1) It's hard to store potatoes until the spring, without either eating them all

2) Potatoes that are left behind in the garden accidentally will readily volunteer the next season and produce good plants.
There's always so much garden work in the spring, and so it would be great to be able to plant potatoes in the fall when I have more time. I experimented with this last year by cutting up potatoes and planting them in the fall. I definitely got potatoes, but I didn't pay enough attention to notice if my yields were lower.
It seems like planting cut potatoes in the fall would increase the potential for them to rot over the winter, so this year I might try to plant some smaller potatoes whole (although I don't know if planting smaller potatoes will select for small potato genes/traits). I live in Michigan, and my first frost will come any day now. We have snow on the ground from December-April, so the soil doesn't freeze during the winter. I would typically plant potatoes in May or June.
I'd love people's thoughts on this.
