A couple of potato questions: It used to be that I could find a nice variety of seed potatoes in local nurseries and sometimes feedstores. Yellow Finn, Yukon Gold, to name a couple. But, the last couple of years they've been hard to come by in that manner (I live in western Washington). When I was looking for them last year (when I still lived in southwest Washington), I found only one place that carried them and they had to travel quite a distance to find them and they weren't even in very good shape. I know you can order from the seed companies and I have a catalog from a company that just sells potatoes, but I don't want that many but I will order by mail if I have to. My question is: years ago I remember hearing that you should not use your grocery-store russets as seed potatoes but I can't remember the reason why. Something about them being treated with something maybe? Anyway, just curious. If anyone uses grocery-store potatoes with good results or know why I shouldn't, please let me know.
