Important Pests and Control Methods - Powdery Mildew: This mainly occurs in poorly ventilated or densely planted environments. When it occurs, use a fungicide or remove the diseased parts.
 - Aphids: They inhibit growth by sucking plant sap. They can be controlled by washing them with soapy water or using appropriate insecticides.
