Leaf spots: Fungal or bacterial infections can cause leaf spots which can lead to premature leaf drop. Control leaf spots by ensuring proper drainage and airflow around the plant. Avoid overhead watering and remove infected plant debris. Fungicides and bactericides can also be used.
Powdery mildew: This is a fungal disease characterized by the appearance of white powder-like substance on the leaves. Powdery mildew can cause stunted growth and leaf drop. Control powdery mildew by ensuring adequate airflow around the plant, avoiding overhead watering and applying fungicides.
Root rot: Excessive moisture in the soil can cause root rot which can be fatal to the plant. Control root rot by improving soil drainage and avoiding overwatering. Fungicides can also be used.
Pests:
Aphids: These are small, pear-shaped insects that suck the sap from the plant leaves. They can cause stunted growth and curling of leaves. Control aphids by spraying the plant with insecticidal soap or neem oil.
Spider mites: These are tiny pests that are difficult to see with the naked eye. They spin webs on the plant and suck the sap from the leaves. This can cause discolored leaves and stunted growth. Control spider mites by spraying the plant with insecticidal soap or neem oil.
Caterpillars: These are the larvae of moths and butterflies that can cause defoliation and damage to the plant. Control caterpillars by handpicking them or using biological controls like Bacillus thuringiensis (Bt).
