Anticipate not unearthing potatoes until the emergence of this specific sign - instead, endure a 14-day period: Ancestral approach for preventing sprouting in the cellar, as shared by a grandfather
The optimal time to harvest potatoes is a crucial aspect for any potato grower. This method, based on the yellowing and dying back of the potato plant's foliage, ensures that the tubers are mature and ready for digging up[1][3][4].
When a potato plant matures, its foliage starts to lean to the sides, and the leaves turn yellow[2]. As the stems dry out and turn brown, it confirms that the plants are senescing, signalling that the tubers have matured[1][3].
Harvesting potatoes after this stage helps avoid issues like tuber rot or pest damage due to over-maturity in the ground[1][3]. For new potatoes (young, thin-skinned), digging can be done earlier, about 2–3 weeks before full foliage dieback[4].
Key points to remember when judging harvest time by foliage state:
- The yellowing of leaves signals tuber maturation.
- Drying and browning of stems confirm the plants are senescing.
- Careful digging, ideally in the morning when soil is cooler, helps prevent damage to the tubers[1].
- Handling tubers gently after harvest is also essential to maintain their quality[1].
Potatoes, the fourth most important food crop in the world, after rice, wheat, and corn, were domesticated in the Andes thousands of years ago and now number over four thousand varieties[5]. Harvesting potatoes at the specified time results in a tougher skin, improving storage and resistance to damage[6].
This method allows the tubers to reach their maximum size, ensuring a bountiful harvest for gardeners[7]. By following these guidelines, you can enjoy fresh, nutrient-rich potatoes while minimising waste and maximising your crop yield.

- Embracing a lifestyle centered around gardening, one might take note of their potato plants as they senesce, with yellow leaves and browning stems, signaling that it's time for food-and-drink enthusiasts to harvest the mature tubers.
- After the potato plants have reached maturity, as signified by the yellowing of leaves and browning of stems, gardeners can reap the benefits by venturing into the home-and-garden, gentlydigging up the tubers for a fresh food-and-drink experience, while ensuring that proper care is taken to maintain their quality.
