Growing your own potatoes can be a rewarding and delicious experience, but before you start, you might wonder if you can use supermarket potatoes as seed potatoes. The answer is not a simple yes or no, as it depends on several factors, including the type of potato, its treatment, and your location. In this article, we will delve into the world of potato cultivation, exploring the possibilities and challenges of growing potatoes from supermarket potatoes.
Understanding Potato Types and Treatments
To determine if you can grow potatoes from supermarket potatoes, it’s essential to understand the different types of potatoes and how they are treated. Supermarket potatoes are often grown for their flavor, texture, and storage quality, rather than for their seed production. These potatoes may be treated with growth inhibitors to prevent them from sprouting during storage, which can affect their ability to produce new plants.
Potato Classification
Potatoes are classified into several categories, including:
First early, second early, maincrop, and late maincrop potatoes. Each type has its own unique characteristics, such as maturation period, yield, and disease resistance. First early potatoes, for example, are bred for their fast maturation and high yield, while maincrop potatoes are grown for their larger tubers and longer storage life.
Treatment of Supermarket Potatoes
Supermarket potatoes may undergo various treatments to extend their shelf life and prevent sprouting. These treatments can include:
Chemical treatment with chlorpropham (CIPC), a growth regulator that inhibits sprouting, and physical treatment, such as refrigeration or controlled atmosphere storage, to slow down the aging process. While these treatments help maintain the quality of supermarket potatoes, they can also reduce their ability to produce viable offspring.
Growing Potatoes from Supermarket Potatoes: Is it Possible?
While it’s technically possible to grow potatoes from supermarket potatoes, the success rate may vary depending on the factors mentioned earlier. Certified seed potatoes, on the other hand, are specifically grown for their seed production and are not treated with growth inhibitors. These seed potatoes are tested for diseases and pests, ensuring that they produce healthy and vigorous offspring.
Challenges of Growing Supermarket Potatoes
Growing potatoes from supermarket potatoes can pose several challenges, including:
Low germination rates, reduced yields, and increased risk of disease transmission. Supermarket potatoes may be more susceptible to diseases like potato scab, blackleg, or powdery scab, which can reduce yields and affect the quality of the tubers.
Overcoming the Challenges
To overcome the challenges of growing potatoes from supermarket potatoes, you can try the following:
Choose potatoes that are high in starch and have fewer eyes, as they tend to produce more tubers. You can also try to remove the growth inhibitors by letting the potatoes sprout before planting them. However, this method is not foolproof, and the results may vary.
Best Practices for Growing Potatoes
Whether you’re growing potatoes from supermarket potatoes or certified seed potatoes, following best practices can help ensure a successful harvest. Here are some tips to keep in mind:
- Choose a **sunny location** with well-draining soil and a pH between 4.5 and 7.0.
- **Prepare the soil** by adding organic matter like compost or manure to improve its structure and fertility.

- **Water and maintain** the soil consistently, keeping it moist but not waterlogged.
- **Monitor for pests and diseases**, taking action promptly if you notice any issues.
Conclusion
Growing potatoes from supermarket potatoes can be a fun and rewarding experience, but it’s essential to understand the challenges and limitations involved. By choosing the right type of potato, removing growth inhibitors, and following best practices, you can increase your chances of success. However, for a more reliable and disease-free harvest, certified seed potatoes remain the best option. Whether you’re a seasoned gardener or a beginner, growing your own potatoes can be a delightful experience, and with the right knowledge and techniques, you can enjoy a bountiful harvest of delicious, homegrown potatoes.
Can I Grow Potatoes from Supermarket Potatoes?
Growing potatoes from supermarket potatoes is technically possible, but it’s not the most recommended approach for several reasons. Supermarket potatoes are often treated with chemicals to inhibit sprouting, which can reduce their viability for planting. Additionally, these potatoes may be varieties that are not well-suited for your local climate or growing conditions, which could lead to disappointing results. However, if you still want to try, make sure to choose potatoes that are fresh and have at least one “eye” each, as these are the parts from which new plants will grow.
It’s also important to note that supermarket potatoes may be more prone to disease, as they are often grown using intensive farming practices that can lead to a higher risk of infection. This could not only affect the health of your potato crop but also potentially spread disease to other plants in your garden. If you do decide to use supermarket potatoes, be sure to inspect them carefully for any signs of damage or disease before planting, and consider treating them with a fungicide to reduce the risk of infection. It’s generally recommended to purchase seed potatoes from a reputable supplier, as these are specifically grown and certified for planting.
What are the Best Types of Potatoes for Home Growing?
