Care Guide
Aeonium Zwartkop is a relatively easy plant to care for, but it does have specific requirements to keep it healthy and looking its best. Here are some essential tips for caring for your Aeonium Zwartkop:
Water
Aeonium Zwartkop prefers well-draining soil and does not tolerate standing water. Allow the soil to dry out between waterings, and be sure to water deeply when you do water to encourage deep root growth. During the winter months, reduce watering to once every two to three weeks.
Fertilization

Soil
Aeonium Zwartkop prefers well-draining soil that is rich in organic matter. A mix of sand, perlite, and peat moss is a good choice for potting soil. If planting in the ground, be sure to amend the soil with compost or other organic matter to improve drainage.
Sunlight
Aeonium Zwartkop prefers full sun to partial shade. In areas with hot, intense sun, it may benefit from some afternoon shade to prevent sunburn on its leaves.

Regularly inspect your plant for signs of pests, and if you notice any, treat them immediately with insecticidal soap or neem oil. Overwatering can lead to root rot, so be sure to allow the soil to dry out between waterings.

Question and Answer
Q: Can Aeonium Zwartkop be propagated?
A: Yes, Aeonium Zwartkop can be propagated from stem cuttings. Simply cut a stem from the plant and allow it to callus over for a day or two before planting it in well-draining soil. Keep the soil moist and out of direct sunlight until the cutting has rooted.
Q: Why are my Aeonium Zwartkop’s leaves turning yellow?
A: Yellowing leaves can be a sign of overwatering, underwatering, or nutrient deficiencies. Check the soil moisture and adjust your watering schedule as needed. If the soil is consistently wet or waterlogged, allow it to dry out before watering again. A balanced, slow-release fertilizer can help address nutrient deficiencies.
