Asplenium is native to the rain forests of Asia, Africa, and Australia which explains why high humidity is essential for it to thrive.
Light
Does well in medium indirect light.
Water
Keep the soil moist but never soggy at all times.
Fertilizer
Fertilize once or twice in the spring and summer, when the fern is actively growing. Over-fertilization causes more problems for this fern than never fertilizing at all. Use a balanced plant food diluted to 1/2 the recommended strength.
Temperature
Likes temperatures between 70°-90°F (21.1°-32.2°C) during the day and about 10° cooler at night. These ferns grow slowly when the temperature is not within this range and leaves are damaged by hot or cold drafts. The base of the fronds turn yellow when the temperature is too warm.
Humidity
High humidity is essential. Lack of humidity causes major problems: the entire leaf may turn yellow, the tips of the leaves may turn brown, and the plant may stop growing. If the humidity in is too low, consider putting your fern on a wet pebble tray, be sure the plant is sitting on pebbles and not in the water. Pebble tray is much better than misting as leaves doesn't like water.
Soil
Grows well in a soil high in organic material that holds water but is still loose and not heavy and clay-like.
Pot Size
When it grows and its roots fill the existing container, re-pot to the next size container.
Non-poisonous houseplant.
