How cold is too cold for ferns?
Accordingly, what is the lowest temperature a Boston fern can tolerate?

Furthermore, can Ferns stay outside in winter? Ferns grown in containers outdoors may survive the winter in very cold climates if you bring them indoors. Most ferns like moisture, but not when water is sitting in the pot's saucer. Water regularly, and don't let the soil dry out completely.
Similarly, it is asked, what temperature can ferns survive?
Temperature: These ferns can survive the occasional blast of cold, down to 50 F or even slightly colder for a few hours. However, they really thrive between 60 and 75 F.
Will Frost kill my ferns?
Texas A&M says a major freeze, one that's unusually cold or lasts for a long time, can kill off a fern. Ferns vary in their cold-hardiness, but a fern native to the area should be better able to survive freezing conditions that are normal for the region. If the fern survived, it will produce new growth in spring.
