Potatoes are one of the most widely consumed staple foods globally, and growing them can be a rewarding experience. However, when potatoes start growing roots, it can be a sign of improper storage or handling. In this article, we will explore the reasons behind root growth in potatoes, the risks associated with it, and provide a step-by-step guide on what to do when potatoes start growing roots.
Understanding Potato Root Growth
Potatoes are a type of root vegetable that grows underground. They have a unique characteristic called “dormancy,” which allows them to remain in a state of suspended animation for several months. During this period, potatoes can withstand cold temperatures, dry conditions, and even physical damage. However, when potatoes are exposed to favorable conditions such as warmth, moisture, and light, they can break dormancy and start growing roots.
Why Do Potatoes Grow Roots?
There are several reasons why potatoes start growing roots:
- Temperature fluctuations: Potatoes are sensitive to temperature changes. When stored at room temperature or exposed to warm conditions, potatoes can break dormancy and start growing roots.
- Moisture content: High humidity or excessive moisture can trigger root growth in potatoes.
- Light exposure: Potatoes can grow roots when exposed to light, especially if they are stored in a bright or sunny location.
- Physical damage: Damaged or bruised potatoes can start growing roots as a natural response to injury.
- Aging: As potatoes age, they can naturally break dormancy and start growing roots.
Risks Associated with Potato Root Growth
While root growth in potatoes may seem harmless, it can pose several risks:
- Reduced quality: Potatoes with roots can become soft, mushy, and unappetizing.
- Increased risk of rot: Root growth can create entry points for bacteria and fungi, leading to rot and decay.
- Decreased shelf life: Potatoes with roots can spoil faster than those without roots.
- Loss of nutritional value: Root growth can lead to a decrease in the nutritional value of potatoes.
What to Do When Potatoes Start Growing Roots
If you notice your potatoes starting to grow roots, follow these steps:
Step 1: Inspect the Potatoes
Carefully inspect the potatoes for any signs of rot, mold, or decay. Check for soft spots, slimy texture, or an off smell. If you notice any of these signs, it’s best to discard the potatoes.
Step 2: Remove the Roots
Gently remove the roots from the potatoes using a sharp knife or a vegetable peeler. Be careful not to damage the potato flesh.
Step 3: Dry the Potatoes
Dry the potatoes thoroughly with a clean towel or paper towels to remove excess moisture.
Step 4: Store the Potatoes Properly
Store the potatoes in a cool, dark place with good ventilation. The ideal storage conditions for potatoes are:
- Temperature: 40°F to 50°F (4°C to 10°C)
- Humidity: 80% to 90%
- Light: Dark or low light conditions
Step 5: Monitor the Potatoes
Regularly monitor the potatoes for any signs of further root growth or decay. If you notice any issues, remove the affected potatoes to prevent spoilage.

What are the signs that potatoes are ready to be harvested after they start growing roots?
When potatoes start growing roots, it’s essential to monitor their growth to determine the optimal time for harvesting. Some signs that indicate potatoes are ready to be harvested include the yellowing of the leaves, the stems beginning to fall over, and the skin of the tubers becoming set. You can also gently dig around the plants with your fingers to feel for the tubers. If they’re the desired size, it’s time to harvest.
Another way to check for readiness is to wait for about 70 to 100 days after planting, depending on the variety. Some potato varieties mature faster than others, so it’s crucial to check the specific days to maturity for your particular variety. Keep in mind that new potatoes, which are harvested before they reach full maturity, will be ready sooner than maincrop potatoes.
How do I prevent potatoes from growing roots too early or too late?
To prevent potatoes from growing roots too early, make sure the soil is cool enough before planting. Potatoes typically thrive in temperatures between 40°F and 70°F (4°C and 21°C). If the soil is too warm, the tubers may sprout too quickly, leading to weak and leggy growth. You can also use a technique called “chitting” to encourage the seed potatoes to sprout before planting, which can help control the timing of root growth.
To prevent potatoes from growing roots too late, ensure the soil has adequate moisture and nutrients. Potatoes need consistent moisture, especially when they’re producing tubers. Mulching around the plants can help retain moisture and suppress weeds. Additionally, side-dressing with a balanced fertilizer can provide the necessary nutrients for healthy root growth.
Can I grow potatoes in containers, and how do I care for them?
Yes, you can grow potatoes in containers, which can be a great option for small spaces or poor soil. Choose a container that’s at least 6-8 inches deep and has drainage holes to prevent waterlogged soil. Fill the container with a well-draining potting mix, and plant the seed potatoes 2-4 inches deep. Keep the soil consistently moist, but not waterlogged, and provide full sun to partial shade.
As the plants grow, add more potting mix or straw to the container, leaving only a few inches of the leaves exposed. This will help to produce more tubers. Keep the container in a cool location, and avoid extreme temperatures. Harvest the potatoes when the plants start to yellow and die back, usually after about 70-100 days. Carefully dig around the plants with your fingers to avoid damaging the tubers.
What are some common mistakes to avoid when growing potatoes?
One common mistake to avoid when growing potatoes is planting them in warm weather. Potatoes thrive in cool temperatures, and warm weather can lead to weak and leggy growth. Another mistake is not providing enough moisture, especially when the plants are producing tubers. Consistent moisture is crucial for healthy root growth.
Other mistakes to avoid include planting seed potatoes that are too old or of poor quality, not hilling the soil around the plants, and harvesting the potatoes too early or too late. It’s also essential to rotate the potato crop to avoid depleting the soil of nutrients and to reduce the risk of disease. By avoiding these common mistakes, you can enjoy a healthy and productive potato crop.
How do I store harvested potatoes to keep them fresh for a longer period?
To store harvested potatoes, choose a cool, dark location with good ventilation. The ideal storage temperature is between 40°F and 50°F (4°C and 10°C), and the humidity should be around 80-90%. Avoid storing potatoes in direct sunlight or near heat sources, as this can cause them to sprout or rot.
Store the potatoes in a breathable container, such as a paper bag or a ventilated plastic bag. Don’t wash the potatoes before storing them, as excess moisture can lead to rot. Instead, gently brush off any dirt or debris. Check on the potatoes regularly to remove any that are rotting or sprouting, as these can affect the rest of the crop.
Can I grow potatoes in the same spot year after year, or do I need to rotate the crop?
It’s not recommended to grow potatoes in the same spot year after year, as this can lead to soil-borne diseases and pests. Potato crops can deplete the soil of nutrients, especially potassium, and rotating the crop can help to maintain soil fertility. Additionally, rotating the crop can reduce the risk of disease and pests, such as the potato cyst nematode.
Rotate the potato crop with a non-solanaceous crop, such as corn, beans, or wheat, to create a balanced and diverse crop rotation. This will help to maintain soil health and reduce the risk of disease and pests. If you don’t have space to rotate the crop, consider using a crop rotation plan that includes cover crops or green manures to improve soil fertility and structure.
What are some common pests and diseases that can affect potato crops, and how can I manage them?
Some common pests that can affect potato crops include the potato beetle, aphids, and wireworms. To manage these pests, use a combination of cultural, physical, and chemical controls. For example, you can use row covers to prevent potato beetles from reaching the plants, or hand-pick the beetles and destroy them.
Common diseases that can affect potato crops include late blight, scab, and powdery scab. To manage these diseases, use a combination of cultural and chemical controls. For example, you can use resistant varieties, practice good sanitation, and apply fungicides as needed. It’s also essential to monitor the crop regularly for signs of pests and diseases, and take action quickly to prevent the problem from spreading.
