Macho Fern Care — The Complete Guide

Macho Fern Care — The Complete Guide

Sharing is caring!


Nephrolepis biserrata, more commonly known as the Macho fern, is one of the most popular houseplants today. Having massive, burly foliage, the Macho fern earns its name due to the space it occupies and its bold but graceful look. 

An excellent way to describe the Macho fern is just two words – “Pure Beauty.” These plants are grown worldwide as decorative houseplants. They can be seen adorning porches, patios, shaded garden spaces, and even indoor spaces. 

Although caring for this plant is not a very tricky task, it does have a few requirements that a Macho fern parent must know about. 


Macho Fern Care

Good soil drainage and aeration are a must for Macho ferns. It will thrive in shaded or partially shaded locations. Bright indirect light for 4-6 hours a day is needed. Water this plant every time the top layer of the soil dries out. The ideal growing temperatures for the fern are 50-80°F (10-26°C).



The Macho fern plant thrives in well-draining, loamy or sandy soil. The soil should have a good water retention factor as the plant does not like to be left without water for a long time. This plant will love soil that is rich in organic matter and prefers it slightly on the acidic side (pH 6-6.5).

In nature, the Macho fern can be spotted growing in locations with varying atmospheric and soil conditions. From around ponds and swamps to rock crevices, this plant can grow anywhere. 

It can also be found growing as an epiphyte on bigger plants. This tells us that the beautiful Macho fern is well suited to a range of soil types, be it sandy, loamy or rocky. 

Although it’s not very picky about the soil type, this plant will not do well in waterlogged soils. Good soil aeration and drainage are a must. The plant’s health will quickly deteriorate if the soil does not have these characteristics. 

Nephrolepis biserrata usually grows on the forest floor under the dappled shade of the forest canopy. Forest floors are naturally rich in organic matter, which helps the fern to thrive. 

Only use well-aerated and well-draining soil when planting a Macho fern in your garden or in a pot. 

If you think your garden soil is too heavy, you can add a combination of potting media such as organic compost, perlite, and coco peat to make the soil lighter. 

Use these to fill the hole before placing the root ball inside, and then fill it up on all sides of the Macho fern. 

When growing this plant in a pot, you can use the recommended houseplant potting mix for your Macho fern. To customize the mixture to a fern’s liking, add up on the organic content to enhance fertility, soil drainage, and water retention. 



The Macho fern does not need a lot of sun. It will thrive in shaded or partially shaded locations. Bright indirect light for 4-6 hours a day is more than enough. Protect this plant from direct sunlight as it can burn the foliage. Mild morning or afternoon sunlight will serve the fern well. 

One thing that makes the Macho fern a perfect houseplant is its required light levels. It will do well in any shaded place, and you will not have to worry about the plant not getting enough light.

Outdoors, these plants cannot be grown in open, unshaded spaces as staying in direct sunlight for extended periods will definitely kill them.

They are best grown next to walls that provide shade during the hottest part of the day or under trees. A linear Macho fern plantation looks really good when planted alternatively to a linear tree plantation. 

If you’re growing a Macho fern in planters, they can be easily grown on your porch or patio in the summer. The bright indirect light in these locations is ideal for this plant. 

If you have to bring your fern indoors for the winter, bear in mind that not to place it somewhere too dark for its liking. 

Make sure it gets bright indirect light by placing it next to a North or East facing window. 



The Macho fern requires water in moderation. It does not like to be left thirsty for a long time and will thrive if its soil is kept consistently moist. Water this plant every time the top layer of the soil dries out. Do not water heavily, but only to make the soil moist and not soggy. 

If there is one department of Macho fern care that can seem like the most demanding one, it is the watering requirements. 

Macho ferns like a consistent supply of moisture but will not tolerate excessive moisture. The key to watering this tropical plant is to keep supplying small amounts of water with short intervals in between.  

Usually, we water our houseplants heavily once most of the soil has dried out. We cannot follow the same watering practice with a fern. 

You cannot allow the soil to fully dry out, neither water the plant heavily that the water sits in the pot for a long time. 

You can make caring for a Macho fern, especially the watering, easy for you by using water-retaining soil. 

Using highly organic soil or by adding water-retaining ingredients to the soil, you reduce the risks of overwatering and even underwatering your plant. 

If your Macho fern is suffering from a lack of soil moisture, the foliage begins to lose its coloring and starts shedding leaves. 



Macho ferns are tropical plants and prefer warmer temperatures. They are also tolerant to relatively low temperatures when compared to other houseplants. The ideal growing temperatures are 50-80°F (10-26°C). It is well-suited to USDA Hardiness zones 9-10. 

