When it comes to growing your own potatoes, one of the most common questions that gardeners ask is whether they can use shop bought potatoes to plant. The answer to this question is not a simple yes or no, as it depends on several factors. In this article, we will delve into the world of potato cultivation and explore the possibilities and limitations of using shop bought potatoes for planting.
Understanding Potato Varieties
Before we dive into the specifics of using shop bought potatoes, it’s essential to understand the different types of potato varieties available. Potatoes are classified into several categories, including first early, second early, maincrop, and late maincrop. Each variety has its unique characteristics, such as maturity period, yield, and disease resistance. First early potatoes are ready to harvest within 10-12 weeks, while maincrop potatoes take around 16-20 weeks to mature.
Potato Certification and Disease Resistance
Potatoes that are sold in shops are often certified disease-free and have been treated with chemicals to prevent sprouting. However, this certification does not guarantee that the potatoes are suitable for planting. In fact, many shop bought potatoes are treated with a sprout inhibitor to prevent them from growing eyes, which can reduce their shelf life. This treatment can make it difficult for the potatoes to grow when planted.
Potato Seed vs. Shop Bought Potatoes
It’s crucial to differentiate between potato seed and shop bought potatoes. Potato seed is specifically designed for planting and is certified to be disease-free and of high quality. These seeds are usually smaller and more expensive than shop bought potatoes but offer better yields and disease resistance. On the other hand, shop bought potatoes are intended for consumption and may not be suitable for planting.
The Risks of Using Shop Bought Potatoes
While it’s technically possible to use shop bought potatoes for planting, there are several risks involved. Disease transmission is a significant concern, as shop bought potatoes may carry diseases such as potato blight, scab, or powdery scab. These diseases can spread quickly and affect the entire crop, leading to reduced yields and poor quality tubers.
Potato Blight and Other Diseases
Potato blight is a devastating disease that can destroy an entire crop in a matter of days. It’s caused by the fungus Phytophthora infestans and can be spread through infected tubers, water, or air. Other diseases such as scab and powdery scab can also affect potato crops, causing reduced yields and poor quality tubers.
Reduced Yields and Poor Quality Tubers
Using shop bought potatoes for planting can also result in reduced yields and poor quality tubers. This is because shop bought potatoes are often older and of lower quality than potato seed, which can lead to reduced vigor and productivity. Additionally, shop bought potatoes may not be suitable for the local climate, which can further reduce yields and quality.

If you still want to use shop bought potatoes for planting, there are a few things you can do to increase the chances of success. First, choose potatoes that are high quality and disease-free. Look for potatoes with no signs of sprouting or rot and that are firm and smooth. You can also try to chit the potatoes before planting, which involves allowing them to sprout indoors before planting outside.
Chitting Potatoes
Chitting potatoes involves placing them with the eyes facing upwards in a light, cool place. This allows the potatoes to sprout and develop short, green shoots. Chitting can help to increase yields and reduce the risk of disease, as it allows the potatoes to develop a strong, healthy root system before planting.
Planting Shop Bought Potatoes
When planting shop bought potatoes, make sure to follow proper planting techniques. Plant the potatoes in well-draining soil with a pH between 4.5 and 7.0. Space the potatoes 12-18 inches apart and cover them with a layer of soil. Water the soil gently but thoroughly, and keep the soil consistently moist during the growing season.
Conclusion
While it’s possible to use shop bought potatoes for planting, it’s essential to be aware of the risks involved. Disease transmission, reduced yields, and poor quality tubers are all potential drawbacks of using shop bought potatoes. However, by choosing high-quality potatoes, chitting them before planting, and following proper planting techniques, you can increase the chances of success. For best results, it’s still recommended to use certified potato seed, which is specifically designed for planting and offers better yields and disease resistance.

Can I Use Shop Bought Potatoes to Plant?
Using shop-bought potatoes to plant can be a bit tricky. While it’s technically possible, there are some factors to consider before doing so. Shop-bought potatoes are often treated with chemicals to prevent them from sprouting, which can affect their ability to grow when planted. Additionally, these potatoes may be varieties that are not suitable for your local climate or soil type, which can impact their growth and yield. It’s essential to choose potatoes that are certified disease-free and suitable for your region to ensure the best results.
If you still want to use shop-bought potatoes, make sure to select ones that are high-quality and have at least one “eye” each. The “eye” is the small bud on the potato from which the new plant will grow. You should also check the potatoes for any signs of damage or rot, as these can spread disease to the new plants. It’s also crucial to note that using shop-bought potatoes may not produce the same results as using seed potatoes specifically designed for planting. Seed potatoes are bred to produce high yields and are often disease-resistant, making them a better choice for gardeners.
What is the Difference Between Shop Bought Potatoes and Seed Potatoes?
The primary difference between shop-bought potatoes and seed potatoes is their purpose and treatment. Shop-bought potatoes are grown for consumption and are often treated with chemicals to extend their shelf life and prevent sprouting. Seed potatoes, on the other hand, are specifically grown for planting and are certified disease-free. They are also bred to produce high yields and are often resistant to common potato diseases. Seed potatoes are typically smaller than shop-bought potatoes and have at least one “eye” each, which is essential for sprouting.
Using seed potatoes can significantly improve the chances of a successful harvest. They are designed to produce high yields and are less likely to be affected by diseases. Seed potatoes are also more likely to produce tubers that are true to type, meaning they will have the same characteristics as the parent plant. In contrast, shop-bought potatoes may produce tubers that are different from the parent plant, which can result in unpredictable yields and quality. For gardeners who want to grow high-quality potatoes, using seed potatoes is the best option.
How Do I Choose the Right Potatoes for Planting?
