“The reason why potatoes sprout,” explains Jenny McNally, “is because if it’s warm, the potatoes can be tricked into thinking it’s spring. People tend to have their houses at a temperature of around 20 degrees, which is the ideal growing temperature for potatoes.”
Why do potatoes grow sprout?

How do potatoes reproduce naturally?
Unlike other major field crops, potatoes are reproduced vegetatively, from other potatoes. Therefore, a part of each year’s crop – from 5 to 15 percent, depending on the quality of the harvested tubers – is set aside for re-use in the next planting season.
What happens to the original potato you plant?
The sprouts then develop into independent plants. The cut potato piece or “seed” piece provides the new sprout or seedling with nourishment from its supply of stored starch. After you’ve planted a seed piece, it usually takes one to two weeks for the main stem and first leaves to appear above ground.

Why are sprouting potatoes poisonous?
Dear Bob: Potato sprouts are considered toxic due to their potentially high concentration of glycoalkaloids, which can exert their toxic effects on the nervous system by interfering with the body’s ability to regulate acetylcholine, a chemical responsible for conducting nerve impulses.
Why are potato eyes called eyes?
Each tuber or potato has several buds. These are the small sprouts we call potato “eyes.” It’s from these buds that new potato plants can grow. So even though a potato’s eyes can’t help it see underground, they can help grow more potatoes!
Is potato skin toxic?
Glycoalkaloids occur naturally in potatoes and are toxic to humans at high levels. Glycoalkaloids are concentrated in the peel and prolonged exposure of tubers to light will stimulate the formation of glycoalkaloids near the surface of the potato tuber.
Can dogs eat potatoes?
White potatoes belong to the nightshade family of vegetables, which includes tomatoes; like tomatoes, raw potatoes contain solanine, a compound that is toxic to some dogs. However, cooking a potato reduces the levels of solanine. If you do feed your dog a potato, it should be baked or boiled, with nothing added to it.
What to do with sprouting potatoes?
You can eat slightly sprouted potatoes as long as they feel firm and you remove the sprouts first. Just like green potato skin, potato sprouts contain solanine, a bitter compound that can make you sick.
Can potatoes grow without sunlight?
Although potato plant leaves need light to grow, their tubers and roots do not need light. In fact, potato tubers will turn green and produce a toxic substance (solanine) when exposed to light. Potato tubers turn green and produce the toxic substance solanine when exposed to sunlight for too long.
