4. I find potatoes among the easiest things to grow.
My experiment of the last 4 years has been perennializing potatoes by leaving some behind in the bed, mulching deeply, and fertilizing well each year. Its worked out surprisingly well, except last summer voles moved in and started going after them, so not sure what will come up on the spring. I always had leftovers sprout here and there most years, so I thought, what the heck, why not try it. And it worked. No disease problems that I've noted.
