How to Care for Aeonium arboreum Zwartkop

Proper care ensures healthy growth and longevity. Let’s explore the key factors in Zwartkop’s maintenance.

Light Requirements

Aeonium arboreum Zwartkop thrives in full sun or partial shade. In extreme heat, light shade is recommended. Rotate the plant regularly for even growth.

Watering Aeonium arboreum Zwartkop

Water moderately, allowing the soil to dry between watering. In summer, water once every 7-10 days, while in winter, reduce the frequency to once every 3-4 weeks. This allows the plant to enter dormancy and prevents root rot. Always use well-draining pots with drainage holes to avoid waterlogging.

Soil & Potting

Plant Aeonium arboreum Zwartkop in well-draining soil with a pH of 6.0-6.5. A mix of cactus soil and perlite or pumice in a 2:1 ratio works well for proper drainage. Repot every two years in spring, using a container slightly larger than the previous one. This refreshes the soil and provides room for root growth. When repotting, ensure that the base of the rosettes is level with the soil surface.

Temperature & Humidity

Zwartkop prefers temperatures between 40-100°F (4-38°C) and average humidity. Protect it from frost in colder climates.


Care for Aeonium arboreum Zwartkop with full sun or partial shade, moderate watering, well-draining soil (pH 6.0-6.5), and temperatures between 40-100°F. Repot every two years for optimal growth.

How to Propagate Aeonium arboreum Zwartkop

Propagation can be achieved through stem cuttings or offsets. The best time to propagate is during the active growing season in spring or early summer.

Stem Cuttings

Take a 3-4 inch (7-10 cm) cutting from a healthy, mature stem. Use a clean, sharp knife or scissors to ensure a clean cut. Allow the cutting to dry and callous for 3-5 days to prevent rotting. Plant the calloused cutting in well-draining soil, keeping the soil slightly moist until roots form, usually within 2-4 weeks.


Detach offsets from the mother plant using a clean, sharp knife. Let them dry for 1-2 days, allowing the cut to callous. Plant the offsets in well-draining soil, and water sparingly until roots develop, typically within 3-4 weeks. Once established, care for the new plants as you would the parent plant.

Fertilizing Your Aeonium arboreum Zwartkop

Fertilize every 4-6 weeks during the growing season with a balanced, water-soluble fertilizer. Avoid fertilizing during dormancy.

Common Pests and Diseases

Zwartkop is susceptible to pests such as mealybugs, aphids, and spider mites. Treat infestations with insecticidal soap. Prevent fungal diseases by avoiding overwatering and providing adequate airflow.
