If a specific disease is identified, take targeted action to address it. For leaf scorch, provide shade or protection from direct sunlight and ensure adequate soil moisture. For fungal diseases, consider using approved fungicides as per the manufacturer’s instructions. In the case of insect pests, utilize organic or chemical-based insecticides as a last resort, and focus on promoting the overall health and vigor of the plant to make it less susceptible to infestations.
