Yes! You can plant a sprouted potato and grow more potatoes. You will actually get several potato plants and ultimately a bunch of new potatoes from just one sprouted potato if you do it right.
First, prep your garden bed by mounding soil into rows
You’ll want to plant your potato sprouts within 2-3 days of preparing them so it’s best to get your garden bed ready to go, first.
Plant your sprouts.
Potato sprouts should be planted cut-side down, sprout-side facing up at least 12" apart. You’ll want to plant each sprout 3-4″ below the surface of the soil.
WATER AND FERTILIZE
Continue to water and weed around your potato plants.
Fertilize your soil if its not very rich. In general, potatoes need about 3 months to grow and produce a harvest.
Harvest your potatoes
You’ll know that your potato plants are ready to be harvested when the visible plant dies off either after the first frost or on its own, usually in the fall.