Macho ferns are naturally found on tropical forest floors, a highly protected environment with temperatures between a highly regulated range. 

They like temperatures on the warmer side but will suffer if the mercury rises too high or dips too low. 

Macho ferns cannot tolerate temperatures below the freezing point, neither will they like temperatures above 95°F (35°C). 

If you live in cooler climates, you will have to overwinter your Macho fern indoors or in a protected greenhouse environment. 



Optimum humidity levels are critical for a Macho fern to thrive. All tropical plants love humid conditions, but ferns, in particular, need high humidity to grow lush, healthy foliage. A Macho fern typically enjoys humidity levels higher than 70% in its native habitat.

Due to their high humidity preference, Macho ferns are the perfect plant to grow in bathrooms. 

Given there is adequate natural light in your bathroom, you can fill the whole place with Macho ferns to enjoy the humidity, and for you to fill every space, there is in your home with plants. 

In typical indoor environments, especially in the winters, humidity levels are too low, and tropical plants such as the Macho fern are prone to suffer. 

To notch up on the humidity levels for your plant, you can use a pebble tray filled with water. Using a humidifier is also a good idea if you have more plants that need high humidity. 

Misting your Macho fern is an option, but it can often lead to fungus-related problems if the water stays on the foliage for too long in warm and dark conditions. 



Fertilizing your Macho fern is not a must, as this plant will do equally well otherwise. The organic matter present in the soil is more than enough. Once in a while, fertilization with an all-purpose formula will ensure healthy and vibrant foliage.

Overfertilization is a danger you want to avoid at all costs. You can damage half or more than half of your healthy Macho fern just by adding a bit too much fertilizer. 

Water your plant before you add fertilizer to avoid root tip burn and reduce the risk of over-fertilizing your plant.



Mature Macho fern plants can grow as wide as 6 feet and 4 feet in height. Each frond can grow 3-4 feet in length with bold and broad, gently toothed leaves. The stems have very thin, reddish hair on their surface. 

The Macho fern is considered a threatened species in the USA because of the rapid loss of its natural habitat. 

It is a great ground cover because of its spreading ability and can also do well in vertical plantation styles. 

The fronds of a Macho fern spring out from the core of the plant in different directions, giving a bold, jazzy look. 

The foliage looks deep green at the base of each leaf and turns light green at the tips. 



Macho ferns grow best in large containers or hanging baskets at least 8-10 inches in diameter. This plant will keep growing laterally, and you will need a bigger pot every subsequent year. Terra cotta pots are recommended because the soil stays well-aerated in them. 

Macho ferns need macho pots. This tropical plant will not grow for long in a small pot and will keep demanding more and more growing space with every growing season. 

Using terra cotta pots is a good choice for Macho ferns because this material prevents the risk of root rot. 



Although Macho ferns are rapid growers and can outgrow their space quickly, pruning is not a necessary part of Macho fern care. It is recommended to remove dead fronds and also highly damaged fronds to encourage new, healthier growth. 

You can prune your Macho fern from the edges to prune it to a round or cloud shape. You can also remove crisscrossing stems to give the plant a tidier look. 


Macho Fern Propagation

Macho ferns are propagated by the division method. New root clumps can be separated from the root ball and planted in separate pots. Ferns do not produce seeds, so they can’t be propagated this way. 

If you find your Macho fern has grown new stems and its pot is getting smaller, you can take out the rootball and separate the new root clumps on the sides of the central root cluster. 

The new root clumps can easily be potted in a new pot with houseplant potting mix and placed in a warm and protected environment to get established.

Covering the repotted clumps with a clear plastic bag mimics greenhouse conditions, prevents the plants from drying out, and helps them get established quickly.  

The newly divided Macho fern plants will not seem as healthy or bushy at first but will grow healthy foliage after some time.

Common Problems with Macho Ferns

The Macho fern is a low-fuss plant and does not require a lot of attention. But when the right conditions are not provided, it can suffer from a few common diseases and pests.


Leaf Tip Burn

The leaf tips of a Macho fern can easily dry out due to a range of reasons which include but are not limited to overwatering, excessive sunlight, and low humidity. 

There is no way of going around this problem except removing the root cause after identifying it. When conditions are right, the plant will grow new and healthy foliage on its own. 



Nematodes are underground pests that damage the plant’s roots and eventually lead the plant to wilt and die. 

They are usually found in mulched soil and are very hard to eliminate. Remove any soil mulches and dead plant matter from the soil to prevent a nematode invasion.



Macho ferns are an excellent houseplant for the beginner plant parent. If a novice plant grower can get Macho fern plant care right, they get a lifelong plant friend and much-needed experience they need to grow more houseplants at their place.
