This is my first time growing potatoes, the seed potatoes I got at Walmart well past the planting season and they looked really bad, all dehydrated and shriveled up. My sister said "what have you got to loose", so I planted them. The plant had bloomed and died back, it had no leaves left, I knew it was time to dig even though, they were not in the grown long enough. I got lots of tiny little potatoes and few bigger ones. Next season I'm going to the experts, my local Co-Op for help.
