Macho Fern
Nephrolepis biserrata 'Macho'
The Macho Fern is a gargantuan and vigorous fern that serves as a spectacular focal point in any indoor or outdoor shaded space. Featuring broad, leathery, sword-shaped fronds that can arch gracefully up to 6 feet long, it is significantly larger and more resilient than the standard Boston Fern. It is a true tropical giant that brings a lush, ancient aesthetic to home decor.

Care Guide
Macho Fern Care Guide
Light
Prefers bright, filtered light. While it can tolerate some shade, prolonged direct afternoon sunlight will scorch the fronds. A north or east-facing window is often ideal.
Water
Keep the soil consistently moist. This fern does not tolerate drying out; if the soil becomes too dry, the plant will shed leaflets. Water when the surface of the soil just begins to feel slightly dry.
Humidity
Humidity is crucial. Maintain levels above 50-60%. Use a humidifier, mist the plant frequently, or place it on a pebble tray. It is an excellent choice for a large, bright bathroom.
Soil & Potting
Use a rich, peat-based potting mix that retains moisture while allowing for adequate drainage. Repot every 1-2 years as the plant becomes root-bound.
Seasonal Tips
In winter, growth will slow. Reduce watering frequency slightly and stop fertilizing, but ensure humidity remains high as indoor heating can be very drying.
Common Issues
Yellowing Fronds: Usually a sign of overwatering or poor drainage. Brown Tips: Typically caused by low humidity or hard water minerals.
