bz, your method of planting the sago tubers is a good one. My sago in my small pond arrived naturally. I would have planted some of the tubers by hand (sticking them in the mud at 12"-16" deep), in the bags method, and by rubber-banding a small nail to each tuber and dropping it in desired areas. All methods would get the job done.
I have not seen any scuds since I planted them. I did save out about 2 dozen scuds from the shipment and put them in two buckets with coontail. I still have the scuds alive in the buckets plus there are a few young scuds in one of the buckets.
