About Aloe vera
Aloe barbadensis · also called true aloe, medicinal aloe · houseplant
Aloe vera is a sun-loving succulent from the Arabian peninsula with thick gel-filled leaves. It thrives on bright light, sparse watering, and gritty soil. The leaf gel is traditionally used for minor skin care, but consult a clinician for any medical use. Mildly toxic to pets.
Aloe vera is a leaf-succulent whose wild origin has been traced by molecular work to the Arabian Peninsula (notably the Hajar Mountains of Oman), an arid environment that shaped its drought-storage biology.
It needs a gritty, sharply drained cactus or succulent medium; in nutrient-poor native soils it forms arbuscular mycorrhizal associations that aid mineral uptake, and dense water-holding mixes promote rot.
Preferred mix: Gritty cactus and succulent mix
Watch for — Drooping or splayed leaves: Either too little light or, more often, advanced root rot.

Why aloe vera needs this mix
Aloe vera stores water in its leaves and stems, so it wants a free-draining, gritty mix that dries out fully between waterings — not a moisture-holding one.
- Aloe vera carries its own water supply in its thick tissue, so the soil's job is to drain fast and then get out of the way.
- Its roots are adapted to short wet spells followed by long dry ones — a mix that stays damp removes the dry phase they depend on.
- A gritty mix also keeps the plant compact and well-coloured rather than soft, leggy and prone to collapse.
For the full picture on what makes up a good mix, see our guide to the main types of soil and potting media — it explains why each ingredient above behaves the way it does.
What goes wrong with the wrong mix
The wrong soil is one of the most common reasons aloe vera struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Standard potting compost on its own stays wet far too long for aloe vera; the lower leaves and stem base go soft and translucent first.
- Big plastic pots full of dense mix hold a wet core long after the surface looks dry — that hidden wet zone is where rot starts.
- Anything sold as "moisture control" is the opposite of what this plant wants.
Treating aloe vera like a leafy houseplant and using plain compost. It needs at least half its volume as grit, perlite or pumice to survive long term.
pH — does it matter for aloe vera?
pH is not a concern for aloe vera — anything from mildly acidic to neutral (6.0-7.0) works. Get the drainage right and pH looks after itself.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
A good bagged "cactus and succulent" mix works for aloe vera if you add roughly 30-50% extra perlite or grit. Mixing your own from the ratio above gives you full control of how fast it dries.
Drainage and the pot
Use a pot with a drainage hole and empty the saucer within minutes of watering. Terracotta is more forgiving than glazed or plastic because it dries the rootball faster.
This mix decomposes slowly, so aloe vera only needs repotting every 2-3 years — mainly to refresh the grit and check the roots are firm and pale. When the time comes, our repotting guide for aloe vera covers the timing and technique step by step.
Aloe vera soil — frequently asked questions
What is the best soil mix for aloe vera?
2 parts standard cactus or succulent compost : 1 part perlite or pumice : 1 part coarse grit or coarse sand. Aloe vera carries its own water supply in its thick tissue, so the soil's job is to drain fast and then get out of the way.
Can I use normal potting soil for aloe vera?
Standard potting compost on its own stays wet far too long for aloe vera; the lower leaves and stem base go soft and translucent first. A good bagged "cactus and succulent" mix works for aloe vera if you add roughly 30-50% extra perlite or grit. Mixing your own from the ratio above gives you full control of how fast it dries.
Does aloe vera need a special pH?
pH is not a concern for aloe vera — anything from mildly acidic to neutral (6.0-7.0) works. Get the drainage right and pH looks after itself.
Should I buy a bagged mix or make my own for aloe vera?
A good bagged "cactus and succulent" mix works for aloe vera if you add roughly 30-50% extra perlite or grit. Mixing your own from the ratio above gives you full control of how fast it dries.
