Ferns — or helechos, as they’re known in Spanish — are some of the oldest, most resilient, and most beautiful plants on Earth. They’re a popular choice as houseplants and in gardens, prized for their lush foliage, graceful shapes, and air-purifying qualities.
Did you know there are nearly 12,000 different kinds of ferns? That’s a lot of variety!
This article will walk you through the wonderful world of ferns, covering everything from the different types you can grow indoors to how to care for them, propagate them, choose the right spot, and troubleshoot common problems.
Ferns: What to look for
Ferns are primitive plants that don’t produce flowers or seeds. Instead, ferns reproduce using spores.
When you’re trying to identify a fern, the key things to look for are its fronds or leaves, and their structure. Fern fronds can be simple, or they can be divided into leaflets called pinnae.
With the right care, most ferns will last for a decade or longer.
Male and female ferns
Ferns reproduce through spores, which are usually found on the underside of the fronds. These spore-producing structures are called sori (the singular is sorus).
It’s generally not possible to tell male and female ferns apart just by looking at them, although some fern experts say that the shape and placement of the sorus may offer a clue.
Popular Types of Ferns
Ferns come in a dizzying array of shapes and sizes. Here are a few popular types you might consider:
- Boston Fern (Nephrolepis exaltata): The classic! They like indirect light and moist soil. Give them fertilizer every couple of months. Their leaves can grow up to a meter long.
- Asparagus Fern (Asparragus densiflorus): These are tougher than they look. They can even handle full sun if you water them often. If you’re growing them in containers, though, partial sun is better.
- Male Fern (Nephrolepis biserrata): A robust fern perfect for outdoor spaces.
- Bird’s Nest Fern (Asplenium nidus): These guys love filtered light. Think of a forest floor.
- Rabbit’s Foot Fern (Davallia fejeensis): They get their name from the fuzzy rhizomes that creep over the edge of the pot. Keep their soil slightly moist and water them about once a week.
- Lemon Button Fern (Nephrolepis cordifolia ‘Duffi’): A cute, compact fern with a refreshing citrus scent.
- Kimberly Queen Fern (Nephrolepis obliterata): These are super easy to care for. Just keep them in a slightly moist environment, and they’ll thrive.
Caring for Your Fern: Essential Tips
Ferns are a great way to add a bit of low-maintenance greenery to your home, but they do have some specific needs. Here’s how to keep your fern happy and thriving:
Watering
Your fern will likely need regular watering to stay healthy. The key is to keep the soil consistently moist, but not soggy. You don’t want to drown your fern!
Before you water, check the soil moisture. Stick your finger about an inch into the soil. If it feels dry, it’s time to water. If it’s still damp, wait a day or two and check again.
Fertilization
Ferns benefit from occasional fertilization, especially during the growing season (spring and summer). Use a balanced liquid fertilizer, but dilute it to half strength to avoid burning the roots. Fertilize every 4-6 weeks during the growing season.
Light
Ferns love bright, indirect light. Direct sunlight can scorch their delicate fronds, so avoid placing them in a spot where they’ll get harsh rays. An east-facing window is often ideal, or a spot a few feet away from a south- or west-facing window.
Repotting
Eventually, your fern will outgrow its pot. You’ll know it’s time to repot when you see roots growing out of the drainage holes, the soil compacts and doesn’t drain well, or the leaves start to yellow or wilt even when the soil is moist.
To repot your fern, choose a pot that’s only slightly larger than the current one. Use a rich, well-draining potting mix. A blend of peat moss and worm castings works well. Gently remove the fern from its old pot, loosen the roots a bit, and place it in the new pot. Fill in around the roots with fresh potting mix, water well, and you’re done!
Growing More Helechos
If you want to grow more helechos, you have a few options:
- Division: Some ferns spread through rhizomes (horizontal underground stems). You can dig up the plant, separate the rhizomes, and plant them in their own pots.
- Spores: Ferns don’t produce seeds. Instead, they produce spores on the underside of their fronds. You can collect these spores and sow them in a sterile potting mix. This method takes patience.
- Cuttings: Some ferns can be propagated from stem cuttings. Just take a cutting and root it in water or soil.
Propagating ferns can be a fun way to expand your collection or share them with friends!
Where to put your fern
Where you put your fern is critical to its survival. Ferns love indirect light, steady humidity, and temperatures between 65-75°F (18-24°C).
The best places for ferns are:
- Bathrooms. The humidity from your showers and baths will keep your fern happy.
- Living rooms (with the right light). Keep your fern away from direct sunlight. Filtered light near a window is ideal.
- Terrariums. Terrariums mimic the fern’s natural environment. They’re also great for maintaining humidity.
Common Problems and Solutions
Even with the best care, your helecho might run into a few snags. Here’s how to troubleshoot:
Pests
Keep an eye out for these common fern pests:
- Spider mites
- Mealybugs
- Aphids
If you spot any unwanted visitors, try these pest control solutions:
- Regular cleaning: Gently wipe down the fronds to remove pests.
- Humidity control: Pests often thrive in dry conditions, so maintaining humidity can help.
- Isolation: Keep affected plants away from healthy ones to prevent the problem from spreading.
- Natural remedies: Insecticidal soap or neem oil can be effective against many common fern pests.
Drying Out
Is your helecho looking a little crispy? Here’s why that might be happening:
- Insufficient water
- Low humidity
- Too much direct sunlight
- Extreme temperatures
To keep your fern from drying out, try these solutions:
- Adjust watering: Water more frequently, ensuring the soil stays consistently moist (but not soggy).
- Increase humidity: Use a humidifier or place the fern on a pebble tray filled with water.
- Move to a shadier spot: Direct sunlight can scorch the delicate fronds.
The Symbolism and Feng Shui of Ferns
Across different cultures, ferns hold distinct symbolic meanings. In Feng Shui, they represent humility and prosperity. In Japan, they’re considered good luck.
Many people use ferns in Feng Shui practices to cultivate harmony and balance in their homes. Where you place your fern matters. The right placement is thought to generate positive energy and improve the flow of chi.
