How to Care for the Plant
Water
Keep the soil moist. Ferns are water-loving plants, which means that they do best in soil that is evenly and consistently moist. To keep your ferns happy, water them thoroughly whenever it feels like the top of the soil is starting to dry out.
Pruning
As a rule, ferns don't really need pruning. Ferns in nature are generally self-cleaning and will release old fronds as they die.
Temperature
60-80°F (16-27°C). Not frost resistant.
