FORT MYERS, Fla. - Southwest Florida is bracing for another round in the deep freeze. With temps set to plummet near freezing again, plants and people are covering for the third time this month.

"We're actually sold out of frostcloth right now," said Karen Sullivan at Bayshore Garden Center in North Fort Myers.  

Questions were coming in all day, especially from newly arrived seasonal residents.

"They came down here for our wonderful weather, and they really don't know what to do with their Florida plants," Sullivan said.

The garden center reminded people not to water plants as protection, but cover them up.

Palm trees can even suffer damage, particularly the more tropical varieties.

"There's palms that we can grow here that are cold tolerant, you won't have any problem with them," said Bayshore Garden Center owner Joe Scott.

Large-scale growers are also back with the same precautions as a few weeks ago, only with less foliage to protect after the last cold snap led to nearly $200 million in damage in Hendry County alone.

Meantime, what should be a bustling post-holiday crowd on the beach instead a mere trickle of the visitors for the shops and performers. But the heartiest visitors from up north aren't letting a little Florida chill stop them from enjoying the smaller crowds on the sand.

"I don't mind the sweatshirt, its better than the snow parkas, and tooks and winter boots," said one Canadian visitor.
