However, Leatherwood ferns do not do well when the temperature drops below 40 to 45 degrees. They can survive the occasional freeze, but if the temperature will drop to 30 degrees or so for five or six days in a row, it's best to take the ferns indoors if they are grown in pots not to cover them.
A light sheet or blanket around your Leatherwood ferns should be enough, but never cover your Leatherwood ferns with plastic. You can use black plastic, which will reflect the sun's heat when it gets warm, but clear plastic alone will produce a greenhouse effect. Always have at least a sheet or a thin blanket as protection before laying black plastic around it. Try to teach your cats and dogs to stay out of your fern growing areas.
