Most potatoes are not grown from seed, but rather by planting out “seed potatoes,” which are just high-quality whole potatoes, or pieces of potatoes, that were saved from a previous season. Here in Alabama, February is the best month to plant them, which is what Eric and the students did, despite all the rain. There are many ways to plant out potatoes, but at Rural Studio Farm the students set them out along shallow trenches in the newly built in-ground raised beds.
Then, students covered the potatoes with several inches of hay (many growers hill up soil around the seed potatoes). The hay protects the potatoes, modulates temperatures, suppresses weeds, and helps to retain moisture.
After a few weeks, the potatoes pushed their way through the hay and continued to grow.
Once the sprouts reached about 8 – 12 inches, Eric then hilled up even more hay around the plants until only the growing tips were left exposed. As the potatoes grow, the tubers will form in the hilled-up hay, increasing yields. This also eliminates the need to do any digging to harvest the potatoes—just open up the hay.
