Aloe vera: The Complete Guide
to Successful Care
Few plants combine as many assets as aloe vera: an instantly recognizable graphic silhouette, some of the easiest care around, and an inner gel traditionally used for centuries to soothe minor burns and skin irritations. It's a succulent plant that stores water in its thick leaves, which explains both its tolerance to neglect and its vulnerability to the only real danger it faces: overwatering.
Placed on a sunny windowsill, a well-cared-for aloe vera can live for several decades and regularly produce new offsets to share or replant, allowing a collection to grow effortlessly over the years.
Identity Card
Ideal Light
Full sun doesn't scare it
Aloe vera thrives in very bright light, ideally a few hours of direct sun per day, such as on a south-facing windowsill. Lack of light results in etiolated leaves that become thin and lean towards the nearest light source, losing their characteristic upright posture.
Watering
Allow to dry completely between waterings
Water generously until water drains from the drainage hole, then allow the substrate to dry completely before the next watering — typically 2 to 3 weeks in summer, and 4 to 6 weeks in winter. Soft and translucent leaves almost always indicate overwatering, while slightly wrinkled leaves indicate a lack of water, which is far less serious and easily corrected.
"Aloe vera stores water for you.
Your role is mostly not to bother it too often."
Substrate and repotting
A special cactus and succulent mix
A special cactus and succulent soil mix, or a universal potting mix lightened with 30 to 50% coarse sand or perlite, ensures sufficient drainage. Repot every 2 to 3 years, or as soon as the offsets become too numerous for the pot, into a container always equipped with a drainage hole.
Fertilization
A light input, rarely necessary
Fertilize every 4 to 6 weeks during the active growing season, at a reduced dose. Aloe vera thrives even without any fertilizer, as its naturally slow growth requires few additional nutrients.
Multiplication by offsets
Over time, a healthy aloe vera naturally produces offsets ("babies") at its base. Once they reach a few centimeters with their own roots, gently separate them from the mother plant and replant them in a well-draining substrate — a much simpler propagation method than classic cuttings.

⚠ Toxicity for animals
Although the gel is traditionally used on human skin, aloe vera is slightly toxic if ingested by cats and dogs, causing digestive problems. Place it out of reach of curious animals. For a risk-free home, consult our selection of non-toxic plants for pets.
Common Problems
Aloe vera generally remains very robust, but certain signs deserve your attention:
| Symptom | Probable Cause |
|---|---|
| Soft and translucent leaves | Overwatering, beginning of rot |
| Thin, leggy leaves | Lack of light |
| Sudden brown spots | Sunburn after too abrupt exposure to the sun |
| Wrinkled leaves | Lack of water, easily corrected |
| Blackened base | Advanced rot due to prolonged overwatering |
Mistakes to avoid
- ❌ Watering too often "just in case", the number one cause of death for this plant
- ❌ Using unlightened universal potting soil, which retains too much moisture
- ❌ Abruptly exposing to full sun a plant accustomed to softer light
- ❌ Choosing a pot without a drainage hole
- ❌ Separating an offset too young, before it has developed its own roots
Frequently Asked Questions
Short answers to the questions we are most often asked about aloe vera.
How often should I water an aloe vera?
Generally every 2 to 3 weeks in summer and every 4 to 6 weeks in winter. The most reliable method is to check that the substrate is completely dry before watering again.
Can I use the aloe vera gel from my own plant?
Yes, the clear gel inside the leaves is traditionally used to soothe minor superficial burns. Harvest an outer, well-matured leaf rather than the young central shoots.
Why are my aloe vera leaves getting soft?
This is almost always a sign of overwatering. Check the pot's drainage and drastically reduce watering, letting the substrate dry completely.
Is aloe vera toxic to cats and dogs?
Yes, slightly, if ingested. It is best to place it out of reach of curious animals, even if the gel is traditionally used safely on human skin.
How do I propagate an aloe vera?
The simplest way is to wait until it produces offsets at its base, then separate them once they have developed their own roots, to replant them in a well-draining substrate.
Why does my aloe vera have brown spots?
This is often sunburn due to too sudden exposure to full sun after a period of softer light. Reintroduce direct sun gradually after a change of location.
Should I fertilize an aloe vera?
It is not essential. A light application from March to September can support growth, but many aloe veras thrive perfectly well without any fertilizer.
In summary
- ✅ Bright light, ideally a few hours of direct sun
- ✅ Water rarely, let dry completely between waterings
- ✅ Well-draining substrate (special cactus and succulents) and pot with drainage hole
- ✅ Light fertilizer from March to September, not essential
- ✅ Easy propagation by separating offsets
