A humble fruit may be the secret to solving one of the most common kitchen frustrations. According to both traditional wisdom and modern science, placing an apple in your potato basket can keep your potatoes from sprouting too early. This method is simple, natural and surprisingly effective for anyone looking to reduce food waste and extend the shelf life of their pantry staples.
Why Potatoes Sprout Faster Than You Think
Potatoes are more sensitive than they look. Although they can survive for weeks without refrigeration, they are biologically programmed to grow. When stored in the wrong conditions, they respond by developing shoots. Light exposure, excess warmth and poor ventilation all signal the tuber to wake up and start the next cycle of growth.
This process may seem harmless at first, but sprouting also triggers chemical changes. One of them is the production of solanine, a bitter compound that the plant uses to protect itself from pests. A small amount is not dangerous, but when a potato becomes green or heavily sprouted, solanine levels can increase to the point where the flavor turns unpleasant and the potato may become unsuitable for eating.
Sprouting also means the potato is losing nutrients and moisture. Its texture becomes softer and the taste deteriorates. In other words, even before it looks bad, a sprouting potato is already past its prime.

Why Potatoes Sprout Slower When Stored Near Apples
The trick is simple. Place a single apple in your basket or container of potatoes and let the natural chemistry do the rest. Apples release a gas called ethylene, which plays a key role in plant development and ripening. While ethylene normally accelerates ripening in many fruits, it has the opposite effect on potatoes.
When present in low concentrations, ethylene inhibits cell elongation inside the potato. This slows down the internal processes that lead to sprout formation. As a result, potatoes stored with one apple can stay firm and sprout-free for several additional weeks.
This technique works best when the potatoes are already stored in proper conditions. A cool and dark location is essential to prevent light from triggering chlorophyll and solanine production. The presence of an apple adds an extra layer of control that delays natural degradation.
The Biggest Storage Mistake Most People Still Make
Storing potatoes near onions is a common but harmful habit in many kitchens. Onions release both ethylene and moisture, which together speed up sprouting and decay in potatoes. Keeping the two in the same container creates ideal conditions for spoilage, while apples, by contrast, emit low levels of ethylene that actually help slow sprouting.
Other frequent mistakes include refrigerating potatoes, which causes starch to turn into sugar and alters both taste and color when cooked. This can lead to the formation of acrylamide, a potentially harmful substance. Washing potatoes before storage also increases the risk of mold due to excess moisture. For best results, potatoes should be stored unwashed in a breathable basket or paper bag to allow airflow and maintain ideal humidity.
