Harvesting Time: Differentiating Between New And Full-Sized Potatoes
Once potatoes have sprouted and started their growth journey, it is essential to understand the difference in harvesting timings between new and full-sized potatoes.
New potatoes refer to the small, immature tubers that are harvested for consumption at an earlier stage of growth. These early potatoes can be harvested approximately 10 weeks after planting, providing a tender and flavorful addition to meals.
On the other hand, full-sized potatoes, which are intended for storage, require a longer growing period. The time it takes for full-sized potatoes to mature can vary between 90 to 120 days. The duration depends on the potato type, climate, and specific variety being cultivated. Early season potatoes generally take around 90 days to reach maturity, with certain varieties maturing in as little as 75 days. Mid-season potatoes typically require approximately 100 days to reach full maturity. Late season potatoes, suitable for winter storage, have the longest maturation period, taking around 120 days.
The optimal time to start harvesting new potatoes is around two weeks after the plants begin to flower. At this stage, the potatoes are still small and have thin skins, providing a delicate texture and unique flavor.
On the other hand, mature potatoes should be harvested about two weeks after the leaves turn brown and the plants start to die back. This period allows for the nutrients in the plant to fully transfer to the tubers, ensuring their longevity during storage.
Potato Types And Their Maturity Periods
Potatoes can be categorized into three types based on their maturation periods: early, mid, and late-season potatoes. Each type has a different growth timeline, allowing for a diverse range of harvest times and culinary possibilities.
Early-season potatoes are those that require the shortest maturation period. These potatoes can be ready for harvesting in approximately 90 days, with some varieties maturing even earlier, in around 75 days. Their quick growth makes them an excellent choice for gardeners with a short growing season. Early-season potatoes are often prized for their tender and delicate texture.
Mid-season potatoes fall between the early and late season categories, taking approximately 100 days to reach their full maturity. This type of potato offers a balanced flavor and texture, making them suitable for a wide variety of culinary applications.
Late-season potatoes are typically harvested around 120 days after planting. These potatoes are known for their excellent storing capabilities, making them ideal for winter storage. With a longer growth period, late-season potatoes develop a denser texture and richer flavor, making them perfect for hearty winter dishes.
Harvesting And Curing Techniques For Potatoes
Harvesting and curing techniques have a significant impact on the quality and shelf life of potatoes. When it comes to harvesting, timing is crucial to maintain the flavor and texture of the potatoes.
New potatoes should be harvested for immediate consumption approximately two weeks after the plants start to flower. During this stage, they have a delicate skin and a tender texture. In contrast, mature potatoes, which are intended for storage, should be harvested around two weeks after the leaves turn brown and the plants begin to die back. This timing allows the potatoes to receive the necessary nutrients from the plant, ensuring their optimal quality for storage.
After harvesting, it is essential to cure the potatoes before storing them. Curing involves leaving the potatoes outdoors or in a covered area with proper air circulation for a few days. This process helps the potatoes develop a thicker skin, which enhances their longevity during storage. The duration of the curing period can vary up to two weeks, depending on the weather conditions and the specific potato variety.
