By | Updated October 3, 2023

Monstera aerial roots grow from the stem above the ground, providing support and absorbing moisture. Keeping them healthy benefits the plant’s overall health, and they can be used for support. They can also be trimmed if they are too long or unsightly.

Monstera, more commonly known as the Swiss cheese plant, is an evergreen climbing vine that has become hugely popular in recent years due to its striking foliage and easy-care requirements.

The leaf of the evergreen climbing vine has become a popular feature in many gardens, with its glossy, deep green foliage providing a stunning backdrop to any outdoor space and requiring minimal care to keep it looking lush and healthy. 

But did you know that this tropical plant also produces aerial roots?

These unique root systems are a fascinating feature of Monsteras. They allow them to climb trees and other structures in their natural habitat.

In this article, we’ll delve into what aerial roots are, what can you do with them, and how you should care for them.

What Are Monstera Aerial Roots?

Monstera plant’s aerial roots are a type of root that grows above the ground level. They are also known as air roots or adventitious roots.

Unlike underground roots, or subterranean roots, that grow in soil, aerial roots absorb moisture from the air.

These Monstera roots can be found in many different plant species, including Monstera plants.

Monstera aerial roots typically start as small knobs that grow out of the plant’s nodes.

Over time, they can reach several feet long and become thick and woody. These roots have a rough texture and are usually brown in color.

Why Monstera Plants Grow Aerial Roots

Monstera plants grow aerial roots for several purposes.

One primary function of these roots is to provide structural support for the plant as it climbs. In nature, Monstera plants utilize their aerial roots to attach to tree trunks, providing stability and enabling them to reach higher for better exposure to light.

Another significant role of Monstera’s aerial roots is to absorb moisture from the air. In the plant’s native tropical habitats where humidity levels are high, aerial roots allow Monstera plants to extract moisture, supplementing their water intake.

Additionally, aerial roots aid in anchoring the plant within its growing medium. When cultivated in potting mix or other substrates, these roots play a vital role in maintaining the plant’s stability and preventing it from toppling over.

Aerial roots are a crucial aspect of the growth strategy for these distinctive plants. Monstera vines use these roots to attach themselves to nearby structures like trees, walls, or poles, providing support and stability for climbing and spreading. This allows the plant to access more sunlight and nutrients, promoting optimal growth and vitality.

Understanding the purposes of these specialized roots helps in providing appropriate care for your Monstera plant and fosters a deeper appreciation for its beauty in all its aspects.

What To Do With Aerial Roots

Monsteras aerial roots are an interesting and sometimes confusing feature of this popular houseplant.

These dangling, hairy-looking appendages can be intimidating for first-time Monstera owners, but don’t worry; there’s nothing to be afraid of!

In fact, with a bit of knowledge and understanding, you can help your plant thrive.

Here are some things you can do with Monstera aerial roots to make the most of this unusual but beneficial feature.

Leaving the Roots Alone

The first, and often simplest, way to deal with Monstera aerial roots is to leave them alone.

These types of roots naturally grow outwards and downwards, so as long as they’re not causing any damage or blocking sunlight from other parts of your plant, there’s no need to do anything.

Your Monstera can use its aerial roots to climb to brighter light, absorb moisture from the air, and anchor itself into its growing medium.

Simply let them do their job and enjoy watching your plant thrive!

If you choose to leave the aerial roots as is, there are a few things you can do to make them look more aesthetically pleasing.

One option is to wrap them around a moss pole or other support structure. This will make the plant look more attractive and provide additional support for the stems and leaves.

Another option is to trim any dead or damaged portions of the aerial roots. This will help keep your plant healthy and prevent any potential issues from arising.

It’s important to note that while leaving aerial roots intact may benefit your vining plant, it’s not always necessary.

If you prefer a neater appearance or don’t have a support structure for your plant to climb on, it’s perfectly fine to trim away any excess growth.

