Aloe vera is a plant that is used more extensively than any other aloe out there. It has an abundance of value for health and can be grown in containers as a houseplant with the right care and guidance. In this article, find out what the perfect soil mix is for aloe vera grown in pots, the most important part of growing this plant.

The Short Answer

The important part of the plant Aloe vera is the ‘aloe’. This will give us some clues as to how to treat them and what kind of soil they prefer. As a succulent plant hailing from the hot and dry regions of Africa, Asia, Europe, and the Americas, it is, in its natural habitat, grown in sandy soil with minimum water. So, the short answer is sandy soil.

The Long Answer

A miniature aloe vera plant flaunts its petite, textured leaves, each brimming with vitality. Nestled within a spacious pot, it thrives amid rich brown soil and a mulch of rice hulls, providing a nurturing environment. Bathed in the warm embrace of sunlight, its leaves gleam with vitality, vibrant and lush.
Everyone seems to have their own unique soil mix recipe for succulents and aloe.

If you ask succulent and aloe growers what soils they recommend, you will find that everyone has a different recipe for their soil mix. They can all agree that it should be well-draining and, when in doubt, use a commercially available substrate specially formulated for cacti and succulents.

Never use soil from the garden. Once you know what each part of a potting mix does, it will be easier to make your own.

The Basic Recipe

A close-up of potting soil shows rich, dark earth teeming with nutrients, tiny roots peeking out. Perlites, small white specks, bring aeration and drainage, resembling mini marshmallows in the fertile soil bed, enhancing growth.
Play around with varying material ratios to tailor your soil mix to your specific location.

Experiment with different ratios of materials to find the best one for your area. The climate, fluctuations in temperature, and humidity will all affect your soil, but you can start with the basic recipe as follows:

  • 1 part porous material like perlite, pumice, or Akadama
  • 2 parts drainage materials such as coarse sand or grit
  • 2 parts organic materials such as potting soil (with compost added)

Mix all these ingredients well together before using them in containers.

Porous Materials

General potting soil mixes retain moisture for plants. This is a good thing for most plants but not for an aloe like aloe vera or any succulent. Provide quick-draining soil to avoid water-logging the roots. This will be detrimental to their health and may cause root rot and even death. There are various ways to include porous materials into the mix, some with other super benefits. Choose any of these for your mix.

Perlite

An array of perlites—small, lightweight, and porous volcanic stones. Each perlite, resembling a miniature sponge, holds moisture and air, fostering healthy root growth. A steel scoop gathers a handful, their texture lightweight yet durable against the scoop's edge.
This component possesses a porous structure that retains some water while facilitating drainage.

What you might think are polystyrene balls in the soil mix you find at the nursery is, in fact, a volcanic rock that has been expanded using extremely high heat, becoming very lightweight and useful as a horticultural substrate. In its natural environment, perlite is an amorphous black or grey glass with a substantial list of beneficial plant nutrients, including potassium, iron, manganese, and calcium.

The perlite is mined and then processed to produce the light material in a process nicknamed ‘volcanic popcorn’ making. The water content in perlite will make it pop at very high temperatures of around 1650°F. Once popped, the perlite is up to 16 times bigger and significantly lighter.

The benefits of adding perlite to a soil mix are that it is stable (unlike polystyrene, which can be squashed), has a neutral pH level, is still able to retain some water in its porous structure but allows water to drain away, and helps aerate the soil so the roots can ‘breathe.’ It also helps improve drainage, which is essential for succulent and aloe soil mixes.

Pumice

On a white table, a plate holds dark pumice stones, textured with porous surfaces and irregular shapes. Some stones rest scattered across the table, varying in size and shade, creating a rugged, natural arrangement of earthy elements.
Pumice is abundant in valuable trace elements and is obtained by crushing lava rocks.

Very similar to perlite, pumice is a mined mineral created by crushing lava rocks, and it is full of beneficial trace elements. It is lightweight and has tiny craters on its surface that hold air, water, and nutrients in the soil while assisting with drainage and releasing water when necessary.

Pumice is naturally lightweight and has been caused by the reaction of lava with high water content, causing gases to expand and the lava to bubble and fizz. Once cooled, the rock contains the tiny air bubbles that give it porous properties.

Of particular interest is the fact that pumice contains up to 70 beneficial trace elements that can assist with keeping your aloe healthy.

Akadama

A close-up reveals dry Akadama soil, characterized by its granular, reddish-brown appearance and distinct grains. A small shovel delicately scoops the soil, showcasing its fine texture, and is placed on a brown table, accompanied by small rocks, displaying a miniature landscape.
One distinctive feature of Akadama is its color transformation when moist.

Mined in Japan, Akadama is another volcanic rock substrate that has been used for growing bonsai for many years. It’s used for its properties, which include water retention and nutrients, as well as being a porous material that assists in drainage and aeration.

What is special about Akadama is the color change it has when wet. The darker color indicates high water content; as it gets lighter, the plants require water. It’s like its own water sensor. In recent years, it has become popularized for use in growing succulents and cacti.

Drainage Material

Sand must be included to mimic the soil of the hot and dry regions from which aloe vera originates.

Sand, Gravel, and Grit

A combination of fine sand, coarse gravel, and gritty particles in earthy hues, forming a balanced mix for aloe. The sand appears fine-grained, the gravel shows varying sizes, and the grit offers a textured, blended composition.
A well-balanced aloe mix relies on multiple particle sizes for optimal plant health.

Making up the bulk of a good aloe mix is sand of different sizes, which helps trap air in pockets and allow the roots to get much-needed aeration. Large gravel particles are good for a layer at the bottom of the pot to help prevent soil from escaping through the drainage holes, and smaller sand particles throughout the mix will help with drainage along with the characteristics of the porous material discussed above.

Organic Materials

Potting Soil and Compost

White sacks of composted potting soil stacked; one open sack reveals a rich blend of dark soil and organic compost. The potting soil exudes a dark, nutrient-rich texture, interspersed with decomposed matter, ideal for planting and nourishing growth.
Enhance the soil’s nutrient content by adding some quality compost to your mix.

Like any plant, aloe vera does require nutrients to grow and flourish. This is where materials like potting soil come in. Potting soil comprises 50% organic matter, compost, and solid materials like minerals, sand, silt, and clay. The rest is 25% water and 25% air for oxygen.

Specifically for succulents like aloe vera, a fine potting soil or even a seedling (germination) mix can be used because the bark chips are usually smaller. A bark size of 0.2 – 0.3 inches is ideal.

To add more nutrients to this formula, add a couple of handfuls of good compost to your mix.

A good potting soil has the right structure and nutrients to conserve moisture, provide oxygen, and anchor the plant’s roots.

Final Thoughts

The soil mix is very important to maintaining a healthy aloe. Without a good mix, there is the chance that roots could be damaged, and the plant can suffer and even die. It is essential to take the time to prepare soil mixes well with the right ingredients for the best chance of success.
