I killed off many of these before I got the hang of growing them. They do not like heat, nor do they like to have the soil be dry.
Soil should be kept moist. Do not let the soil go dry. Put the fern in the sink, let the water run over it. Once the water stops coming out of the bottom of the pot hang it back up.
They prefer it to be both cool and damp. So if you have a drafty window or door you can place the plant near it’ll be much happier. Or place it near your humidifier.
Light needs are minimal for ferns. They will be happy in a north or east facing window. Or you can place them in the interior of a well lit room. They are one of the few plants that can do well indoors away from a window.
Ferns are excellent plants for cleaning the air in your home.
