The changes in the African violet can be easily identified if observed carefully. The main disease that affects the plant is decaying of its roots and leaves. This disease is caused by fungus formed due to changes in moisture and other rapid changes in the climate. Watering must be done with utmost care. Fungicides like bavistin are the best remedy for such diseases.
If the plant is severely affected by the fungus, it must be immediately removed from the mixture, leaves and stems thoroughly washed and kept dipped in fungicide solution. Later the plant can be replanted into a new mixture..Premature flower shedding is probably due to aphid attack. This can be prevented by spraying the plant with water mixed with six to seven drops of Imidacloprid dissolved in it. Proper care and remedial measures to protect plants can help you to create and maintain a beautiful garden.
