CAPE CORAL, Fla.-Nursery owners are protecting their inventory after dealing with several days of freezing temperatures. Danny Yates Nursery in Cape Coral is covering trees and plants and also moved their most vunerable plants indoors. They're using heaters as well to keep the plants warm. Many nurseries have closed their doors during the cold weather because their inventory is under protective coverings. Last winter season was difficult for nursery owners because of prolonged cold weather.
