Growing potatoes from cut potatoes is a popular gardening hack that has been around for centuries. But does it really work? In this article, we’ll delve into the world of potato cultivation and explore the possibilities of growing potatoes from cut potatoes.
Understanding Potato Anatomy
Before we dive into the process of growing potatoes from cut potatoes, it’s essential to understand the anatomy of a potato. A potato is a type of root vegetable that belongs to the Solanum tuberosum species. It’s a starchy tuber that grows underground, and its structure is made up of several key components:
- Eyes: These are the small buds on the surface of the potato that contain the meristematic tissue, which is responsible for producing new growth.
- Stem: This is the above-ground part of the potato plant that grows from the eyes.
- Roots: These are the underground structures that absorb water and nutrients from the soil.
- Tuber: This is the edible part of the potato that grows underground.
The Science Behind Growing Potatoes from Cut Potatoes
Growing potatoes from cut potatoes is possible because of the unique properties of the potato’s eyes. Each eye contains a small amount of meristematic tissue, which is capable of producing new growth. When a potato is cut, the eyes are exposed, and the meristematic tissue is activated, allowing the potato to produce new roots and stems.
However, not all cut potatoes are created equal. The success of growing potatoes from cut potatoes depends on several factors, including:
- The number of eyes: A cut potato with multiple eyes has a higher chance of producing new growth than one with only one or two eyes.
- The size of the cut potato: A larger cut potato has more stored energy and nutrients, which can support the growth of new roots and stems.
- The variety of potato: Some potato varieties are more suitable for growing from cut potatoes than others.
How to Grow Potatoes from Cut Potatoes
Growing potatoes from cut potatoes is a relatively simple process that requires some basic gardening skills and equipment. Here’s a step-by-step guide to get you started:
Materials Needed
- Cut potatoes with at least one eye each
- Seed starting mix or potting soil
- Containers or seed trays
- Water
- A warm and sunny location
Step 1: Prepare the Cut Potatoes
- Choose healthy cut potatoes with at least one eye each.
- Allow the cut potatoes to dry for a few hours to form a callus over the cut surface. This will help prevent rot and disease.
- Cut the potatoes into sections, making sure each section has at least one eye.
Step 2: Plant the Cut Potatoes
- Fill the containers or seed trays with seed starting mix or potting soil.
- Plant the cut potato sections about 2-3 inches deep, with the eyes facing upwards.
- Water the soil gently but thoroughly.
Step 3: Provide the Right Conditions
- Place the containers or seed trays in a warm and sunny location, such as a greenhouse or a south-facing windowsill.
- Maintain a consistent temperature of around 70-80°F (21-27°C).
- Keep the soil consistently moist but not waterlogged.
Step 4: Monitor and Maintain
- Monitor the cut potatoes for signs of growth, such as sprouts or roots.
- Maintain the soil moisture and temperature levels.
- Fertilize the plants with a balanced fertilizer once they reach about 6 inches tall.
Challenges and Considerations
While growing potatoes from cut potatoes can be a fun and rewarding experience, there are some challenges and considerations to keep in mind:
- Disease and pests: Cut potatoes are more susceptible to disease and pests than whole potatoes.
- Low yields: Growing potatoes from cut potatoes can result in lower yields than growing from whole potatoes.
- Variable results: The success of growing potatoes from cut potatoes can vary depending on the factors mentioned earlier.
Tips and Variations
- Use certified disease-free potatoes: This can help reduce the risk of disease and pests.
- Try different varieties: Some potato varieties are more suitable for growing from cut potatoes than others.
- Experiment with different growing conditions: Try growing potatoes from cut potatoes in different locations, such as outdoors or in a cold frame.
Conclusion
Growing potatoes from cut potatoes is a fun and rewarding experience that can be a great way to produce your own food at home. While there are some challenges and considerations to keep in mind, with the right techniques and conditions, you can successfully grow potatoes from cut potatoes.

Can I grow potatoes from any cut potato?
You can grow potatoes from a cut potato, but not all cut potatoes are suitable for planting. The cut potato should have at least one “eye” each, and it’s best to use a certified disease-free seed potato. Regular potatoes from the grocery store may not produce well or may be more susceptible to disease.
When selecting a cut potato for planting, choose one that is firm and has a few eyes. Avoid using potatoes that are soft, rotten, or have green skin, as these can be toxic and may not produce a healthy crop. It’s also important to note that potatoes grown from cut potatoes may not produce tubers that are true to the variety of the parent potato.
How do I prepare a cut potato for planting?
To prepare a cut potato for planting, start by cutting the potato into sections, making sure each section has at least one eye. Let the cut sections dry for a day or two to form a callus over the cut area. This will help prevent rot and disease when the potato is planted.
Once the cut sections have dried, they are ready to plant. Plant the sections 2-4 inches deep in well-draining soil, with the eye facing upwards. Space the sections 12 inches apart, and water well. Keep the soil consistently moist during the first few weeks after planting.
What is the best time to plant cut potatoes?
The best time to plant cut potatoes depends on your location and climate. In general, it’s best to plant potatoes in early spring, about 2-4 weeks before the last frost date. This allows the potatoes to mature before the hot summer weather.
In areas with a long growing season, you can also plant potatoes in late summer or early fall, about 10 weeks before the first frost date. Avoid planting potatoes in the middle of the summer, as the heat can cause the tubers to rot.
How long does it take to grow potatoes from a cut potato?
The time it takes to grow potatoes from a cut potato can vary depending on the variety, weather, and growing conditions. On average, it takes about 70-100 days from planting to harvest. You can start checking for tubers about 7-10 weeks after planting, when the plants start to yellow and die back.
New potatoes, which are harvested before they reach full maturity, can be ready in as little as 50-60 days. Maincrop potatoes, which are allowed to mature fully, can take up to 120 days or more to be ready.
What are the benefits of growing potatoes from cut potatoes?
Growing potatoes from cut potatoes can be a fun and rewarding experience, and it has several benefits. One of the main advantages is that it allows you to grow potatoes from a small amount of seed material, making it a great option for small gardens or containers.
Another benefit is that growing potatoes from cut potatoes can help you save money on seed potatoes. You can also use this method to propagate your favorite potato varieties, and to experiment with new and unusual varieties.
What are the challenges of growing potatoes from cut potatoes?
One of the main challenges of growing potatoes from cut potatoes is the risk of disease. Cut potatoes can be more susceptible to disease, especially if they are not properly dried and cared for. Another challenge is the variability of the crop, as potatoes grown from cut potatoes may not produce tubers that are true to the variety of the parent potato.
To overcome these challenges, it’s essential to use certified disease-free seed potatoes, and to follow proper planting and care techniques. This includes providing the potatoes with well-draining soil, adequate moisture, and full sun.
Can I grow potatoes from cut potatoes in containers?
Yes, you can grow potatoes from cut potatoes in containers. In fact, containers can be a great option for growing potatoes, as they allow you to control the soil quality and moisture levels. To grow potatoes in containers, choose a container that is at least 6-8 inches deep, and fill it with a well-draining potting mix.
Plant the cut potato sections 2-4 inches deep, and water well. Keep the soil consistently moist, and provide the potatoes with full sun. You can also use a potato bag or a grow bag, which are specifically designed for growing potatoes.
