Macho Fern Care Basics
Caring for a macho fern isn’t difficult but there are a few key things to keep in mind
-
Light: Bright, indirect light is ideal. Avoid direct sun, which can scorch the fronds.
-
Water: Keep the soil consistently moist but not soggy. Allow the top inch of soil to dry out between waterings.
-
Humidity: Mist the fern regularly or use a pebble tray to provide humidity. Ideal levels are 60-70%.
-
Temperature: Average room temperatures between 60-80°F are suitable. Avoid drafty areas.
-
Soil: Use a loose, peaty potting mix. Re-pot in spring if rootbound.
-
Fertilizer: Apply diluted liquid fertilizer every 2-3 months during the growing season.
Providing the Right Growing Conditions
Light Requirements
The macho fern thrives in bright, filtered light. When grown indoors, place it near an east or west-facing window where it will receive gentle morning or afternoon sun. Direct hot sunlight will burn the delicate fronds. Outdoors, situate it in light to medium shade. Dappled sunlight filtering through trees is ideal.
Watering and Humidity
Keep the soil moist at all times, allowing the top 1-2 inches to dry out slightly between waterings. The fronds will become crispy and brown if the plant gets too dry. misting and pebble trays help increase humidity around the fern. Bathrooms provide an ideal humid environment.
Temperature
Average indoor temperatures between 60-80°F suit the macho fern well. Avoid drafty areas as ferns dislike cold drafts. Move the plant outdoors in summer provided nighttime temperatures remain above 50°F.
Soil
Use a loose, peaty potting mix for macho ferns. Amend regular potting soil with peat moss, perlite and orchid bark to improve drainage and aeration. Re-pot in spring if the fern becomes rootbound. Select a pot one size larger and tease apart any circling roots before re-planting.
Fertilizer
Apply a balanced liquid fertilizer at half strength every 2-3 months during the active growing season. Too much fertilizer can burn the roots and foliage.
Growing Indoors vs. Outdoors
The macho fern can be grown both indoors and outdoors in suitable climates. When grown as a houseplant, situate in a bright room with ample humidity. Mist frequently, provide good air circulation and watch for pests like spider mites.
Outdoors, plant in organically rich, acidic soil in light to medium shade. Amend native soil with peat moss or compost to improve drainage. Maintain consistent soil moisture. In areas with heavy winter frosts, grow the fern in a container that can be moved indoors before cold weather arrives.
Propagation
Propagate new macho ferns by division in early spring. Carefully remove the plant from its pot and separate offshoots from the main root ball using a clean knife. Re-plant divisions in small pots using fresh potting mix. Keep the newly divided ferns warm and humid until new growth appears.
Common Problems
-
Leaf tip burn – Caused by dry air, insufficient humidity, or water stress. Improve growing conditions.
-
Leaf drop – Result of overwatering, underwatering, or insufficient light. Adjust care accordingly.
-
Mealybugs & scale – Treat with horticultural oil or insecticidal soap spray.
-
Root rot – Usually caused by overwatering or poorly draining soil. Allow plant to dry out before re-watering.

What is a Macho Fern?
Ferns provide elegant greenery with a classic, airy form. The Macho fern (Nephrolepis biserrata) is one of the best examples of these plants. Best of all, Macho fern care is easy, breezy, and can grow either as a houseplant or an outdoor specimen in warmer regions.
Macho ferns can be found growing wild in Florida, Louisiana, Hawaii, Puerto Rico, and the Virgin Islands. The plant may be epiphytic but is usually found near swamps and wet sites. The big ferns can grow 4 feet (1 m.) tall with fronds that swing out up to 6 feet (2 m.) wide. The stems have fine reddish hairs and the fronds are composed of numerous, gently toothed leaflets.
Also known as the broad sword fern, this fern doesn’t form tubers like some species. In Florida, Macho fern is protected and has experienced population loss due to human intervention. Make sure you get one from a reputable dealer and do not harvest the plant from the wild.
