U.D. Department of Agriculture hardiness zones for the Boston fern are 9, 10 and 11, all of which have average low temperatures of -6.67 to 4.44 degrees Celsius. Ideally, the temperature for outdoor ferns is between 18.3 and 35 degrees Celsius, but the Boston fern will tolerate much colder temperatures.
Boston ferns grown in the ground outdoors will die back at first frost and grow back in the spring. Ferns grown in containers outdoors will remain green until the temperatures drop to the 40s. Once the temperatures drop, the green frond will turn yellow over the winter.
