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.
What temperature is too cold for potatoes?
Cold pulp temperature consequences: Avoid harvesting potatoes with pulp temperatures less than 45°F. For varieties susceptible to Fusarium dry rot (for example Clearwater Russet, Umatilla Russet) it is recommended to harvest at pulp temperatures above 50°F.
Can potatoes survive freezing?
The answer is yes and no. Potatoes (Solanum tuberosum) are perennial plants and some cultivated potatoes can be quite hardy. The ability of cultivated forms to survive winter cold depends on the variety (there are over 4,000 known types), but most will not withstand hard freezes.
Should I cover my potato plants?

Will potatoes regrow after a frost?
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.
Will frozen potatoes sprout?
Storing seed potatoes at a temperature below 32F freezes and damages the potatoes. But some seed potatoes will still sprout and grow new plants after suffering freeze damage.
How do I protect my potato plants from frost?
Protection for Planted Potatoes
A light mulch of straw over newly emerged potato plants traps ground warmth and protects the tender plants from freezing temperatures. Row covers offer better protection, increasing night temperatures in the potato row by 5 F. Fabric row covers work better than either plastic or paper.
How do you protect potatoes in the winter?
Firstly, wait for the foliage to turn yellow and die back before removing it. For light, free draining soils, piling on some more earth along the row, followed by a deep mulch of straw should be sufficient to keep the potatoes protected until they are ready to be lifted.

According to the Oregon State University Extension, you should avoid covering the leaves when hilling potatoes.
Why do my potato plants look dead?
Potato early die is also known as Verticillium wilt, named for the wilting symptoms that appear once the plant is infected by the fungus. The disease is characterized by the decline of plants many weeks earlier than normal maturity (Figure 1).
Should you pick flowers off potato plants?
When you see flowers on your potato plants, I recommend cutting them off for two main reasons. First of all, you don’t want the flowers to produce a fruit that small children or pets might be tempted to eat. Secondly, pruning the flowers is a great way to increase production of spuds.
Why did my potato plants not produce potatoes?
Where many gardeners have gone wrong when their growing potato plants are not producing is around bloom time, when the potato tuber begins to bulk. Excessive application of nitrogen at this time will result in no potatoes on your plants or low potato yields.