Trimming Back Aerial Roots

If you’re dealing with Monstera aerial roots that are starting to take over your plant or just don’t fit with your aesthetic preferences, trimming them back is a simple solution.

But before you start snipping away, there are a few things you should know.

It’s important to understand that cutting off aerial roots will not harm the plant.

In fact, these roots will often grow back quickly after being trimmed. So if you’re worried about damaging your beloved Monstera, rest assured that it can handle a little pruning.

How To Trim Them Back

To trim back unsightly or overgrown aerial roots on your Monstera plant, you’ll need a sharp pair of pruning shears or scissors.

Ensure they’re clean and sterile to prevent any potential infections in the plant.

When cutting back aerial roots, it’s best to make clean cuts as close to the main stem as possible without damaging it.

This will help promote healthy regrowth and prevent any damage to the rest of the plant.

Once you’re done trimming, remove any excess leaves or debris to keep the area clean and tidy.

It’s also a good idea to mist your plant with water afterward, as this will help keep it hydrated during the healing process.

Training Aerial Roots

Training Monstera aerial roots is a great way to keep your plant tidy while allowing it to use these appendages for support and hydration.

The primary purpose of these roots is to allow the plant to climb and provide structural support.

Can You Use Aerial Roots for Propagation?

Are you wondering if you can propagate Monstera aerial roots?

Well, the short answer is no. Aerial roots alone cannot be used for propagation. This is because aerial roots are not designed to spread in the same way that plantlets or stem cuttings can.

Aerial roots form a natural part of the Monstera life cycle and serve many purposes, such as assisting with climbing and moisture absorption.

These roots are not suitable for producing new plants alone, although they can be used in conjunction with other methods to encourage growth.

Propagation requires a piece of the stem that includes at least one node and one aerial root.

The node is where new growth will emerge, and the aerial roots will help anchor the Monstera cutting in soil or water.

But don’t worry! If you have a Monstera plant with aerial roots, it’s still possible to propagate it using stem cuttings.

Monstera Propagation Methods

When propagating Monstera, there are three main methods to choose from: water propagation, soil propagation, and air layering.

Water Propagation

Water propagation is a popular method for propagating Monstera plants.

To do this, place your stem cutting in filtered water, submerging the node and aerial root.

Change the water every few days to keep it fresh and prevent bacteria growth.

After several weeks, you should start to see roots forming from the node and possibly even new leaves emerging.

Soil Propagation

Soil propagation is another option for propagating your Monstera plant from a cutting.

To do this, prepare a pot with well-draining soil and insert your stem cutting into the soil to cover the node and aerial root.

Water thoroughly and keep the soil moist but not waterlogged. Place your pot in bright indirect light and wait for new growth to emerge.

Air Layering

Air layering is another technique for propagating Monstera plants that involves encouraging roots to form while still attached to the parent plant before separating them as an independent plant.

To do this, locate a stem at least 8 inches long and gently remove a quarter-inch of bark from the section you wish to propagate.

Then, wrap sphagnum moss around the area and secure it with plastic wrap. After several weeks, roots should form in the moss, and your cutting can be detached from the parent plant.

Final Thoughts

Houseplants, such as Monstera, are becoming increasingly popular due to their intriguing features, like aerial roots, making them a great addition to any home. They provide a unique and eye-catching display that is sure to liven up any living space.

While not necessary for a healthy Monstera, aerial roots can provide support, stability, and aid in moisture absorption.

Vining plants like Monstera are an excellent way to add a touch of greenery to your home. They can be trained to climb up walls and trellises, creating a lush and vibrant atmosphere that can be enjoyed for years to come.

If you choose to keep your Monstera outdoors, you can take advantage of natural sunlight and fresh air to help it thrive.

You’ll also enjoy the beauty of your plant in its natural environment and the satisfaction of watching it grow and flourish in the great outdoors.

Ultimately, the decision to use aerial roots or not is yours. Either way, you’ll have a stunning plant to admire.

Happy growing!
