Update. I am happy to say that I discovered last night that I have sago pondweed growing in my pond up to about one foot tall now. The only negative I have to report is that Mr. Cody had a good idea in that I should have planted some by hand. It appears that the bag method I used does not get all the tubers buried deep enough to keep them anchored. I found about 12 to 15 plants floating along the pond edges, tubers still intact, healthy and growing, but not anchored in the bottom any more. I assume they will die this way. My guess is that since the plant itself floats some of them were not achored good enough and just floated up off the bottom. I noticed that even thougth the plant may be a foot tall there really is no root system yet. The plant grows out of the tuber but the only root is a single 2 to 3 inch spike going downward. This apparently is not enough to hold the plant anchored. I'm glad that of the several hundred I planted there were only a few floating free. I replanted these plants by hand and we'll see what happens. I'm looking forward to a very weedy duck/forage pond.
