This method of propagation is best done during the active growth period of the fern, which is typically in spring or early summer.
Propagation Through Layering Runners
- Identify the runners, also known as stolons, that extend from the parent plant.
- Affix the runners to the soil or a potting medium in separate containers, ensuring that a portion of the runner is covered with soil.
- Keep the soil or potting medium consistently moist to encourage root development.
- Once the runners have taken root and developed new fronds, they can be detached from the parent plant and transplanted into their own containers.
Propagation through layering runners can be done at any time of the year.
How to Grow Boston Ferns
Boston ferns are beautiful and resilient plants that can add a touch of lush greenery to your indoor space. To ensure their optimal growth and health, it’s important to provide them with the right conditions and care. Here are some essential tips for growing Boston ferns:
- Choose the right soil: Boston ferns thrive in well-drained, moisture-retaining soil. Use a high-quality potting mix that provides good drainage to prevent waterlogged roots.
- Provide indirect sunlight: Boston ferns prefer indirect sunlight or dappled shade. Place them near a window where they can receive bright but filtered light. Avoid placing them in direct sunlight, as it can scorch the delicate fronds.

- Fertilize during active growth: During the growing season, fertilize Boston ferns every two weeks with a balanced liquid fertilizer diluted to half strength. This will provide the necessary nutrients for healthy foliage development.
Maintenance of Boston Ferns
Proper maintenance is essential for the health and vitality of your Boston ferns. Regular care, including pruning and dividing, will ensure that your ferns continue to thrive and beautify your indoor space.
Removing Older or Dying Fronds
As your Boston fern grows, it’s natural for older fronds to start deteriorating. To maintain a neat and tidy appearance, gently remove these older or dying fronds from the plant. Use clean scissors or garden shears to cut them back, making sure to avoid damaging the healthy foliage.
Dividing the Plant
Dividing your Boston fern every few years helps prevent overcrowding and allows the plant to continue growing vigorously. To divide your fern, carefully remove it from its container and gently separate the root ball into smaller sections. Transplant each section into its own appropriately-sized container, using a well-draining potting mix.
Monthly Fertilization During Active Growth
During the active growth period, typically during spring and summer, your Boston fern will benefit from monthly fertilization. Choose a balanced liquid or slow-release fertilizer specifically formulated for ferns. Follow the dosage instructions provided to avoid over-fertilization, which can harm the plant.
Reduced Fertilization During Winter Dormancy
When your Boston fern enters its winter dormancy phase, reduce the frequency of fertilization. During this time, the plant’s growth slows down, and it requires less nutrients. Fertilize your fern every two to three months, following the dosage instructions for reduced application rates.
Promoting New Growth through Trimming
If your Boston fern starts to look unruly or ratty, don’t fret! Trimming back the plant can encourage new growth and help maintain its overall appearance. Use clean scissors to trim away any damaged or disheveled fronds, encouraging the plant to produce fresh, vibrant foliage.

Managing Pests and Diseases of Boston Ferns
While caring for Boston ferns, it is important to be aware of potential pests and diseases that can affect their health and beauty. Although Boston ferns are generally resilient, they can still fall prey to insect infestations and certain diseases, especially when grown outdoors.
Common Pests:
- Spider Mites: These tiny pests can cause damage by sucking sap from the fronds, resulting in yellowing and wilting of leaves. Regularly inspect your Boston ferns for spider mites and take immediate action if detected.
- Mealybugs: Mealybugs are another common pest that can infest Boston ferns. These small, fuzzy insects suck sap from the plant and leave behind a sticky residue. Inspect the fronds and stems for signs of mealybug infestation and take necessary steps to control them.
Pest Control Measures:
- Regular Inspection: To prevent severe infestations, regularly inspect the foliage, both on the upper and lower sides of fronds. Keep an eye out for signs of pests such as webbing, white clusters, or sticky residue.
- Natural Remedies: For mild infestations, consider using natural pest control methods such as spraying the foliage with a mixture of water and neem oil or wiping the leaves with soapy water.
- Chemical Control: If the infestation persists or becomes severe, you may need to resort to chemical control methods. Choose an appropriate insecticide labeled for use on ferns and follow the instructions carefully.
Preventing Diseases:
- Maintain Good Air Circulation: Proper air circulation helps prevent fungal diseases such as root rot. Avoid overcrowding your Boston ferns and provide enough space between plants.
- Avoid Overwatering: Overwatering can lead to fungal diseases and root rot. Allow the soil to dry slightly between waterings and ensure that the pots have drainage holes.
- Cleanliness: Remove any dead or decaying leaves promptly. This will prevent the spread of fungal spores and the development of diseases.
