Care

Light

Aeonium arboreum thrives in bright, indirect sunlight. Aim for at least six hours of light daily to maintain its vivid leaf color and healthy growth. While it can tolerate some direct sun—particularly in cooler climates—harsh afternoon sunlight in summer may cause leaf scorch. In warmer regions, consider using filtered light or partial shade during peak sun hours. If natural light is limited, supplement with a grow light.

Temperature & Humidity

Aeonium arboreum prefers moderate temperatures between 65–75°F (18–24°C). It can tolerate occasional drops to 40°F (4°C) but should be protected from frost. Indoors, keep the plant away from cold drafts or heat sources. This succulent adapts well to average household humidity and does not require additional moisture.

Watering

Although Aeonium arboreum enjoys slightly more moisture than some succulents, it still benefits from the "soak and dry" method. Water thoroughly, let excess drain, and allow the soil to dry completely before watering again. During the active growing seasons (spring and fall), water every two to three weeks. In summer, the plant enters dormancy—growth slows, and some leaves may drop—so reduce watering significantly. Always adjust based on your environment’s humidity and temperature.

Soil

Use a well-draining cactus or succulent potting mix to prevent water retention and reduce the risk of root rot. You can also create your own mix by blending regular potting soil with coarse sand or perlite.

Maintenance

Pruning

Prune as needed to remove dead or yellowing leaves and encourage a bushier appearance. Pruning can be done year-round, but expect slower regrowth during the plant’s summer dormancy.

Cleaning

Dust may accumulate on Aeonium leaves, particularly indoors. Use a soft brush or cloth to gently remove dust and debris, improving light absorption and deterring pests.

Rotation

Rotate the plant every couple of weeks to ensure all sides receive equal light. This encourages balanced growth and helps prevent legginess.

Repotting

Repot every 2–3 years or when the plant becomes root-bound. The best time to repot is in early spring or fall when the plant is actively growing. Signs of being root-bound include roots circling the base or emerging from drainage holes. Use a pot with good drainage and refresh the soil to support continued growth.

Fertilization

Feed monthly during the growing seasons (spring and fall) using a balanced, water-soluble fertilizer diluted to half strength. Avoid fertilizing during the summer dormancy period when the plant's growth slows.

Propagation

Aeonium arboreum is easy to propagate through stem cuttings:

1. Use sterilized scissors or pruning shears to cut a healthy stem.
2. Allow the cutting to callous over for a few days.
3. Plant the cutting in well-draining soil.
4. Keep the soil lightly moist until roots develop—this typically takes a few weeks.

Once rooted, care for the new plant as you would a mature Aeonium.

Common Issues

Pests

• Types: Aphids, mealybugs, spider mites, slugs, and snails (particularly outdoors).
• Solution: Treat infestations with insecticidal soap or neem oil, reapplying every few days as needed. Inspect regularly to catch problems early.

Root Rot

• Cause: Overwatering or poorly draining soil causes excess moisture around the roots, encouraging fungal growth.
• Symptoms: Wilting, yellowing leaves, soft stems, blackened or mushy roots, and a foul-smelling potting mix.
• Solution: Remove the plant from its pot and inspect the roots. Use sterilized scissors to trim away affected areas. Allow the plant to dry slightly, then repot in fresh, well-draining soil. Ensure the new pot has drainage holes and adjust your watering routine accordingly.

Yellowing Leaves

• Cause: Can result from natural leaf aging, overwatering, or inadequate drainage.
• Solution: It’s normal for older, lower leaves to yellow and drop off. If yellowing is widespread, check soil drainage and reduce watering frequency.

With the right balance of light, water, and care, Aeonium arboreum can thrive as a bold, architectural addition to your succulent collection. Its branching form and rosettes offer visual interest year-round with relatively little maintenance required.
