Root Rot

Overwatering

To address root rot in Aeonium 'Pinwheel', it's crucial to first allow the soil to dry out completely before considering any further watering. If the plant is in a pot, ensure it has adequate drainage holes. In severe cases, removing the plant from its current soil, trimming away any black, mushy roots, and repotting in fresh, well-draining soil can help. Adjust your watering schedule to avoid future overwatering, ensuring the topsoil is dry between waterings.

Leaf Shriveling and Dropping

Underwatering

Aeonium pinwheel requires consistent moisture, especially during its active growing season in the cooler months. To address underwatering, gradually increase watering frequency, ensuring the soil is moist but not waterlogged. Implement a regular watering schedule, checking the soil's moisture level before watering. If the soil dries out too quickly, consider repotting the plant into a slightly larger container with fresh, well-draining soil to retain moisture more effectively.

Aphid Infestation

Aphids are small, sap-sucking insects that can infest Aeonium 'Pinwheel', leading to weakened plants, distorted growth, and potential disease transmission.

To manage aphid infestations, start by rinsing the plants with a strong jet of water to dislodge the pests. For persistent issues, apply insecticidal soap or neem oil, focusing on the undersides of leaves where aphids commonly reside. Ensure thorough coverage for effectiveness. In severe cases, consider using systemic insecticides, but always follow the product's instructions and consider the environmental impact. Regular monitoring and early intervention are key to preventing significant damage.

Powdery Mildew

Fungal infection

Powdery mildew is a common fungal issue that affects Aeonium 'Pinwheel', manifesting as white, powdery spots on leaves. To manage this, ensure good air circulation around your plants and avoid overhead watering to keep the foliage dry. Infected leaves should be removed and disposed of promptly. For severe infections, apply a fungicide suitable for succulents, following the manufacturer's instructions carefully. Preventive measures include using a neem oil spray as a natural fungicide and maintaining a well-spaced garden to reduce humidity levels around your plants.
