Frost damage occurs when the temperature drops below freezing for a prolonged period of time. It can be caused by a number of factors, such as a sudden change in wind direction or temperature, or by the presence of ice crystals in the soil.
In most cases, the damage will be limited to the roots of the plant, but in some cases it may affect the entire plant. Frost damage is most likely to occur during the winter months, when temperatures are low and the ground is covered with snow and ice.
If you suspect that your plant has been damaged by frost, contact your local Extension office for assistance.
