South Florida farmers planned to protect their crops while temperatures fall over the next few days.

At Knaus Berry Farm, longtime grower Herb Grafe knew his plan Wednesday.

"All farmers try to plan ahead of time," he said. "This aluminum pipe in here is what we run the water through whenever we start to see ice."

A coating of water helps protect the plants and a layer of ice keeps temperatures stable.

"They'll be fine as long as you water, they'll be fine," he said. "Strawberries will tolerate cold a lot better than other crops will."

Temperatures are forecast to be in the 30s.
