I see nothing wrong with your potatoes.
You really don't need seed potatoes. That's a big scam.
All you need is a ten pound bag of potatoes from the store and to let them sit out for about a month and they'll do the same thing.
So everywhere there's an eye on a potato, cut a chunk of the potato "meat" off around the eye. Don't just pick the eye off. It needs to be attached to a small piece of the original potato so it thinks it's still alive.
Bury the eyes/cut off chunks, and eat the rest of the potato.
PS It's smarter to grow potatoes layered in 5 gallon buckets. Put some dirt in then a layer of potato cuttings.
Another layer, more potato cuttings.
And throughout the season, as you buy and eat more potatoes and cut off the eyes and a little flesh too, you just bury another layer of potato eyes.
At the end of the season, Flip over all your buckets o' potatoes onto the ground, and pick out all the big fat fatties. All the potatoes that are tiny, just throw those back in the buckets with the soil. And next time around they'll be ready.
And like I said, as you eat more papas, stick the eyes in the dirt filled buckets.
You can even sing a song to the tune of "Neverending Story". It goes "Neverending Pa-pas aaaaaaaaaaaaaaa"
Neverending, cyclical food and agriculture, potatoes rule.
PS grape hyacinth is another really easy crop. They are a bulb flower that wildlife usually doesn't see as food. The bulbs are edible when cooked and they taste like oniony potatoes. Takes a year to grow though, but they double every year, so you get twice the amount as last year.
PS x2 Sunchokes grow like crazy. Plant just a few sunchoke bulbs and within a few months you'll be digging up a ridiculous amount of sunchokes. Plus it's neat cos they have great big tall sunflower like blossoms that come up to pollinate.
Sunchokes are historic native american food.
