Root Rot

Overwatering

To address root rot in Kalanchoe flapjack, first, cease watering immediately and allow the soil to dry out. If the plant is severely affected, remove it from its pot, trim away any black, mushy roots, and repot in fresh, well-draining soil. Ensure the pot has adequate drainage holes. Going forward, water only when the top inch of soil feels dry to the touch, and avoid letting the pot sit in standing water to prevent recurrence.

Mealybugs Infestation

Mealybugs are small, soft-bodied insects covered with a white, powdery wax. They typically feed on the sap of the kalanchoe, weakening the plant.

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 more severe infestations, applying neem oil or insecticidal soap directly to the plant every 7-10 days can be effective. Ensure to cover all parts of the plant, including the undersides of leaves. Regular monitoring and early intervention are key to preventing future infestations.

Powdery Mildew

Fungal infection

Powdery mildew is a common fungal issue that affects many plants, including the kalanchoe flapjack. It appears as white or gray powdery spots on the 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 destroyed. For severe infections, apply a fungicide suitable for powdery mildew, following the manufacturer's instructions. Preventive measures include using a neem oil spray as a natural option.
