Root Rot

Overwatering

To address root rot, first, stop watering the plant and allow the soil to dry out. If the plant is severely affected, remove it from its pot and trim away any black, mushy roots, leaving only healthy, white roots. Repot the plant in fresh, well-draining soil and a clean pot. Ensure the pot has adequate drainage holes. Going forward, water the plant only when the top inch of soil feels dry to the touch, avoiding waterlogging.

Leaf Spot Disease

Fungal or bacterial pathogens

To manage leaf spot disease, it's crucial to maintain a clean environment around your Song of India plant. Remove and dispose of any infected leaves to prevent the spread of the disease. Improve air circulation around the plant to reduce humidity levels, which can exacerbate the problem. If the infection is severe, applying a fungicide or bactericide, as appropriate, according to the product's instructions, can help control the disease. Always ensure the plant is not stressed by environmental factors, as a healthy plant is more resistant to diseases.
