Causes of flower diseases: First, poor cultivation environment, such as excessive or insufficient moisture, light intensity is too strong or too weak, too high or too low temperature, nutrient deficiencies or disorders, as well as smoke and dust, harmful gas pollution and other diseases, This is also called a physiological disease. This type of disease affects the growth and development of flowers, but it is not contagious. The second is the infection of pathogens, such as fungi, bacteria, viruses, etc., which invade the plant body. Among them, diseases caused by fungal infection are the most common. This type of disease can rapidly spread infection under suitable environmental conditions.
For diseases caused by poor environmental conditions, as long as timely improvement of cultivation and management, adapt to the requirements of flower growth and development, generally will naturally rejuvenate. Diseases of pathogenic bacteria must be controlled in time. However, these two types of diseases are closely linked and mutually causative. When the flower grows weak, it is often easy to incur the disease; sometimes the flowers are pests, which can also lead to disease.
