Freezing temps damaged my potato plants. Should I replant?

Question:

Freezing temperatures in May damaged my potato plants. Will I need to replant?

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.  There is no need to replant the potatoes.
