Boston Fern vs Fern Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Boston Fern
Nephrolepis exaltata
The Boston Fern is a classic houseplant known for its graceful, arching fronds. It's a terrestrial fern, naturally found in humid forests and swamps. Its lush green foliage creates a soft, textured appearance, making it a popular choice for adding a touch of nature to indoor spaces. People grow it for its aesthetic appeal, air-purifying qualities (though not definitively proven by NASA), and relatively easy care, provided its humidity needs are met. It is primarily an outdoor plant but can adapt to indoor conditions with proper care.
Fern
Nephrolepis exaltata
The Boston Fern is a classic houseplant known for its graceful, arching fronds. It's an evergreen perennial that thrives in humid environments. The fronds are composed of numerous small, sword-shaped leaflets (pinnae) giving it a lush, feathery appearance. While naturally an outdoor plant in tropical and subtropical climates, it's widely grown indoors for its air-purifying qualities and aesthetic appeal. It adds a touch of natural elegance to any space, making it a popular choice for homes and offices.

❓ Frequently Asked Questions — Comparing These Plants
Boston Fern
What are the light requirements for Boston Fern?
Boston Ferns prefer bright, indirect light. Direct sunlight can scorch the delicate fronds, causing them to turn brown and crispy. An east-facing window is ideal, providing gentle morning sunlight. A north-facing window can also work, but the plant may not grow as vigorously. If placing the fern near a south- or west-facing window, be sure to filter the light with a sheer curtain. Insufficient light can lead to leggy growth and pale fronds. Rotate the plant regularly to ensure even light exposure on all sides. Artificial grow lights can supplement natural light, especially during the darker winter months.
How do I care for Boston Fern?
Boston Ferns thrive in bright, indirect light and high humidity. Water consistently, keeping the soil evenly moist but not soggy. Check the soil moisture regularly and water when the top inch feels slightly dry. Mist the fronds frequently or place the plant on a pebble tray filled with water to increase humidity. Fertilize monthly during the growing season (spring and summer) with a diluted liquid fertilizer formulated for ferns. Avoid placing the plant in direct sunlight or near drafts, as these can cause the fronds to dry out and turn brown. Repot every 1-2 years in the spring, using a well-draining potting mix. Regularly remove any dead or yellowing fronds to encourage new growth and maintain the plant’s appearance. Monitor for pests such as spider mites and treat as needed.
How do I propagate Boston Fern?
Boston Ferns can be propagated by division or by spores. Division is the easier method. To divide, carefully remove the plant from its pot and gently separate the root ball into two or more sections, ensuring each section has healthy fronds and roots. Repot each section in fresh potting mix. Propagation by spores is more challenging. Collect spores from the underside of mature fronds and sow them on a moist, sterile potting mix. Cover with a clear plastic dome to maintain high humidity and keep in indirect light. Spores can take several weeks or months to germinate. Keep the soil consistently moist and provide adequate ventilation to prevent fungal growth.
Fern
What are the light requirements for Fern?
Ferns prefer bright, indirect light. Direct sunlight can scorch their delicate fronds, causing them to turn brown and crispy. An east-facing window is often ideal, providing gentle morning light. A north-facing window can also work if the light is bright enough. If placed near a south or west-facing window, use a sheer curtain to filter the light. Insufficient light can lead to leggy growth and pale fronds. Observe your fern carefully; if the fronds appear faded or are growing slowly, it may need more light. Rotate the plant regularly to ensure even light exposure on all sides. Artificial light can also supplement natural light, especially during the darker winter months. Fluorescent or LED grow lights are effective options, placed about 12-18 inches above the plant.
How do I care for Fern?
Ferns require consistent moisture and high humidity to thrive. Water thoroughly when the top inch of soil feels dry, ensuring good drainage to prevent root rot. Maintain humidity levels above 60% by misting regularly, using a humidifier, or placing the fern on a pebble tray filled with water. Provide bright, indirect light, avoiding direct sunlight which can scorch the fronds. Use a well-draining potting mix rich in organic matter. Fertilize monthly during the growing season (spring and summer) with a balanced liquid fertilizer diluted to half strength. Repot annually in the spring, selecting a pot only slightly larger than the previous one. Remove any dead or yellowing fronds to encourage new growth. Protect ferns from drafts and sudden temperature changes. Monitor for pests such as spider mites and scale, and treat promptly with insecticidal soap or neem oil. Pruning is generally not necessary, but trimming away damaged fronds can improve the plant’s appearance.
How do I propagate Fern?
Ferns can be propagated through division or by spores. Division is best done in the spring during repotting. Carefully separate the root ball into two or more sections, ensuring each section has healthy fronds and roots. Plant each section in its own pot with fresh potting mix. Keep the soil consistently moist and provide high humidity. Spore propagation is more challenging. Collect spores from mature fronds and sow them on a moist, sterile growing medium. Cover with a humidity dome or plastic bag and keep in a warm, shaded location. Spores require consistently high humidity and can take several weeks or months to germinate. Once the spores have germinated and formed small plantlets, gradually acclimate them to lower humidity levels. Transplant the plantlets into individual pots when they are large enough to handle.
