Crispy Wave Fern Indoor Care
If you’re a fan of ferns, you’re probably aware of how versatile they can be in gardens and homes. They’re great in rock gardens, in both shade and sun, and work wonders as houseplants. But with so many varieties of houseplant ferns to choose from, it can be hard to decide which one is best for your space. One standout choice for indoor gardeners is the Crispy Wave Fern, also known as the Japanese Asplenium nidus.
This fern is easy to care for, adaptable to different growing conditions, and makes a gorgeous addition to any space. While it’s not too difficult to grow, it can be a bit picky about its environment. Over the years, I’ve learned a few tips and tricks to help keep this plant thriving indoors, and I’m here to share them with you!
What is a Crispy Wave Fern?
The Crispy Wave Fern is a cultivar of the low-maintenance Asplenium nidus. It’s also known as the Bird’s Nest Fern because of its unique leaf shape that radiates outwards from the center, resembling a bird’s nest. It’s a popular indoor plant because of its beautiful, glossy, green leaves that give a lush tropical look.
This fern is originally from the tropical forests of Japan and Taiwan but has since spread to other parts of Asia, Africa, Australia, and Europe. Not only does the Crispy Wave Fern brighten up your space, but it also helps purify the air by removing carbon dioxide and releasing fresh oxygen.
How Big Does a Crispy Wave Fern Get?
Crispy Wave Ferns are non-flowering plants that typically reach up to 2 feet (61 cm) in height. They are perfect for indoor spaces, adding a nice dose of greenery without taking up too much room. These ferns do especially well in small pots or hanging baskets where their feathery fronds can cascade elegantly.
If you provide the right conditions—like high humidity and consistent temperature—this fern can grow much larger outdoors. But indoors, it’s an excellent air-purifying plant that works beautifully as a living accent piece in rooms like the living room, bedroom, or kitchen.
Planting and Care Requirements for Crispy Wave Fern
To help your fern thrive, here are some key growing conditions to follow:
- Soil: The Crispy Wave Fern loves moist but well-drained tropical soil. A tropical soil mix with good drainage works best. You can use a mix of organic potting soil, coarse sand, and perlite to create the perfect soil for this fern. Make sure the soil doesn’t retain too much water as that can lead to root rot.
- Water: Water your fern about twice a week to keep the soil lightly moist, but not soggy. Overwatering can cause the roots to rot. If you’re unsure, always check the soil moisture before adding more water. Tap water can be used, but it’s a good idea to let it sit for a few hours to help remove any chlorine or minerals that may harm your plant.
- Sunlight: Place your fern in indirect light for 3 to 6 hours a day. Avoid direct sunlight as it can scorch the leaves. A spot near a window with filtered light is ideal.
- Temperature: The ideal temperature range for a Crispy Wave Fern is between 70–90°F (21–32°C). Make sure to avoid temperature extremes—no lower than 55°F (13°C) or higher than 100°F (35°C). Keep the temperature stable for optimal growth.
- Fertilizing: During the growing season (spring and summer), feed your fern once a month with a half-strength liquid fertilizer. It’s best to dilute it to avoid overfeeding. Slow-release granules can also be used in the spring for an easier, hands-off approach.
- Humidity: This fern thrives in high humidity (60–90%). If your indoor space is dry, especially during the winter months, you can mist the plant twice a day using a spray bottle to keep the air moist. Alternatively, using a humidifier can help create the perfect environment for your fern.
Propagating a Crispy Wave Fern
There are a few ways to propagate your Crispy Wave Fern: from spores, by division, or using leaf base bulbils. Here’s how you can do it:
Propagating from Spores:
- Collect spores in mid-summer from the underside of the fern’s fronds. Look for dark brown or black sporangia to make sure the spores are ripe.
- Cut the frond with ripe spores and place it in a plastic bag for 48 hours. Tap the bag to release the spores.
- After the spores settle, transfer them to sterilized compost (made by boiling water over it) to prevent any bacterial or fungal growth.
- Sprinkle the spores lightly on the compost and place it in a spot with indirect sunlight. Keep it lightly watered, and you should start seeing a green film covering the soil in about a month or two.
- Once the new fronds are big enough, remove them from the plastic bag and let them acclimate to normal air. When they’re ready, transfer them to a larger pot.
Propagating by Division:
- Divide the rhizome of your mature fern into 2-4 sections, making sure each division has healthy roots and shoots.
- Separate the roots carefully and plant them into their own pots. Water well and treat the new plants like you would a mature one.
Why Are the Leaves Drooping?
If your Crispy Wave Fern’s leaves are drooping, it might be due to overwatering, underwatering, or insufficient light. Make sure it’s getting enough indirect sunlight and that the soil is consistently moist but not soggy.
Another reason could be pest infestations like aphids or mealybugs that suck the moisture from the leaves, causing them to sag. If you notice any pests, remove them immediately with a mild soap solution or insecticidal soap.
Common Issues with Crispy Wave Fern
- Yellowing Leaves: This could be due to too much direct sunlight, too little water, or insufficient nutrients.
- Brown Tips: This is often a sign of low humidity or underwatering.
- Leaf Spots: Keep an eye out for leaf spots, which can be caused by overwatering or pests. Prune off damaged leaves to help the plant recover.
Final Tips for a Thriving Crispy Wave Fern:
- Keep the soil moist but well-drained.
- Water from above, ensuring the rosette isn’t sitting in stagnant water.
- Ensure your fern gets plenty of indirect sunlight.
- Provide high humidity, especially in dry climates.
- Trim damaged leaves and check for pests regularly.
By following these tips, you can enjoy a healthy, lush, and beautiful Crispy Wave Fern that will thrive for years in your home!
FAQs for Growing and Caring for Crispy Wave Fern
1. What are the ideal growing conditions for Crispy Wave Fern?
Crispy Wave Ferns thrive in bright, indirect light but can tolerate some lower light conditions. They prefer temperatures between 60°F and 75°F (15°C – 24°C) and high humidity levels, making them perfect for bathrooms or kitchens. They also enjoy well-draining, slightly acidic soil.
2. How often should I water my Crispy Wave Fern?
Crispy Wave Ferns prefer consistently moist soil, but they do not like to sit in water. Water when the top inch of soil feels dry, and be sure to water thoroughly so that water reaches the roots. Be careful not to overwater, as this can lead to root rot. During the winter months, you can reduce watering slightly, as the plant’s growth slows down.
