Citrus farmers in California battling cold temps

CALIFORNIA -- Fighting the frost in California is a battle that has sent citrus farmers into an overnight frenzy.

For the second night, farmers watched the thermometer drop in Southern California.

Some resorted to using fire to try and keep their crops from being destroyed by unusually cold temps but there is a silver lining, the fruit that does survive could be even sweeter.

"Whatever doesn't kill them makes them sweeter. So if you can get the mandarins as close to frozen as you can but not frozen, the trees pushes sugar into the fruit and it increases the quality of the fruit," said Dayna Green-Burgeson.

While the mandarin crop may be fine, some produce experts worry about the other citrus crops. There are a billion dollars worth of trees in California.
