Did You Know?
1. Potatoes can actually survive frost, but only to a certain extent. While a light frost may cause minimal damage to the plant, a severe frost can be detrimental, resulting in the death of the potato plant.
2. The ability of potatoes to survive frost is due to their ability to store starch. This starch acts as a natural antifreeze by lowering the freezing point of the plant’s cells, allowing it to withstand lower temperatures.
3. Interestingly, potatoes that have been exposed to frost have a sweeter taste compared to those that haven’t. The cold temperatures cause the starch in the potatoes to break down into sugars, resulting in a pleasant flavor.
4. To enhance the survival of potatoes during frost, some farmers implement a process called hilling. This involves piling soil around the plant’s base, creating a “hill” that covers the tubers. The mound of soil acts as insulation, protecting the potatoes from freezing temperatures.
5. While potatoes can survive frost, they become more susceptible to diseases and rot after being exposed to extreme cold. It is essential to handle harvested potatoes with care and store them properly to prevent spoilage.
Frost Tolerance Of Potatoes
Potatoes, a staple in many households, are known for their hardiness and ability to survive in various climates. When it comes to frost, most potato varieties can handle a light frost, which typically refers to temperatures between 28-32 degrees Fahrenheit, with little to no damage. However, a hard frost, characterized by even lower temperatures, can pose a threat to potato plants unless provided with proper protection.
In the case of a hard frost, potato plants can still survive if provided with cold protection measures such as a cold frame or row covers. These protective structures act as a shield, shielding the plants from the freezing temperatures. By trapping heat from the surrounding environment, they create a microclimate that helps to preserve the warmth and prevent the plants from freezing.
- Light frost: 28-32 degrees Fahrenheit
- Hard frost: below 28 degrees Fahrenheit

Planting And Preparation Of Seed Potatoes
When it comes to planting potatoes, seed potatoes are highly recommended over regular potatoes bought from the grocery store. Seed potatoes are whole potatoes saved from the prior year’s crop and carefully selected for their desirable qualities, such as disease resistance, high yield, or specific taste and texture characteristics.
Before planting the seed potatoes, it is crucial to check their condition. Ensure that the potatoes’ eyes are not damaged, rotten, or have already sprouted and broken off. The eyes are the small indentations on the surface of the potato where sprouts emerge. Healthy and viable seed potatoes should have 2-3 eyes each, providing the potential for multiple sprouts and successful growth.
Seed potatoes can be planted either as whole potatoes or cut into pieces, with each piece containing 2-3 viable eyes. However, it is important to note that some potato varieties have fewer eyes per potato. In such cases, it is best to plant the whole potato to ensure sufficient sprouts for healthy growth.
After selecting the appropriate planting method, seed potatoes should be planted 2-3 inches deep and about 1 foot apart, with rows no closer than 3 feet apart.
When planting, it is important to consider the moisture level of the soil. If the soil is extremely dry, it is advisable to water it before planting. However, caution must be exercised not to overwater, as excessive moisture can lead to rotting and other undesirable conditions for potato growth.
- Use seed potatoes, not regular potatoes from the grocery store
- Check seed potatoes for healthy eyes and viability
- Plant whole potatoes or cut pieces with 2-3 viable eyes
- Plant seed potatoes 2-3 inches deep and 1 foot apart
- Rows should be at least 3 feet apart
- Consider soil moisture level when planting to avoid overwatering
“Good soil is needed for good potatoes.” – Irish proverb
Managing Frost Damage To Potato Plants
While potatoes can survive light frosts, it is crucial to be aware of the potential damage that can occur in cases of frost exposure. Frost damage often manifests in the form of ruptured cells or shock, which can impair the plant’s overall health and growth. However, it is important to note that frost damage is more commonly observed on the leaves of the plant rather than the actual potatoes underground.
