Timing is crucial when it comes to harvesting potatoes for long-term storage. While young potatoes can be enjoyed as early as June, for winter storage, it’s best to wait until late summer or early autumn. The optimal harvest period typically falls in August and early September, depending on factors like variety, weather, and irrigation.
To ensure potatoes can survive winter, they must be fully ripe. Look for dry, sunny days for harvesting, as wet potatoes are prone to rot. A key sign of maturity is the state of the stem; if it begins to wither, the potatoes are ready. Additionally, extracting a few bushes can help: if the skin is thick and most tubers have separated from the roots, it’s time to harvest.
For harvesting, experienced gardeners recommend using a pitchfork instead of a shovel. Insert it about 15-20 centimeters from the base of the bush to gently lift the soil. Smooth the ground afterward to avoid leaving tubers behind. Separate any damaged potatoes for immediate use.
After harvesting, don’t rush to store the potatoes in boxes. Instead, lay them in a single layer on newspaper or cardboard in a cool, dark place (10-15 °C) with high humidity and good ventilation for 1-2 weeks. This method helps to strengthen the skin and extend storage life.
