I planted but I think the ducks found them before they grew and I lost them all.