In the event of frost damage, potatoes have the ability to recover, but this may result in delayed maturity. The severity and length of the frost damage, as well as its recurrence, play a significant role in determining the plant’s ability to bounce back. If there is repeated frost damage, the energy reserves within the tubers may become depleted, eventually leading to the death of the plant.
To mitigate the risk of frost damage, it is advisable to protect potato plants either through preventive measures or by adjusting planting times. Protective measures include covering the plants with a tarp, blanket, or floating row cover during frost events. These covers act as a barrier, shielding the plants from direct exposure to the freezing temperatures. For sustained cold temperatures, additional protective measures may be required.
Timing And Harvesting Potatoes Before Frosts
Timing is crucial for a successful potato harvest, particularly in avoiding autumn frosts. Frozen potatoes can be rendered inedible and unsuitable for storage, so it is important to harvest them before the frosts occur. However, if the ground is not completely frozen, the potatoes that remain underground will generally be unaffected.
It is worth noting that potatoes have different maturation periods, which depend on the specific variety being cultivated. Harvesting too early can result in small, underdeveloped potatoes, while harvesting too late can increase the risk of frost damage. Therefore, closely monitoring the plants’ maturity and planning the harvest accordingly is highly recommended.
Protective Measures For Potato Plants During Frost Events
Protecting potato plants during frost events is crucial to minimize damage and ensure a successful harvest. There are several measures that can be taken to provide adequate protection. One effective method is to cover the plants with a tarp, blanket, or floating row cover to shield them from the freezing temperatures.
Watering the plants before frost can also help in maintaining the soil’s warmth around the roots. Moist soil has the ability to absorb more heat compared to dry soil, creating a protective layer for the roots. However, it is important to avoid watering the leaves as this may cause them to freeze and break off.
Another useful technique is to mulch the potato bushes. Mulch acts as an insulator, regulating the temperature of the soil and keeping it warmer during cold weather. By using commercially available mulch or natural components such as straw, hay, or leaves, a thick layer can be created to provide significant insulation for the plants.
while potatoes have a certain level of frost tolerance, precautions and protective measures must be taken to ensure their survival and maximize yield. By properly preparing the seed potatoes, timing the planting and harvest, and implementing protective measures during frost events, gardeners can increase their chances of cultivating healthy and prosperous potato plants.

Frequently Asked Questions
Will potatoes survive frost damage?
Yes, potatoes have the ability to survive frost damage. While the shoots of potatoes are sensitive to freezing temperatures, the plants can recover from severe damage. In the event of severe frost damage, where aboveground growth dies, the potatoes have a remarkable ability to regenerate new growth within 10 to 14 days. This resilience allows potatoes to adapt and endure freezing conditions, ensuring their survival.
What temperature will potatoes freeze?
The freezing temperature of potatoes can vary depending on their location and exposure to freezing temperatures. Generally, frost damage occurs when the temperature of potatoes drops below approximately 30 degrees Fahrenheit, causing the tuber tissues to freeze. However, potatoes that are closer to the surface are more vulnerable to freezing temperatures compared to those buried deeper in the soil. Therefore, the temperature at which potatoes freeze can range, but it is crucial to protect them from freezing temperatures to avoid potential frost damage.
What happens if potatoes get cold?
If potatoes get cold, they may undergo a chemical reaction that results in a change in color when cooked. Exposure to low temperatures can cause potatoes to turn black or grey during the cooking process. To prevent this undesirable outcome, it is crucial to store potatoes at a temperature range of 45°F to 55°F. By maintaining the appropriate temperature, you can ensure that your potatoes retain their natural color and remain enjoyable to eat.
Is it OK to eat frostbitten potatoes?
Yes, it is generally safe to eat frostbitten potatoes. While freezer burn may cause dry spots on the surface of the potato, it does not make the food unsafe for consumption. The grayish-brown spots are simply a quality issue due to air exposure, rather than a food safety concern. If you trim off the affected areas, the remaining potato can still be cooked and enjoyed without any risks to your health.
