Aloe Vera Care: Light, Watering, and Common Problems
The short answer
Give aloe vera bright, indirect sunlight, and water it thoroughly but only after the soil has dried out completely. South Dakota State University Extension notes that regular, thorough watering with the soil drying fully between drinks is best, and that a plant left sitting in water is susceptible to root rot, which can be fatal if not caught early.
Pot it in sandy soil or a pre-mixed cactus medium in a container with drainage holes, keep it between about 55 and 85 degrees F, and skip the humidifier: aloe does not need extra humidity, and ordinary dry indoor air suits it.
What Aloe Vera Is
Aloe vera (also called medicine plant, Barbados aloe, or true aloe) is a succulent that stores water in its thick, fleshy leaves. Because it naturally grows in nutrient-poor soil, it needs little feeding; SDSU Extension notes no fertilizer is usually required to keep the plant healthy.
Light: Bright but Indirect
Aloe requires bright, indirect sunlight; harsh direct sun can burn its tender skin. If the plant is not getting enough light, growth turns leggy and the leaves droop, so move a struggling plant closer to a bright window rather than farther away.
Watering: The Number One Killer
Overwatering kills more aloes than anything else. The rule is soak and dry: water thoroughly, then wait until the soil dries out completely before watering again. Iowa State University Extension describes the same technique for succulents generally: thoroughly wet the entire root ball until water drains, then let the soil dry completely before the next watering.
Cut back further in winter, when the plant is semi-dormant. Yellow, shriveled, puckered leaves signal underwatering; a mushy base or constantly wet soil points to root rot from overwatering.
⚠ Never let the pot sit in a saucer of water. SDSU Extension warns that an aloe sitting in water is susceptible to root rot, which can be fatal if not caught early.
Soil, Pot, and Drainage
Use sandy soil or a pre-mixed cactus potting medium in a pot with drainage holes. Iowa State Extension stresses that containers for succulents must have drainage holes and that a gravel layer at the bottom is no substitute for a real hole.
Temperature and Humidity
- Keep aloe between roughly 55 and 85 degrees F, close to its natural environment.
- It cannot tolerate frost, so bring outdoor plants in well before cold nights.
- No extra humidity needed; dry winter indoor air is ideal.
Common Problems and Pests
- Root rot: caused by overwatering or poor drainage; often fatal if caught late.
- Mealybugs, aloe scale, and aloe mite: SDSU Extension notes insecticidal soap can be used to control mealybugs.
- Fungal disease: encouraged by cool temperatures plus high humidity.
- Leggy, drooping growth: a light problem, not a water problem.
→ Aloe should not be ingested by people or pets; SDSU Extension notes it can cause nausea and indigestion in large quantities. If you have cats or dogs, check the ASPCA toxic and non-toxic plant list before bringing one home.
