The Hurricane Fern (Asplenium antiquum ‘Hurricane’) is a distinctive bird’s nest fern known for its twisted, swirling fronds. Bred in the Netherlands in 2014, this plant adds a sculptural element to indoor spaces. Its vibrant green foliage and intriguing growth pattern make it a popular choice, adding natural artistry to desks and tabletops.
Essential Indoor Care Requirements
Light
The Hurricane Fern thrives in bright, indirect light. Placing it near an east or north-facing window provides ideal illumination. If a south or west-facing window is the only option, position the fern a few feet away to prevent direct sun exposure. Direct sunlight, especially during afternoon hours, can scorch the fronds, leading to brown or yellow discoloration. Conversely, insufficient light may result in pale, weak fronds and a slower growth rate.
Watering
Consistent moisture is important for a healthy Hurricane Fern, though it should never sit in soggy soil. Water when the top inch of soil feels dry. The frequency of watering varies based on factors like temperature, humidity, and pot size. Use filtered, distilled, or rainwater to minimize mineral buildup, as ferns are sensitive to tap water chemicals. Avoid pouring water directly into the central rosette, as this can lead to rot. Instead, water around the edges of the pot.
Humidity
High humidity levels benefit Hurricane Ferns due to their tropical origins. While they tolerate typical indoor humidity, above-average moisture promotes healthier growth. Increase humidity by placing the plant on a pebble tray filled with water, grouping it with other plants, or using a room humidifier. Misting offers temporary humidity and cleans leaves, but it is not a sufficient long-term solution. Avoid over-misting, which can promote fungal growth if air circulation is poor.
Temperature
Hurricane Ferns prefer a stable indoor temperature range, typically between 60°F and 80°F (15°C to 27°C). Maintaining temperatures within this range helps the plant thrive. Temperatures dropping below 60°F can cause damage to the fronds and harm the plant. Shield the fern from sudden temperature fluctuations, such as cold drafts from windows or direct airflow from heating and air conditioning vents.
Soil
The ideal soil for a Hurricane Fern is well-draining, aerated, and rich in organic matter. A suitable potting mix includes peat moss, perlite, and pine bark. This combination ensures moisture retention while allowing excess water to drain freely, preventing root rot. Good drainage is important for the plant’s root health, as consistently waterlogged soil can suffocate the roots. Since these ferns are epiphytic, they do not develop extensive root systems, making proper drainage even more important.
Fertilization
Hurricane Ferns are not heavy feeders and benefit from light fertilization during their active growing season, typically spring and summer. A balanced, liquid houseplant fertilizer diluted to half or quarter strength is recommended. Fertilize once a month during this period. During fall and winter, when growth slows, reduce or cease fertilization. Over-fertilization can lead to nutrient burn, which may manifest as browning of the frond tips.
Repotting
Repotting a Hurricane Fern is not a frequent requirement, as these plants generally prefer to be slightly root-bound. It is typically necessary every 2 to 3 years, or when the plant has visibly outgrown its current container. The best time for repotting is during spring or early summer. Choose a new pot only one size larger than the current one to minimize stress.
To repot, gently remove the fern from its old container, disturbing the root ball minimally. Inspect roots for rot or damage. Place a layer of fresh, appropriate soil mix at the bottom of the new pot, position the fern, and fill around the root ball, ensuring the plant is at the same depth. After repotting, water thoroughly to help it settle.
Addressing Common Problems
Brown leaf tips or edges are common indicators of low humidity or inconsistent watering. Increasing the surrounding humidity and maintaining a consistent watering schedule can help resolve this. If fronds appear yellow, it could suggest overwatering or too much direct light. Check soil moisture and adjust watering habits, or relocate the plant to a less intense light area.
Drooping fronds indicate underwatering or severe dehydration. A thorough watering should revive the plant, though consistent moisture is important to prevent recurrence. While Hurricane Ferns are generally resistant, common houseplant pests like spider mites, mealybugs, and scale insects can sometimes infest them. Regular inspection helps in early detection. If pests are found, organic pest control methods such as neem oil or insecticidal soap are effective treatments.
