How to Grow and Care for Aeonium Arboreum
Master the care of Aeonium arboreum by understanding its distinct seasonal needs, from its active growth in cooler months to its necessary summer rest.
Aeonium arboreum, often called the tree aeonium, is a striking succulent known for its glossy, rosette-forming leaves atop branching stems. Native to the Canary Islands, this plant adds architectural interest to gardens and container arrangements. Its care requirements are straightforward, making it a popular choice for many growers.
Care Guide
Light
These succulents thrive in full sun to light shade. Providing at least six hours of direct sunlight per day encourages compact growth and brings out deep colors in the foliage. In extremely hot climates, some afternoon shade can prevent leaf scorch.
Soil
Proper soil is important for preventing root rot. Use a well-draining cactus or succulent mix. Amending the soil with perlite or coarse sand will improve drainage and aeration for the root system.
Watering
Water Aeonium arboreum using the “soak and dry” method. Drench the soil completely and then allow it to dry out entirely before watering again. Reduce watering frequency significantly during the summer dormancy period.
Fertilizer
This plant does not require heavy feeding. During the active growing seasons of spring and fall, you can apply a balanced, diluted liquid fertilizer once a month. Do not fertilize while the plant is dormant in the summer.
Temperature and Humidity
Aeonium arboreum prefers mild climates and is not frost-tolerant. Protect it from temperatures below freezing. The plant is well-suited to average household humidity levels and does not have special requirements.
Dormancy
Unlike many succulents that grow in the summer, Aeonium arboreum is winter-growing and goes dormant in the summer heat. During dormancy, the rosettes will close up, with leaves curling inward to conserve moisture. The plant requires less water during this resting phase.
Pruning and Propagation
Pruning can be done in the fall to shape the plant or encourage a fuller appearance. Use clean, sharp shears to cut the stems. These cuttings can be used for propagation. Allow the cut end of a stem to dry and form a callus for a few days before planting it in well-draining soil.
Common Issues
Overwatering is the most frequent problem, leading to root rot. Ensure the soil dries out between waterings. Pests such as mealybugs and aphids can sometimes appear, so inspect the plant regularly. Insufficient light will cause the plant to stretch and become leggy, a condition known as etiolation.
