How to Grow Bird's Nest Fern in Water? Master Temperature, Light, and Water Change Techniques
The leaves of the bird's nest fern grow outward, naturally forming a hollow "funnel" in the center, which looks just like a bird's nest from a distance, and that is how the name "bird's nest fern" came about. Placing it indoors adds a touch of tropical flair and brings a vivid touch of natural greenery to the home. Below is a summary of practical care points for growing bird's nest fern in water, which even beginners can follow.
Preparation and Basics Before Water Culture
For water-culturing bird's nest fern, it is recommended to choose a smaller single plant, wash the roots clean using the potted root-washing method, and then transfer it into a water culture container, as this makes it easier for the plant to adapt to the water culture environment. There are a few things to remember in daily care: during the growing season, mist the leaves frequently to raise the surrounding air humidity; fertilizer supply must also keep up, because once fertilizer is lacking or the temperature is too low, the leaf edges are prone to browning. The placement should be in diffused light, and direct sunlight must be avoided, especially in summer when shading is essential. In winter, the room temperature should preferably stay above 8°C; as for water changes, change the water about once every 20 days in summer, and the interval can be longer in winter.
Five Key Factors in Water Culture Care
Temperature: The suitable growing temperature for bird's nest fern is 16°C to 27°C. When the temperature drops below 10°C, the plant's growth will stall and the leaf color will lose its luster. In winter, it is best to keep it above 15°C; if conditions do not allow, at least keep it above 5°C, otherwise the leaf edges will turn brown and frost damage may even occur.
Light: Bird's nest fern is a semi-shade plant and is not tolerant of strong light. During the growing period, it does not need intense direct sunlight and diffused light is sufficient. It can be placed near a window to make use of naturally diffused daylight, and direct sunlight should be avoided as much as possible in summer.
Humidity: Mist the leaves and the surrounding area of the bird's nest fern every day to retain moisture, and this can be done twice a day; you can also gently wipe the leaves with a damp towel, which both increases air humidity and cleans the leaf surface at the same time.
Ventilation: Bird's nest fern can only grow well in an environment with air circulation. The place where the water culture container is placed should have windows opened regularly to allow indoor and outdoor air to circulate, ensuring fresh outside air enters the room.
Nutrient solution: Generally, it is fine to directly choose a commercially available nutrient solution specially made for water culture. Note that tap water should first be left to sit for a day, and only after the water temperature approaches room temperature and the chlorine in the water has evaporated should the nutrient solution be added in proportion.
Water Change Frequency and Precautions
Water changes also require attention to detail. If using tap water, it should be left to sit for a day in advance so that chlorine can escape and the water temperature becomes moderate before use. In summer, change the water about once every 20 days, and the interval can be longer in winter. If the water quality stays clean, the plant grows vigorously, and there is no root rot, it is fine to appropriately extend the water change time, but the amount of water lost to evaporation in the container should be replenished in time. In addition, the flower meaning of the bird's nest fern is "unique, fragrant, ever green." Legend has it that it is the sushan flower that does not compete for beauty with peonies, lotuses, chrysanthemums, or plum blossoms, quietly keeping its green through all four seasons, making it more than suitable to keep a pot at home.
