Did You Know?
1. The ancient Incas were the first to cultivate and cut seed potatoes, using a method known as “chuño.” They would freeze the potatoes overnight, then stomp on them with their feet to remove the water content, resulting in freeze-dried potatoes that could be stored for several years.
2. The process of cutting seed potatoes originated in the 18th century in Ireland, during a time of extreme food shortage. By cutting the larger potatoes into small pieces, farmers could plant more crops and maximize their yield, thus mitigating the effects of the famine.
3. Did you know that cutting seed potatoes is not always necessary? Some varieties, such as the “True Potato Seed” varieties, produce seeds instead of tubers. These seeds can be directly sown into the ground for potato cultivation, eliminating the need for cutting.
4. In the 1940s, during World War II, British farmers were limited to a certain amount of seed potatoes due to rationing. To cope with this restriction, they started practicing a technique called “chitting,” which involves placing whole potatoes in shallow trays and exposing them to light, encouraging sprouting. By doing so, one potato could produce multiple seed pieces for planting.
5. When cutting seed potatoes, it is crucial to use a clean and sharp knife or tool. This not only ensures a cleaner cut but also minimizes the risk of transferring soil-borne pathogens and diseases to the freshly cut potatoes, thus safeguarding the overall crop health.
Benefits Of Cutting Seed Potatoes
Cutting seed potatoes before planting is a technique that can greatly benefit gardeners by saving seeds and producing more plants in the garden. By cutting seed potatoes, gardeners have the ability to double the number of seeds and increase the harvest in the fall. This method allows for the propagation of multiple plants from a single seed potato, maximizing the yield and efficiency of potato cultivation.
Moreover, cutting seed potatoes not only saves seeds but also improves the overall growth and productivity of potato plants. Each seed potato contains many “eyes,” which are the sprouts that will become the potato plant. Each plant only needs 3 or 4 sprouts to establish and be productive. By cutting the seed potatoes into smaller pieces, each with its own sprouts, the plant has a better chance of success. This method allows for the selection of the healthiest and most robust sprouts, resulting in stronger and more productive plants.

Some gardeners cut the seed potatoes into smaller pieces with only 2 eyes, but larger pieces with more eyes give the plant a better chance of success.
Each piece should be at least 2 or 3 inches long and wide. This size provides enough space for the sprouts to grow and ensures that the potato plant will have sufficient nutrients and energy for its development.
To summarize:
- Gather the necessary tools, including a sharp knife
- Avoid cutting through any of the eyes
- Divide the seed potato into 2 or 3 pieces, ensuring each piece has at least 4 eyes
- Each piece should be at least 2 or 3 inches long and wide
By following these guidelines, gardeners can effectively cut seed potatoes and set them up for optimal growth.
Factors To Consider Before Cutting Seed Potatoes
Although cutting seed potatoes can be beneficial, there are a few factors that gardeners need to consider before proceeding with this technique. Cutting seed potatoes is not advised if there are soil-borne viral or bacterial diseases affecting plants in the Solanaceae family. These diseases can easily spread through the cut surfaces and affect the entire plant, leading to a significant decrease in yield.
Additionally, if there have been potato disease problems in the garden, it is recommended to skip cutting seed potatoes. By avoiding the cutting process, gardeners reduce the risk of transferring any potential disease to healthy plants. It is important to prioritize the health and well-being of the entire crop to ensure a successful harvest.
Preparing Cut Seed Potatoes For Planting
After cutting the seed potatoes, properly preparing them for planting is crucial. Here are the steps to follow:
-
Cure the cut potatoes: Leave them for a few days in an airy, dry place out of the sun. This process allows the cut surfaces to dry and form a protective layer, reducing the risk of rot and disease.
-
Planting the cut seed potatoes: Place them with the cut side down and the eyes facing up. This positioning ensures that the sprouts have easy access to the soil and can establish roots quickly.
-
Cover the cut seed potatoes: Add about 2 or 3 inches of soil to cover them. This provides the necessary support and protection for the growing potatoes.
