5. Light: Begonia likes semi-shaded environment, insufficient light time easily leads to thin leaves, too long light time or too strong light easily leads to low plant growth, purple leaves thick, flower buds do not open. Therefore, in summer, attention should be paid to avoid direct sunlight begonia, winter to ensure that the begonia to provide sufficient light time. In addition, it is necessary to change the orientation of the flowerpot frequently so that the whole plant receives light evenly.

Once the leaf spots are found, the diseased leaves should be cut off immediately, and indoor ventilation should be strengthened to reduce environmental humidity.
