How cold hardy are staghorn ferns?
Click to see full answer .
Consequently, do staghorn ferns freeze?
As a rule, staghorn ferns are not at all tolerant of cold temperatures. There are a couple of exceptions, such as the bifurcatum variety that can survive temperatures as low as 30 F. They will die at or above freezing temperatures if they don't have adequate protection.
Likewise, what is the lowest temperature a Boston fern can tolerate? The lowest minimum temperatures for USDA zone 10 are 30 to 35 degrees Fahrenheit. Boston ferns die if exposed to lower temperatures . The best indoor temperature range for these voluptuous plants is between 68 and 78 F, notes Colorado State University Extension.
Similarly, you may ask, what temperature is too cold for ferns?
On the coldest end of the scale, hardy ferns can survive temperatures down to minus 50 degrees Fahrenheit . However, hardy ferns in USDA zones 2 through 6, tend to be semi-evergreen. In most cases, it is safe to leave many hardy ferns outdoors all winter long. A few, however, are only cold-hardy to USDA zones 6 or 7.
Can ferns survive 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.
