How to grow Rieger Begonia

temperature

In terms of temperature, the suitable cultivation temperature for Begonia is 18℃～22℃, which is relatively high in the temperature range. Therefore, it likes a warm living environment, but needs to pay attention to the lower temperatures in winter. When raising them at home, you need to do a good job of keeping warm in winter, and the wintering temperature should not be lower than 15℃.

It should be noted that the Begonia will still bloom in winter, so it needs to be kept dry so that it can get sufficient light. The pot of Begonia can be placed in a place where it can get more sunlight, such as a south-facing balcony or windowsill. Do not place near a heater. Also in the summer, you need to pay attention to the temperature. When the temperature is too high, you need to take cooling measures and provide shade in time.

Watering

Watering should be carried out according to specific circumstances. For example, in the summer when evaporation is high, you need to water more often, preferably in the morning or evening; in the winter, it is best to water at noon, and the water temperature should not be too low to avoid frostbite the plants. Note that watering should be determined according to the condition of the potting soil.

In daily management, you can increase the air humidity by spraying water. Be careful to spray the water on the leaves, not on the flowers.

illumination

In order to promote the growth of Rieger Begonia, it needs to be exposed to sufficient sunlight. However, during the growth of Begonia, light control needs to be done well. Shading is essential in the early growth stages. Secondly, Begonia is a short-day plant that often requires artificial lighting and dark treatment before flowering. How to control the light depends on the different climates in each region.

Fertilization

Fertilization is also the key to its growth. The principle of fertilizing Rieger Begonia is to apply fertilizer thinly and frequently.

Young seedlings of Begonia need some nitrogen fertilizer. As the plants grow bigger, you should reduce the use of nitrogen fertilizer and apply more potassium fertilizer and phosphorus fertilizer. Before flowering, you need to apply more fertilizer to ensure sufficient nutrients for flowering. You can also spray some foliar fertilizer that is not too concentrated.
