Ferns are fast-growing and require special care and attention in order to thrive indoors as houseplants. Most ferns needs consistent humidity and moisture. While they don’t require pruning, regularly removing any dead or dying fronds will help to encourage new and healthy growth on a consistent basis.
Ferns thrive in medium indirect light to low light conditions. When grown indoors, they do well next to a bright window such as a north-facing window. Avoid harsh, direct sun as this can burn the delicate fronds. When grown outdoors, a shaded location that receives dappled sun is ideal.
A rich, moist but well-draining soil mixture is ideal for ferns. A standard potting mixture with added peat for additional drainage is sufficient.
Most ferns requires sufficient moisture in order to thrive and the soil should never be allowed to dry out completely. Water well once the top one to two inches of soil is dry. Depending on the growing season and the amount of light that your fern is getting, you may need to water your fern multiple times a week to keep it happy.
These ferns can be sensitive to hard water. If you have tap water that has lots of salt, fluorine, or chlorine in it you may need to switch to filtered water.
Temperature and Humidity
Ferns thrive in temperatures between 60-70 degrees Fahrenheit and cannot tolerate frost. When grown indoors, this means that you should keep your fern away from any drafty or cold windows. Ferns are popular additions to bathrooms for this reason.
This species requires abundant humidity and the fronds will quickly turn crispy in dry environments. Adding a humidifier next to your fern will keep it happy indoors, or you can place it on a pebble tray filled with water to increase the humidity around the plant.
