1、 Illumination

Rieger Begonia likes half shade. During indoor potted maintenance, in addition to proper shading in summer, you can get more sunshine in other seasons. However, if you want Rieger Begonia to bloom, you need to ensure that the sunshine duration every day is less than 13 hours. After all, it is a short sunshine plant

2、 Temperature

Rieger Begonia can grow normally in the environment of 10-28 ℃. If the temperature is lower than 10 ℃ in winter, the water should be properly controlled. Otherwise, if the temperature is low and watering is large, Rieger Begonia is easy to be frostbitten. If the temperature exceeds 30 ℃ in summer, measures such as sunshade and water spray should be taken to cool down

3、 Watering

Rieger Begonia likes dampness and is afraid of waterlogging. During the growth period, it is necessary to wait for the soil surface to turn white and become dry. In winter, the temperature is low to keep the soil dry. When watering, it is also necessary to avoid watering on flowers and leaves to prevent plants from falling flowers and rotten leaves

4、 Fertilization

Rieger Begonia likes to apply thin fertilizer frequently. It can apply nitrogen, phosphorus and potassium balanced fertilizer and water during the growth period to promote plant growth. Before flowering, it can use phosphorus and potassium fertilizer to promote plant flowering

5、 Pruning

Rieger Begonia has a large amount of flowers and a long flowering period. If there are too many flower buds at the top of a branch, you can properly sparse the buds, remove the weak and retain the strong. At ordinary times, once you find old or diseased leaves, you can remove them at any time to prevent the occurrence of diseases and pests

6、 Diseases and insect pests

Rieger Begonia is particularly fond of diseases and pests. For example, if it is watered too much, Rieger Begonia is prone to stem rot and root rot, which can be controlled by carbendazim. If the ventilation is poor, Rieger Begonia is easy to produce aphids and thrips. Imidacloprid can be used for control, and more ventilation is needed at ordinary times
