Water: Like most ferns, they like moist soil. So check the soil around every week and if the top inch or so feels dry, then water it. 

Humidity: It really loves moist air, so a bathroom is its dream spot to live. Failing that, misting it regularly will help.

Feed: A weak dose (half strength) of liquid feed every month in the spring and summer will boost growth. 

Toxicity: Non-toxic.