-
Mound soil on the emerging greens: Throughout the growing season, it can be beneficial to mound soil on the emerging greens of the potato plants. This promotes healthy growth, increases tuber production, and helps prevent potatoes from becoming green or exposed to sunlight, which can cause them to turn bitter.
Remember to keep these guidelines in mind when preparing and planting cut seed potatoes. Proper curing, correct positioning, and soil mounding are key to successful potato growth.
- Curing the cut potatoes for a few days in an airy, dry place
- Planting with the cut side down and eyes facing up
- Covering with 2 or 3 inches of soil
- Mounding soil on the emerging greens throughout the growing season
Tips For Maximizing Yield With Cut Seed Potatoes
To maximize yield when using cut seed potatoes, follow these additional tips:
-
Pre-sprouting: Store seed potatoes in a cool, dark root cellar until two weeks before planting. This promotes sprout development and reduces the time to mature potatoes in the field by 10-14 days.
-
Warm the seed potatoes: Before planting, warm the potatoes at 70°F for 48-72 hours. This improves their germination rate and leads to increased yields.
-
Cutting larger potatoes: Larger potatoes should be cut into smaller pieces, with each piece having at least two sprouts. Small potatoes can be planted whole.
-
Minimize the risk of rot: Leave seed potatoes at room temperature for at least twenty-four hours before planting to reduce the chance of rot. Additionally, dusting the cut surfaces with calcitic or dolomitic agricultural lime or sulfur can help prevent rot.
Following these tips will ensure the successful growth and development of the potato plants.
Alternative Planting Methods For Seed Potatoes
While cutting seed potatoes is a popular and effective technique, there are alternative planting methods that gardeners can consider. One such method is the “Lazy Bed Potato Planting Method.” This method involves digging trenches or furrows in the ground and placing the seed potatoes directly in them, without cutting or curing them beforehand. The potatoes are then covered with soil and mounded as they grow.
Rotating the potato crop and using the lazy bed method can result in easy and productive potato growth. These alternative methods provide additional options for gardeners seeking different approaches to planting seed potatoes, allowing them to find the best method that suits their needs and preferences.

Frequently Asked Questions
How do you get seeds from a potato plant?
To obtain seeds from a potato plant, one must first allow the plant to flower and form berries. These berries, resembling miniature green tomatoes, typically bear around three hundred true potato seeds, though certain varieties yield fewer. Once the berries have matured, they can be carefully collected and the seeds extracted for propagation. This process guarantees a new generation of potato plants, allowing for diverse varieties and continued cultivation in various climates.
How do you get seed potatoes to sprout?
To encourage seed potatoes to sprout, it is necessary to create the right conditions for them. Start by selecting the desired varieties and arranging them in a shallow box with adequate space between each potato. Choose a spot under a south-facing window where the potatoes can receive ambient light without direct exposure. This careful placement is crucial as direct sunlight can lead to greening and the production of an undesirable toxin in the potatoes. By providing the potatoes with the ideal environment, sprouting will be stimulated, ensuring healthy and toxin-free growth.
What is the difference between seed potatoes and regular potatoes?
Seed potatoes are specifically meant for planting and growing new potato plants, while regular potatoes are typically used for consumption. The main distinction lies in the treatment of these potatoes. Regular potatoes found in grocery stores undergo a process where they are treated with sprout inhibitors to prevent the development of eyes during storage and on shelves. On the other hand, seed potatoes are never treated with these inhibitors, making them ideal for cultivating potatoes successfully as they are able to sprout and produce new plants. Consequently, using seed potatoes increases the chances of a successful potato harvest compared to using regular ones.
Do seed potatoes multiply?
Yes, seed potatoes have the ability to multiply. When potatoes are harvested, a portion of the crop is reserved for planting in the following season. These seed potatoes, when planted, develop into new potato plants, resulting in a multiplied yield of potatoes. This process of using seed potatoes allows for the renewal of the potato cycle, ensuring a continuous supply of this versatile crop.
