Although potatoes can tolerate some frost, they may suffer from signs of frost damage, including: Frost Protection (how much protection did the plant have against the cold?).Length of Exposure (how long was the plant exposed to the cold?).Cold Severity (how far below freezing is the air temperature?). ![]() In more severe cases, all of the plant that is above ground (shoots and leaves) will succumb to extreme cold.Ī hard frost can cause black edges on the leaves of a potato plant.
