Division Propagation Method

If you’re looking for a quicker way to expand your Boston Fern collection, division propagation is a great option. This method involves dividing a mature fern into multiple plants, allowing for faster growth and expansion.
To begin the division propagation process, follow these simple steps:
- Choose a mature Boston Fern that is ready for division. Look for a plant with multiple crowns or clumps.
- Remove the fern from its pot and gently shake off excess soil.
- Locate natural divisions or separate the clumps into smaller sections. Each section should have at least two to three crowns.
- Use a clean, sharp knife or garden shears to carefully cut through the rootball and separate the sections.
- Ensure each divided section has healthy roots and foliage.
- Prepare individual pots with well-draining soil mix.
- Plant each divided section in a separate pot, ensuring the crowns are slightly above the soil surface.
- Water the newly divided ferns thoroughly and place them in a location with bright, indirect light.
- Maintain consistent moisture levels by watering whenever the top inch of soil feels dry.
- Monitor the growth of your newly divided ferns and provide appropriate care as they establish themselves.
Root Division Propagation Method

If you’re looking for another effective method to propagate your Boston Fern, root division is a great option. This technique involves separating and replanting the existing root system to create new plants. It’s a straightforward process that can yield multiple thriving ferns.
To propagate your Boston Fern through root division, follow these simple steps:
- Start by carefully removing the fern from its pot, gently shaking off any excess soil.
- Inspect the root system to identify the natural divisions where you can separate the plant into sections. Look for areas where the roots naturally come apart.
- Using clean and sharp scissors or a knife, divide the root system into separate sections, making sure you have enough roots attached to each division. Aim for at least a few fronds per division to ensure healthy growth.
- Prepare separate pots or containers with well-draining soil and make small holes for each divided section.
- Place each division into its designated pot, making sure the roots are spread out and covered with soil. Gently firm the soil around the roots to provide stability.
- Water the newly potted divisions thoroughly, allowing the soil to become evenly moist. Avoid overwatering as excessive moisture can lead to root rot.
- Find a suitable location for your new ferns, ensuring they receive proper indirect light and adequate humidity. Boston Ferns thrive in bright but indirect light conditions.
- Monitor the moisture level in the soil and water the plants when the top inch of soil feels dry. Aim to maintain consistent moisture without waterlogging the plants.
