Root Rot

Overwatering

To address root rot in banana croton, first, allow the soil to dry out before watering again. Ensure the pot has adequate drainage holes and consider repotting the plant into fresh, well-draining soil. If the plant is severely affected, you may need to trim away the rotted roots before repotting. Regularly check the soil moisture and establish a watering schedule that maintains the soil slightly moist but not waterlogged.

Leaf Spot Disease

Fungal pathogens such as Cercospora spp.

To manage leaf spot disease, it's crucial to maintain good air circulation around your plants by not overcrowding them. Remove and destroy any infected leaves to prevent the spread of the fungus. Avoid overhead watering to keep the foliage dry. If the infection is severe, applying a fungicide specifically labeled for leaf spot diseases on ornamental plants can be effective. Always follow the manufacturer's instructions when using fungicides.
