Green Thumb Nursery in Tampa says it has moved its inventory to greenhouses.
"Some of our greenhouses stay up to 65 degrees so they stay pretty warm. We spray some water on the floor. It evaporates during the day and keeps it nice and warm," said Steven Rey, Assistant Manager at Green Thumb Nursery.
"We're expecting it to get down to 29 degrees so that's freezing so a lot of the plants we have here are tropical," added Rey.
