Asplenium nidus Crispy Wave is one of the most popular air-purifying indoor house plant. It has large, extremely stiff and curvy fronds that grow from a center crown. The foliage has a distinctive ‘waviness’ which actually increases the surface area of the fronds. According to NASA’s air purifying plant study, it is the number one factor in determining a plant’s oxygen-producing capabilities. The wavy fronds are highly efficient at converting CO2 into oxygen and removes harmful particles from the air.

Common Names: Pleated Birds Nest Fern or Birds Nest Fern.
How to grow and maintain Asplenium nidus Crispy Wave (Pleated Birds Nest Fern):
It prefers moderate, indirect light. Avoid direct sunlight and deep shade.
It grows well in humus rich soil. Use a peat-based potting mix, 2 parts peat and 1 part perlite is one mixture that will be fine. A peat based mixture with organic material is also good. It prefers a soil pH of 5.5 to 6.5.
Water thoroughly during the growing season and always keep the soil evenly moist but never allow your plant to sit in water. You can allow the topsoil to become slightly dry between each watering. During the winter months, reduce watering.
Humidity may need to be improved if it becomes low and the plant is showing signs of being affected by dry air. You can enhance the humidity by standing the plant in a humidity tray, a tray of peat moss or utilize an electronic humidifier.
It thrives well in room temperatures between 65 degrees Fahrenheit – 75 degrees Fahrenheit / 18 degrees Celsius – 24 degrees Celsius are ideal, and no lower than 55 degrees Fahrenheit (13 degrees Celsius).
During spring and summer, fertilize weekly or biweekly with balanced liquid fertilizer diluted by half. Deformed leaves with brown or yellow spots or edges are a sign of too much fertilizer.
Asplenium nidus Crispy Wave can be propagated by spores or tissue culture. Many ferns can be propagated by division, not this species though.