The best types of potatoes for home growing depend on your personal preferences, climate, and the amount of space you have available. Some popular varieties for beginners include ‘Russet’, ‘Yukon Gold’, and ‘Red Bliss’, as these are relatively easy to grow and produce high yields. If you’re looking for a more exotic variety, you might consider ‘Purple Peruvian’ or ‘Butte’, which offer unique flavors and textures. It’s also a good idea to choose varieties that are resistant to common potato diseases, such as late blight or scab, to reduce the risk of infection.
When selecting a potato variety, consider factors such as maturity date, yield potential, and disease resistance. You may also want to think about the intended use of your potatoes – for example, if you want to grow potatoes for boiling or roasting, you may prefer a variety with a waxy texture, such as ‘Red Thumb’ or ‘Fingerling’. On the other hand, if you’re looking to grow potatoes for mashing or baking, a variety with a higher starch content, such as ‘Russet’ or ‘Idaho’, may be a better choice. By selecting the right variety for your needs and growing conditions, you can enjoy a successful and rewarding potato harvest.
How Do I Prepare Supermarket Potatoes for Planting?
To prepare supermarket potatoes for planting, start by allowing them to sprout for a few weeks before planting. You can do this by placing the potatoes in a light, cool place, such as a sunny windowsill or a cold frame. Once the sprouts have grown to about 1-2 inches long, you can cut the potatoes into sections, making sure each section has at least one “eye”. Allow the cut sections to dry for a day or two to form a callus over the cut surface, which will help prevent rot and infection.
It’s also a good idea to treat the potato sections with a fungicide before planting, to reduce the risk of disease. You can purchase fungicides specifically designed for seed potatoes at most garden centers or online. Be sure to follow the instructions carefully and take any necessary precautions to avoid exposure. Once the potato sections are ready, you can plant them in well-draining soil with full sun, about 2-4 inches deep, and space them 12 inches apart. Water the soil gently but thoroughly after planting, and keep the soil consistently moist but not waterlogged.
What are the Chances of Success with Supermarket Potatoes?
The chances of success with supermarket potatoes are variable and depend on several factors, including the variety, growing conditions, and how well the potatoes are prepared for planting. As mentioned earlier, supermarket potatoes may be treated with chemicals to inhibit sprouting, which can reduce their viability for planting. Additionally, these potatoes may be more prone to disease, which can affect their growth and productivity. However, if you’re willing to take the risk and follow proper preparation and planting procedures, you may still be able to achieve a successful harvest.
On average, you can expect a lower success rate with supermarket potatoes compared to using certified seed potatoes. However, with proper care and attention, it’s still possible to achieve a decent yield. To maximize your chances of success, make sure to choose fresh, healthy-looking potatoes, and follow proper preparation and planting procedures. It’s also essential to provide your potatoes with optimal growing conditions, including full sun, well-draining soil, and consistent moisture. By taking these steps, you can increase your chances of a successful harvest, even with supermarket potatoes.
Can I Save My Own Potato Seeds for Next Year’s Crop?
Saving your own potato seeds for next year’s crop is technically possible, but it’s not the most recommended approach. Potatoes are typically propagated using tubers, rather than true seeds, as this allows growers to preserve the desirable traits of the parent plant. However, if you do want to save your own potato seeds, you’ll need to allow some of your potato plants to produce flowers and seeds, which can be a time-consuming and labor-intensive process. You’ll also need to ensure that the seeds are properly harvested, dried, and stored to maintain their viability.
It’s generally recommended to purchase certified seed potatoes each year, rather than trying to save your own seeds. This is because seed potatoes are specifically grown and certified to be disease-free and true to type, which helps ensure a healthy and productive crop. Additionally, using certified seed potatoes can help reduce the risk of disease and pests, which can be devastating to a potato crop. If you do decide to save your own potato seeds, make sure to follow proper procedures for harvesting, drying, and storing the seeds, and be prepared for potential variations in the resulting crop.
How Long Does it Take to Grow Potatoes from Supermarket Potatoes?
The time it takes to grow potatoes from supermarket potatoes can vary depending on factors such as the variety, growing conditions, and weather. On average, it can take anywhere from 70 to 100 days or more to mature, from the time the potatoes are planted. This is because supermarket potatoes may not be as vigorous or healthy as certified seed potatoes, which can affect their growth rate and productivity. Additionally, the potatoes may need to be started indoors or in a cold frame before being transplanted outside, which can add to the overall growing time.
To ensure the best possible results, make sure to provide your potatoes with optimal growing conditions, including full sun, well-draining soil, and consistent moisture. You can also consider using a technique called “chitting”, which involves allowing the potatoes to sprout indoors before planting, to give them a head start on the growing season. By following proper growing procedures and providing your potatoes with the right conditions, you can enjoy a successful and rewarding harvest, even with supermarket potatoes. Just be patient and flexible, as the growing time may be longer than expected.
