Maybe the easiest thing to grow. Get some seed taters, cut them into pieces, like quarter them or so depending on how good the eyes are...let them dry in a burlap bag for a couple days and plant them deep enough to get them covered over. Don't plant in mud or just before a long rainy period and I believe it helps to plant them on a good day according to the almanac. After the come up, I till alongside the row and pull dirt to them on each side to make a hill. Pull dirt to taters and away from onions.
What happens when you replant store bought potatoes? I see them growing the green stuff out if I don't eat them fast enough. Will those stalks turn into potatoes?
I have heavy clay soil that doesn't drain, I don't dig deep, but layer straw then seed spuds, but more straw then layers of dirt then straw.
Just planted sweet potatoes for the first time this year in late May, they seem to be taking off well in our soil. They grow on a vine though, which I thought was odd
That works well in soil with poor structure, what you are doing is basically adding soil organic matter which adds nutrients and improves soil tilth. I've seen potatoes grown in half barrels with nothing but straw as the medium. The "green stuff" that grows off of potatoes are sprouts.
Right, I just lop up the sprouting potatoes as my seed stock. The other advantage of 'the pile' is harvesting. Digging out undersized stops out of clay is hard work for little benefit, the layers of straw hold moisture and allow larger potatoes... everything gets tilled in later. My old garden has now become a small food plot for the backyard deer. Here is the old garden with a weeks growth. Its bordered by some peach trees, which they are cleaning up the drops. This one is looking like she will drop soon.
