A potato plant can survive light frost in spring. According to the Michigan State University Extension, a light frost means temperatures of 28 to 32 degrees Fahrenheit (-2 to 0 degrees Celsius). Potato plants can survive light frost, but hard frost may damage the leaves and shoots in some cases.
When we were writing we ran into the question “Do potatoes die in Frost?”.
Potato plants tolerate light frost. Potato leaves survive light frosts with little injury, but leaves and stems die back to the ground in colder temperatures. Seed potatoes send up new shoots to replace frost-killed tops.

While researching we ran into the query “How long does it take for potatoes to recover from frost?”.
If a potato plant dies back to the ground due to early spring frost, it may send up new shoots. In a case of major frost damage, the leaves and shoots above ground may not recover. However, according to the Iowa State University Extension, the potato plant will send up new shoots in 10 to 14 days .
A hard frost means temperatures less than 28 degrees Fahrenheit (-2 degrees Celsius). However, temperatures below 28 degrees Fahrenheit could kill the part of the potato plant above the soil. At that point, the plant would need to start from scratch by sending up new growth, costing time and energy.
Will potatoes recover from frost damage?
In some cases, a potato plant can recover from frost damage. In cases of minor frost damage, the plant’s shoots will continue growing and producing new growth. If a potato plant dies back due to frost, it may send up new shoots. In a case of major frost damage, the leaves and shoots above ground may not recover.
Should you worry about frost damage to potato plants?
Potatoes are a cool weather crop, but that doesn’t mean they are invincible .
A normal planting depth of 1 to 3 inches protects seed potato pieces from frost damage even when a hard freeze hits your vegetable garden. Potato leaves survive light frosts with little injury, but leaves and stems die back to the ground in colder temperatures.
What happens to potatoes when they freeze?
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).
Do potatoes freeze in the spring?
Some springs have an unpredictably late “killing frost ,” which can make your newly emerged potato plants freeze . The green foliage will turn black, become limp, or the entire plant may fall to the ground. The small potatoes underground are not affected, but the plant on top must survive for potatoes to continue to grow in the soil.
How do you revive a potato plant after a frost?
Tips Potatoes thrive in full sun and sandy loam. Fertilizing a plant immediately after a frost can cause it to go into shock and not recover. Cut old sheets into 1-inch strips to tie potato plants to stakes. Harvest potatoes two weeks after the plants die naturally.
