"If you dig up one small piece of each that you want to keep and storethat, you can have as many as you want next year." Leo, is the number of sprouts from any one tuber determined by the number of growing points that are on the piece of attached stem, or can more than one sprout be produced even if there's only one growth point? Do the sprouts develop roots into the water (like a sweet potato slip), or are they rootless when you take them off to pot up? Thanks, Jonathan z8b/9a, Alachua/Gainesville, (North Central) Florida
