What to do if the violet leaves are rotten

1. Place in a ventilated place

(1) Specific reasons: Sometimes, we are not careful when watering and water splashes onto the leaves. Or when spraying water in summer, a lot of water remains on the leaves and does not evaporate. These situations may cause the leaves to rot.

(3) Mosaic disease: This disease mainly targets leaves and flowers, and the leaves are severely affected. Its virus is mainly transmitted by aphids, so it can be combined with pest control.

(4) Aphids: This is the main type of pest. In addition, as mentioned above, insects can also spread certain types of viruses, causing other diseases. Special insecticides such as imidacloprid can be used.
