Root Rot

Overwatering

To address root rot in elephant bush, first, allow the soil to dry out completely before watering again. If the plant is severely affected, remove it from its pot, trim away any black, mushy roots, and repot in fresh, well-draining soil. Consider using a pot with better drainage and adjust your watering schedule to prevent future occurrences. Monitoring soil moisture before watering can help avoid overwatering. In severe cases, propagation from healthy parts may be necessary.

Leaf Drop

Underwatering

Elephant bush (Portulacaria afra) is drought-tolerant but still requires consistent moisture to thrive. To prevent leaf drop due to underwatering, establish a regular watering schedule, allowing the soil to dry out slightly between waterings. Use a well-draining soil mix to prevent waterlogging. During the growing season, water the plant more frequently, and reduce watering in the winter. If leaf drop occurs, gradually increase watering frequency without overwatering to allow the plant to recover.

Mealybugs Infestation

Mealybugs are small, soft-bodied insects covered with a white, powdery wax. They feed on the sap of the elephant bush, weakening the plant and causing stunted growth.

To combat mealybugs, start by isolating the affected plant to prevent the spread to others. Use a cotton swab dipped in rubbing alcohol to dab directly onto the pests, effectively killing them. For larger infestations, rinse the plant with a strong stream of water to dislodge the pests, or apply insecticidal soap or neem oil, following the product's instructions. Ensure to treat the plant regularly until the mealybugs are completely eradicated. Additionally, maintaining proper watering and care can help prevent future infestations.

Leaf Drop

Environmental Stress

Elephant bush is sensitive to changes in its environment, such as sudden temperature fluctuations, low humidity, or inadequate lighting. To prevent leaf drop, maintain a stable environment with temperatures between 60-80°F (15-27°C), provide bright, indirect light, and increase humidity around the plant if the air is too dry. Gradually acclimate the plant to any new location by slowly introducing it to new conditions over several weeks.
