Maidenhair ferns are popular houseplants prized for their delicate foliage and unique appearance. While they may seem daunting to care for, dividing and propagating these ferns is an achievable task for both beginner and experienced gardeners. Understanding the best practices can help you successfully propagate your maidenhair ferns and enjoy their beauty in multiple locations.

Dividing a maidenhair fern is possible by gently pulling the plant apart and separating it into individual sections, making sure to disentangle any roots and fronds. Spring is the best time to undertake this process as it aligns with the fern’s natural growth cycle. Once divided, each section can be planted in its own container, where it will grow into a new, thriving fern.

It’s important to nurture your separated ferns and provide them with adequate care, which mainly involves proper watering, humidity, and light conditions. By properly dividing and caring for your maidenhair fern, you can ensure the continued health and beauty of this captivating houseplant.

What Is a Maidenhair Fern

Maidenhair ferns belong to the Adiantum genus, which includes around 250 different species found in various countries globally, such as North America. These ferns are popular among gardeners and plant enthusiasts for their delicate and feathery fronds. They can be grown both indoors and outdoors, depending on the specific species and the climate.

The leaves of maidenhair ferns are typically small and fan-shaped, with a unique texture that adds visual interest to any space. These ferns feature wiry, dark-colored stems, providing a stark contrast to their vibrant green fronds. They thrive in environments with high humidity, cool temperatures, and indirect light. As a result, they can be a bit challenging to maintain, but their beauty makes them worth the effort.

Maidenhair ferns are not only appreciated for their aesthetic appeal but also for their air-purifying qualities. They can help improve indoor air quality by removing toxins, such as formaldehyde and benzene.

To care for these ferns, they require consistently moist soil, regular misting, and proper drainage. It’s essential to avoid letting the soil dry out, as this can cause the delicate fronds to wither and die. Pruning and repotting can help maintain the health of your fern, and one method of propagating new maidenhair ferns is by division.

Propagation Methods

Maidenhair fern can be propagated by two main methods: division and spores. These techniques allow you to multiply your fern and maintain its growth in a healthy way.


To propagate your maidenhair fern by division, wait until your plant is mature and well established. When it’s time to repot the fern, which is generally once the roots have filled the current pot, use a clean, sharp knife to divide the fern (soil and all) into sections.

  • Remove the fern from its existing pot.
  • Gently separate the roots, dividing the plant into sections.
  • Plant each section in a new container with fresh soil.
  • Water the newly divided plants well to help them establish in their new pots.

Division is the easiest way to propagate maidenhair fern and suitable for beginners in plant care.


Propagating maidenhair fern through spores is a bit more challenging and may not be a method most gardeners are familiar with. However, it can be fun to explore different propagation techniques. To propagate your fern via spores:

  1. Locate the spores, which are typically found on the underside of the fronds.
  2. Collect the spores by tapping the frond over a piece of white paper. Alternatively, cut off a frond containing the spores and let it dry on a paper in a sunny area.
  3. Prepare a moist, sterile seed starting mix in a shallow container.
  4. Sprinkle the collected spores evenly on top of the seed starting mix.
  5. Cover the container with a clear lid or plastic wrap to maintain humidity.
  6. Place the container in a spot with indirect sunlight and a temperature around 70-75°F (21-24°C).
  7. Keep the seed starting mix moist and wait for the spores to germinate, which can take a few weeks to a few months.

Once the spores have germinated and the new ferns have grown a bit, carefully transplant them into their own containers.

How to Divide a Maidenhair Fern

Maidenhair ferns are known for their delicate, wispy foliage that adds a touch of elegance to any indoor or outdoor space. However, these plants can outgrow their containers over time and may need dividing to keep them healthy and maintain their shape. In this section, we’ll discuss the proper tools, materials, and step-by-step instructions for dividing a maidenhair fern effectively.

Tools and Materials

To successfully divide a maidenhair fern, you will need the following tools and materials:

  • A clean, sharp knife or scissors
  • A new pot or container with drainage holes
  • Fresh, well-draining potting mix
  • Watering can or clean container for bottom-watering
  • Gloves (optional)

Step-by-Step Guide

  1. Water the fern: Two days before dividing your maidenhair fern, generously water the plant. This ensures that the fern is well-hydrated, as it will have a diminished ability to absorb moisture for a week or two after the division process due to a compromised root system.
  2. Remove the fern from its container: Gently remove the maidenhair fern from its pot, trying not to damage the roots if possible. If planted outdoors, use a shovel to dig up the fern, taking care not to damage the root ball.
  3. Inspect the root ball: After removing the fern from its container, brush off and shake loose as much soil as you can from the root ball. Ferns tend to have tight, interlocking root balls, so it might be difficult to remove much soil.
  4. Make the cut: Using a clean, sharp knife or long serrated knife, carefully cut the root ball into sections. This is best done in spring, as this is the ideal time for dividing ferns.
  5. Plant divided sections: Prepare the new containers with fresh, well-draining potting mix. Plant each divided section into its new container, making sure that the root ball is adequately covered with soil.
  6. Water the new plants: Water each newly planted section from the bottom, as this is the best method for watering maidenhair ferns. Be careful not to overwater, as too much moisture can cause root rot.

By following these steps, you can effectively divide and propagate your maidenhair fern for continued growth and enjoyment.

Caring for Divided Ferns

After you have successfully divided your maidenhair fern, it’s essential to provide the right care to ensure the separated plants continue to thrive.


When it comes to watering, maidenhair ferns prefer moist soil, but not overly saturated. It’s important to ensure that any excess water can drain away to avoid root rot. Checking the moisture levels of the soil daily and watering it when necessary will help keep the ferns healthy. Keep in mind that potted ferns might need to be watered more frequently than those planted outdoors or placed in terrariums, due to evaporation.


Maidenhair ferns need indirect sunlight, which means placing them near a window with soft, diffused light is ideal. Direct sunlight can scorch their delicate fronds, while insufficient light can result in slow growth or dropping leaves. Remember to rotate your ferns every few weeks so that all sides receive even light exposure.


While maidenhair ferns do not require a lot of fertilizing, they can benefit from occasional feeding. A balanced, water-soluble fertilizer, diluted to half its recommended strength, should suffice. Apply the diluted fertilizer to the divided ferns every 4-6 weeks during the growing season (spring and summer) to provide adequate nutrients for optimal growth.

In summary, caring for divided ferns involves monitoring the moisture levels, providing indirect sunlight, and occasionally fertilizing with a diluted solution. These measures will ensure that your newly divided maidenhair ferns continue to grow and remain healthy.

Common Problems and Solutions

Maidenhair ferns are delicate and beautiful plants, but they can also be prone to certain issues. This section will discuss common problems associated with maidenhair ferns and provide you with the solutions needed to keep your plant healthy.

Yellowing Leaves

One of the main problems that can arise with maidenhair ferns is yellowing leaves. This may indicate a few different things:

  • Overwatering: Too much moisture can lead to yellowing leaves on your maidenhair fern. To address this issue, make sure you are not overwatering your plant, and use room temperature rainwater or spring water when you do water it.
  • Nutrient deficiency: Maidenhair ferns may need additional nutrients, so consider adding a slow-release fertilizer to the potting mix.


Maidenhair ferns sometimes wilt, which can be concerning. Here are some causes and solutions for wilting:
