Care

Let the soil dry out completely between waterings to prevent root rot. Watch for mushy leaves which indicate overwatering, or thin wrinkled leaves that suggest the plant needs a drink. Ensure your pot has drainage holes to keep the roots happy.

Watering: Water deeply only when the soil has dried out entirely.
Feeding: Feed with a balanced liquid fertilizer diluted to half strength during the growing season.
Pruning: Trim away any dead or damaged outer leaves at the base using clean shears.
Repotting: Move to a slightly larger container once the plant becomes root bound.

Signs it needs repotting

Safety

People: The outer leaf skin contains aloin, which is a potent laxative and can cause stomach cramps if ingested.
Pets: This plant is toxic to cats and dogs if ingested.
Children: The sharp, serrated leaf edges can scratch young children, and the plant should be kept out of reach to prevent accidental ingestion.
Contact allergens: The sap can cause contact dermatitis in sensitive individuals.
Airborne allergens: Pollen from flowering aloe can trigger mild respiratory reactions in some people.
Edibility: Only the inner gel of Aloe vera is considered safe for consumption, and improper preparation can cause severe digestive distress.

Growing it

Propagation: offsets, seed
When to plant: spring, summer
Overwintering: Bring the plant indoors before the first frost. Keep it in a bright spot and reduce watering significantly during the winter months.
In containers: Aloe grows very well in containers, provided the pot has excellent drainage and is not too large.

Offset Division

Wait for the mother plant to produce small offsets or pups at the base.
Gently remove the pup from the parent, ensuring it has some roots attached.
Let the pup dry for a few days to callus over.
Plant the pup in a well-draining succulent potting mix.

Group succulents with similar water needs to avoid accidental overwatering of your aloe.
