Taking care of your plants: Soil for aroids

@photo from Amazon

Are you a plant addict and taking care of your plants is a bit like taking care of your own children?

You are in the right place!

Here are some tips to help you!

The most important thing is to know your plant and its needs, but also know your watering routine and in what conditions your plant will grow: light, temperature, humidity are very important factors.

Because each interior and maintenance conditions are different,

Because everyone waters differently,

Because there are 1001 ways to grow your plants in different substrates,

Because sometimes you want something simple and effective for the majority

of your plants.

Do I want to water often?

Is my interior humid?

Will my plants have light?

Here is a way of doing things, among many other options, that is effective for the majority of aroids, and that forgives watering errors!

The most important thing is to understand the purpose of each ingredient, as some can

be substituted by others.

The goal of a good substrate is good aeration, good water retention, while allowing nutrients to be transported correctly.

In fact, the roots will be able to draw everything they need from the substrate in order to support the health of the plant by making it grow and flourish.

Good drainage allows effective drying of the substrate to prevent water

does not stagnate in it and can maintain good humidity: this helps prevent the appearance of rot at the roots.

Once the ingredients and their usefulness are well understood, this will allow you to adapt

your substrate to your reality.

For example: a heavy hand on watering and a very humid place could drastically affect the drying time of your substrate, it will be up to you to gauge the proportion draining ingredients more significantly to overcome its conditions.

Here are the ingredients of our mixture for aroids in which all our aroids evolve à a few exceptions (the proportions are in photo following):< /p>

Perlite: an essential

Perlite allows good aeration of the substrate and good drainage.

It is expanded volcanic rock which is why perlite is very good

light. It is also very economical.

It allows our substrate to not be too compact while drying and having good water retention.

Note that perlite does not bind nutrients but mainly helps with adequate drainage of our substrate.

To handle it, we recommend that you wear a mask because it releases a lot of dust when handled

Horticultural charcoal: The preventative

Charcoal is an essential element for maintaining healthy roots.

Indeed, it has been scientifically proven that it fights against the appearance of rot at the roots.

Our substrate is always sensitive to the appearance of fungi (mold) due to being regularly in contact with the humidity of the watering water.

Be careful, charcoal can be very staining and releases thick black dust; remember to protect yourself.

Coconut chips: The fiber

Coconut chips are a natural and fibrous material.

Its coarse cut allows good drainage in the substrate

by giving it texture.

It promotes the development of roots without suffocating them and helps to

provide aeration in the substrate.

It is also a super water expander that can absorb 8 times its weight in water.

It’s a great ecological alternative.

Wood bark:

Wood bark brings texture to our substrate.

Any well-draining and aerated substrate greatly helps the growth of strong roots and not suffocated by a heavy and overly humid substrate.

Very important for growing orchids, wood bark is a good option for all our aroid plants.

Coconut peat: An alternative

It is a very light natural material and excellent as a water retainer.

Effectively, coconut peat retains 33% more moisture than sphagnum peat.

Coconut peat has certain physical characteristics that are very beneficial to plant growth.

Its composition does not vary the pH of your substrate, and its pH is always stable over time.

Our aroids need to grow in a substrate between pH 6 and 7, so peat is an excellent alternative.

Vermiculite is a mineral with a high water retention capacity.

Its mineral content is beneficial for plants.

Vermiculite tends to be provided with potassium, magnesium, calcium and ammonium, elements necessary for the growth of our plants.

Its water retention capacity allows it to absorb excess moisture from the soil and release it later when the substrate dries out, making it an excellent humidity regulator, which also helps to keep the substrate aerated.

Pumice: The precious stone

Pumice is roughly cut volcanic rock.

Often used as a basic substrate for Bonsai.

Pumice is definitely a very interesting natural ingredient for our plants: light and roughly cut, it is perfect for aerating the substrate and draining it.

It prevents soils from becoming muddy and roots from rotting in wet weather.

Pumice is a rock that is not very friable unlike to perlite, which offers very good stability in our substrate.

Pumice has a neutral PH and carries nutrients very well.

All-purpose sand

Coarse sand and fine gravel improve drainage.

River sand, mixed in large proportion with clay soil, will allow the roots to penetrate better.

They are both inert materials that do not modify the chemical composition of the earth.


Here are the proportions of each ingredient in our homemade aroid mix

If you have any questions, don't hesitate!
