Here’s what causes potatoes to sprout, whether they’re safe to eat, and how to keep them fresh for longer.
Why Do Potatoes Sprout?
Potatoes are living plant structures, which means they naturally try to grow when conditions are favorable.
Sprouting usually occurs when potatoes are exposed to:
Light
Warm temperatures
Humidity
Ethylene gas from nearby produce, especially onions
If your potatoes are sitting on the kitchen counter, near a sunny window, or stored alongside onions, they’re more likely to develop sprouts.
Many people assume refrigeration will solve the problem, but surprisingly, storing potatoes in the refrigerator is not recommended.
Cold temperatures can convert some of the potato’s starch into sugar, affecting both flavor and texture when cooked.
