As loving plant parents, we often go above and beyond to create the perfect environment for our green companions, but when was the last time you thought about the very foundation of your Monstera’s world—its soil?

What if you could create a soil mix that makes your Monstera not just survive, but truly thrive?

Picture your Monstera, its stunning leaves reaching out with gusto, all thanks to the perfect blend of soil that you’ve provided.

Get ready to don your gardening gloves, because we’re about to embark on an underground journey to discover the secret soil mix for hyper Monstera growth.

The Basic Formula

Monsteras hail from the tropical rainforests of Central and South America, where they grow in rich, well-draining soil, which receives a steady supply of organic matter from fallen leaves and other decomposing plant material.

To replicate these conditions at home, the basic formula for Monstera soil should consist of regular potting soil mixed with perlite and peat moss.

If you have these ingredients, your soil mix is off to a good start.

Potting Soil

Potting soil, also known as potting mix, is a medium in which to grow plants, herbs, and vegetables in a pot or other durable container.

High-quality potting soil is usually a blend of several key ingredients, including peat moss or coco coir for moisture retention, vermiculite or perlite for drainage, and compost or other organic matter for necessary nutrients.

Potting soil forms the base of most indoor plant mixes because of its ability to hold moisture and nutrients around the roots, where plants need it the most.

It’s commercially available in various types and blends, depending on your plant’s specific needs.


Perlite originates from volcanic obsidian rock.

When this rock is heated to high temperatures, it expands much like popcorn, becoming a lightweight, porous material.

Perlite for potting mix

This process, known as ‘popping,’ significantly increases its volume, resulting in white fragments that are very light and porous.

Perlite’s key role in potting soil is to enhance aeration and drainage.

Its porous nature allows it to hold 3-4 times its weight in water, yet it does not become soggy.

Its use in your Monstera’s soil mix aids in preventing waterlogging, encouraging root growth, and making it easier for roots to take up nutrients.

Peat Moss

Peat moss is derived from sphagnum moss, a plant that can commonly be found in marshy regions worldwide.

The moss dies and accumulates over thousands of years, forming large deposits known as peat bogs.

Peat moss is then harvested from these bogs, often resulting in environmental concerns about the sustainability of this practice.

Peat moss has an excellent capacity to hold water – it can absorb up to 20 times its weight in moisture, making it a great addition to potting mixtures to prevent soil from drying out too quickly.

It also has a slightly acidic pH, which can help create optimal soil conditions for Monsteras, as these tropical plants prefer slightly acidic to neutral pH levels.

Soil Upgrades You Should Try

For the green-thumbed enthusiasts who enjoy tailoring their own blends, you might want to consider these components:

Orchid Bark or Coco Coir

These components are superb for improving aeration and imitating Monsteras’ natural growing conditions.


Orchid bark is made from the bark of fir trees and is often used in orchid potting mixes due to its excellent drainage and aeration qualities.

This makes it an excellent amendment for those who want to mimic the Monsteras’ native environment more closely.

The irregular shape and size of the bark pieces create air pockets in the soil, promoting healthy root growth.

Coco coir is derived from the husk of coconuts, specifically the coarse fibers on the outer shell.

Like peat moss, it can hold a lot of water, but unlike peat moss, it also offers excellent drainage and doesn’t break down as quickly, meaning it will aerate your potting mix for longer.

Its sustainable sourcing makes it a favorite among eco-conscious gardeners.

Activated Charcoal

Activated charcoal, not to be confused with the charcoal used in barbecues, is a form of carbon that’s been processed to have small, low-volume pores.

These pores increase the surface area available for chemical reactions and adsorption.

In soil mixes, activated charcoal plays an essential role in maintaining soil freshness by filtering out impurities and toxins that can harm plant roots.

It’s especially helpful in containers without drainage holes (like terrariums), but it can benefit any potting mix by improving the soil’s overall health.

Worm Castings

Worm castings, also known as vermicompost, are a type of compost that’s produced by various species of worms feeding on organic waste materials.

This process creates a rich, dark, and crumbly compost that is packed with nutrients.

Worm castings release these nutrients slowly, meaning they will provide a steady supply of nutrients to your Monstera over time.

They also improve the soil’s structure, increase its water-holding capacity, and can even help suppress diseases and harmful pests.

The Ideal Soil Composition

Incorporating these elements, your Monstera soil mix could look like this: 40% potting soil, 20% perlite, 10% peat moss, 20% orchid bark or coco coir, 5% activated charcoal, and 5% worm castings.

This mix not only provides the basic necessities for your Monstera’s growth but also enhances the soil’s structure, nutrient content, and overall health, creating a habitat in which your Monstera can truly thrive.

It is also important to note that the extraction of peat moss can be harmful to the environment as it contributes to greenhouse gas emissions and destroys the habitats of some wildlife.

If this is a concern, consider using a more sustainable alternative like coco coir, which has similar properties to peat moss but is a byproduct of the coconut industry.
