How to grow Rieger Begonia

1. Lighting

Regis Begonia prefers partial shade. When caring for it in indoor potted plants, it needs proper shading in the summer, but it can be exposed to more sunlight in other seasons. However, if you want the Regis Begonia to bloom, you need to ensure that the daily sunshine time is less than 13 hours. After all, it is a short-day plant.

2. Temperature

Begonia can grow normally in an environment of 10-28℃. When the temperature is below 10℃ in winter, you need to control the water appropriately. Otherwise, due to low temperature and excessive watering, Begonia can easily get frostbite. When the temperature exceeds 30℃ in summer, you need to use measures such as shading and spraying water to cool it down.

3. Watering

Begonia likes moisture but is afraid of waterlogging. During the growing season, wait until the soil surface turns white and dry before watering thoroughly. In winter, when the temperature is low, keep the soil dry. When watering, be careful to avoid watering the flowers and leaves to prevent the plants from falling flowers and rotting leaves.

4. Fertilization

Begonia likes thin fertilizers applied frequently. You can apply balanced fertilizers with nitrogen, phosphorus and potassium during the growing season to promote plant growth. Before flowering, use phosphorus and potassium fertilizers to promote flowering.

5. Pruning

Begonia has a large number of flowers and a long flowering period. If there are too many flower buds on the top of a branch, you can thin them out appropriately, removing the weak ones and keeping the strong ones. Once old or diseased leaves are found, they can be removed at any time to prevent the occurrence of diseases and pests.

6. Pests and diseases

Begonia is particularly prone to diseases and pests. For example, if it is watered too much, it will easily get stem rot and root rot, which can be prevented and controlled with carbendazim. If ventilation is poor, Begonia will be prone to aphids and thrips. Imidacloprid can be used to control them, and ventilation should be increased at ordinary times.
