between 29 and 32 degrees Fahrenheit.
Planted potatoes can usually withstand a light frost that happens at temperatures between 29 and 32 degrees Fahrenheit, but a heavier frost can damage your potatoes.

What is the lowest temperature potatoes can survive?

Potato plants can survive a light frost (temperatures of 28 to 32 degrees Fahrenheit), usually with little or no damage. Potato plants can also survive a hard frost (temperatures below 28 degrees Fahrenheit), especially with cold protection (such as cloches or row covers).

Do potatoes need to be covered for frost?

above the soil surface, they are hilled up again. If there is the danger of a late frost, young tender potato plants can be completely covered with this soil to protect them from frost damage. Hilling up potatoes also helps keep weeds down around the potato root zone, so the potatoes are not competing for nutrients.

Will frost damage potato plants?

Answer: Potato shoots (stems) are sensitive to freezing temperatures. Symptoms of freeze damage may vary from blackening of the leaf margins (minor damage) to death of all aboveground growth (severe damage). Fortunately, severely damaged potatoes will send up new growth (shoots) within 10 to 14 days.

Can potatoes get too cold?
