Potatoes are one of the most versatile and widely consumed vegetables globally, and for many gardeners, the idea of growing their own potatoes from store-bought ones can be intriguing. The question often asked is, can you start potatoes from store bought potatoes? The answer is yes, but it requires careful consideration and preparation to ensure success. In this article, we will delve into the details of how to start potatoes from store-bought potatoes, discussing the benefits, challenges, and best practices for achieving a bountiful harvest.
Understanding the Basics of Potato Growth
Before diving into the specifics of starting potatoes from store-bought ones, it’s essential to understand the basics of potato growth. Potatoes are a cool-season crop that belongs to the Solanaceae family, which also includes tomatoes, peppers, and eggplants. They are propagated using seed potatoes or pieces of potatoes that contain at least one “eye” each. The eye is the part of the potato from which new growth emerges.
The Role of Eyes in Potato Growth
The eyes on a potato are not just for show; they play a crucial role in the growth and development of a new potato plant. Each eye has the potential to produce a new stem and roots, making them the key to successful potato propagation. When a potato is cut into pieces for planting, each piece must contain at least one eye to ensure that it can grow into a new plant.
Choosing the Right Store-Bought Potatoes
Not all store-bought potatoes are suitable for starting new plants. When selecting potatoes for this purpose, look for ones that are certified disease-free and have not been treated with sprout inhibitors. Many commercial potatoes are treated to prevent them from sprouting, which makes them unsuitable for starting new plants. Opt for organic or non-treated potatoes whenever possible.
Preparing Store-Bought Potatoes for Planting
Once you have selected the right store-bought potatoes, the next step is to prepare them for planting. This involves several key steps to ensure that your potatoes are ready to produce healthy and vigorous plants.
Curing and Sprouting
After buying your potatoes, it’s essential to let them cure for a few days to a week before preparing them for planting. Curing involves storing the potatoes in a cool, dark place with good ventilation to allow the skin to thicken and any wounds to heal. After the curing process, move the potatoes to a bright and cool location (around 60-70°F or 15-21°C) to encourage sprouting. This step is crucial as it helps to break dormancy and stimulates the eyes to produce new growth.
Cutting and Treating the Potatoes
Once your potatoes have sprouted, it’s time to cut them into pieces for planting. Each piece must contain at least one eye. To minimize the risk of rot and disease, allow the cut pieces to dry for a day or two before planting. This process, known as “healing,” helps to form a callus over the cut area, reducing the risk of infection.
Planting and Caring for Your Potato Crop
With your potatoes properly prepared, the next step is to plant them. The timing of planting depends on your climate, but in general, potatoes are planted in early spring or late summer/early fall to avoid the hottest part of the year.
Planting Depth and Spacing
Plant your potato pieces 2-4 inches deep, with the eyes facing upwards. The spacing between plants can vary depending on the variety, but a general rule of thumb is to plant them about 12 inches apart in rows that are 3 feet apart. This spacing allows for good air circulation, which is essential for preventing disease.
Post-Planting Care
After planting, your main tasks will be to keep the soil consistently moist and to hill the potatoes as they grow. Hilling involves mounding soil around the base of the plants to encourage tuber formation and prevent greening. Keep the area weed-free and monitor your plants for signs of pests or diseases, taking action promptly if you notice any issues.
Challenges and Considerations
Starting potatoes from store-bought ones can be rewarding, but it also comes with its challenges. One of the main considerations is the risk of disease. Since store-bought potatoes may not be certified disease-free, there’s a higher risk of introducing diseases into your garden. Furthermore, the variety of the potato may not be well-suited to your local climate, which can affect yield and disease resistance.
Genetic Diversity and Variety Selection
When starting potatoes from store-bought ones, you are limited to the varieties available in the supermarket. This can result in a lack of genetic diversity in your potato crop, making it more vulnerable to diseases. Consider obtaining seed potatoes from a reputable supplier for access to a wider range of varieties, including those that are resistant to common potato diseases.
Conclusion
Starting potatoes from store-bought potatoes can be a fun and rewarding experience, offering a glimpse into the cycle of growth and the possibility of enjoying a homegrown harvest. However, it requires careful planning, preparation, and attention to detail to overcome the potential challenges. By following the guidelines and best practices outlined in this article, you can successfully grow potatoes from store-bought ones and enjoy the satisfaction of nurturing your food from seed to table. Remember, the key to success lies in choosing the right potatoes, preparing them properly, and providing the right conditions for growth. Happy gardening!

Can I use any store-bought potato to grow new potatoes?
The answer is not exactly, as not all store-bought potatoes are suitable for growing new potatoes. Some potatoes are treated with growth inhibitors to prevent them from sprouting, which can significantly reduce the chances of successful growth. These potatoes are often labeled as “non-sprouting” or “treated,” and it’s best to avoid them for growing purposes. On the other hand, some store-bought potatoes may be certified disease-free or have been specifically grown for seed production, making them ideal for starting new potato plants.
To increase the chances of success, look for store-bought potatoes that are high in starch, such as Russet or Idaho potatoes, as they tend to produce more vigorous growth. Also, choose potatoes with at least one “eye” each, as these are the points from which new growth will emerge. It’s also essential to check the potatoes for any visible signs of disease or damage, as these can significantly impact the health and productivity of the resulting plants. By selecting the right type of potato and handling them properly, you can successfully grow new potatoes from store-bought ones.
How do I prepare store-bought potatoes for planting?
Preparing store-bought potatoes for planting involves a few simple steps to encourage sprouting and increase the chances of successful growth. Start by allowing the potatoes to “chit” or sprout, either by placing them in a light, cool place with the “eyes” facing upwards or by using a specialized chitting tray. This process can take anywhere from a few weeks to a few months, depending on the variety and conditions. As the potatoes sprout, you’ll notice small, green shoots emerging from the eyes, which will eventually develop into leaves and stems.
Once the potatoes have developed short, green shoots, it’s time to cut them into sections, making sure each section has at least one “eye” and a small amount of tuber attached. Allow the cut sections to dry for a day or two to form a callus over the cut area, which will help prevent rot and disease. This step is crucial, as it will help the potato sections to heal and reduce the risk of infection. After the sections have dried, they’re ready to be planted in a container or directly in the ground, following standard potato planting guidelines. With proper preparation, you can give your store-bought potatoes the best chance of developing into healthy, productive plants.
What is the best time to plant potatoes grown from store-bought potatoes?
The best time to plant potatoes grown from store-bought potatoes depends on your location and climate.
