The potatoes are also growing lushly and are blooming but since I ran out of dirt to keep piling up around the plants early on I don't know how many potatoes I'm going to get. I don't even know when I'm supposed to harvest them. When the plants die down I guess. Now that they are blooming, it is too late to pile up more dirt?
So I cut off the dead part and watered it well and crossing my fingers that it still has several more good sized roots.
