How to Split a Fern: A StepbyStep Guide for Successful Propagation

How to Split a Fern?

To split a fern, you will need to dig it out of the ground or remove it from its pot.

The best time to divide the fern is in the spring if it is indoors, or in the fall or early spring if it is outdoors.

Once the fern has been removed, rinse the soil from its roots.

Then, separate the roots into two sections by either pulling or cutting them apart.

Immediately repot or plant the new divisions, and water them generously.

To provide sufficient moisture, mist the new divisions every morning for a month.

If the fern has rhizomatous roots, additional tips should be followed.

Key Points:

  • Dig out or remove fern from ground or pot to split it.
  • Best time to divide fern is in spring (indoors) or fall/early spring (outdoors).
  • Rinse soil from fern’s roots after removing.
  • Separate roots into two sections by pulling or cutting.
  • Immediately repot or plant new divisions and water generously.
  • Mist new divisions every morning for a month to provide sufficient moisture.


Did You Know?

1. Did you know that splitting a fern is actually a form of asexual reproduction? Each part you separate from the original fern can develop into a whole new plant, creating an identical genetic clone!
2. While ferns reproduce through spores, splitting them is a faster and more efficient way to propagate them. With the right care, a split fern can start growing within a few weeks!
3. Many ferns have been around since prehistoric times and coexisted with the dinosaurs. By splitting a fern, you are continuing a botanical lineage that has survived for millions of years!
4. Splitting a fern is not just for propagation purposes, but also for maintenance. As ferns grow and spread, dividing them can help control their size and prevent overcrowding.
5. Some cultures believe that ferns possess protective qualities and can ward off evil spirits. Splitting a fern is believed to increase its power and bring good luck to the person tending to it.

Digging The Fern Out

When splitting a fern, follow these steps:

  1. Remove the fern carefully from the ground or its pot. If it’s planted in the garden, use a small garden spade or trowel to dig around the base of the plant, being cautious not to damage the delicate roots.
  2. Lift the fern gently from the ground, making sure to retain as much of the root system as possible.
  3. If the fern is potted, carefully slide it out of the container, being mindful not to break the pot or disturb the root ball.

Dividing The Fern In The Spring Or Fall

The ideal times to divide a fern are in the spring if it is potted indoors, or in the fall or early spring if it is planted outdoors. This is when the fern is actively growing, allowing it to quickly recover and establish new root systems. Divide the fern by carefully separating the individual fronds or by dividing the clump of roots. If dividing by fronds, make sure each section has a healthy amount of foliage and a portion of the root system. If dividing by root clumps, gently pull or use a clean knife or shears to cut the roots apart, ensuring that each division has an adequate root system.

Rinsing The Soil From The Roots

After dividing the fern, it is crucial to rinse the soil from the roots. This allows for a better examination of the root structure and ensures that the plant will be able to absorb nutrients and water effectively in its new environment.

To rinse the roots, gently place the fern under a gentle stream of lukewarm water or immerse it in a container of water. Gently swish the fern around to dislodge the soil, taking care not to damage the delicate roots. Continue rinsing until the roots are clean and free of any remaining soil particles.

Separating The Roots Into Two Sections

Once the soil has been rinsed from the roots, the next step is to separate the roots into two sections. Depending on the size and health of the fern, this can be done by pulling the roots apart by hand or by using clean gardening shears or a knife to cut the roots in half. Make sure to divide the roots evenly, ensuring that each section has enough healthy roots to support the growth of the plant.

  • Rinse soil from the roots
  • Separate roots into two sections
  • Pull apart by hand or use clean gardening shears or a knife to cut
  • Divide roots evenly
  • Ensure each section has enough healthy roots to support growth

Repotting Or Planting Immediately

After separating the roots, it is important to repot or plant the divided fern sections immediately. Here’s how to do it effectively:

  • Choose a suitable container or planting location that provides adequate drainage and enough space for the fern to grow.
  • Gently position the roots in the soil, ensuring they are well spread out and covered with soil.
  • For potted ferns, use a high-quality potting mix to provide the necessary nutrients.
  • For outdoor planting, loosen the soil and add organic matter to improve drainage.
  • Water the fern generously after potting or planting to settle the soil and ensure the roots have access to moisture.

Remember, immediate action and proper care are crucial for the successful growth of divided fern sections.

Mist The New Divisions Daily For A Month.

To maintain a humid environment and provide sufficient water for new divisions of a fern, it is recommended to mist them daily for at least a month. This helps prevent dehydration and promotes healthy growth.

Here are the steps to follow:

  1. Fill a clean spray bottle with water.
  2. Gently mist the foliage of the fern, making sure to evenly distribute the water without soaking or damaging the delicate leaves.
  3. It is best to mist in the morning, allowing excess moisture to evaporate throughout the day.
  4. Continue misting daily for a month until the fern is well established.
  5. After a month, the fern should no longer require daily misting.

Remember to be gentle and patient throughout the process, ensuring that each division has enough roots and foliage to thrive in its new environment.

Frequently Asked Questions

Can you split up a fern?

Splitting up a fern can be a delicate process due to its tightly intertwined root system. To begin, carefully remove the fern from its current pot or dig up the clump, being cautious not to damage the roots. Afterward, gently brush off and shake loose any excess soil. Although ferns have compact root balls, a long serrated knife can be used to make precise cuts, dividing the root ball into halves or quarters. The careful division of the root ball allows for the creation of new fern plants, each with a portion of the original root system.

Can ferns be propagated by cuttings?

Yes, ferns can indeed be propagated by cuttings. While division and propagating from spores are also common methods, taking leaf clippings is another effective way to propagate ferns. By carefully removing a healthy leaf from the parent plant and placing it in a suitable growing medium, roots can develop from the leaf’s base, leading to the growth of a new fern plant. This method allows for the creation of multiple ferns from a single parent plant, making it a convenient and efficient way to expand your fern collection.

How do you divide a button fern?

One effective method to divide a button fern is during the process of re-potting. By utilizing a sharp sterilized knife, you can cautiously slice the root ball in half, subsequently separating the plant into two distinct sections. Ensure each division is then planted in its individual pot, allowing them to develop independently and flourish in their new environments. This division strategy not only promotes the growth of the button fern but also enables you to easily propagate and expand your collection of these elegant plants.

Can sword ferns be divided?

Yes, sword ferns can be divided. The most effective way to propagate these ferns is by dividing the rhizomes, as the spores are tiny and intricate to handle. The ideal period for dividing a western sword fern is in early spring, before the plant has completely sprouted. During this time, the plant is more receptive to division, enabling successful propagation.
