I. Growth Habits of Rieger Begonia

Rieger begonia is mainly distributed in tropical and subtropical regions. It is a relatively cold-sensitive plant that prefers a warm, humid, semi-shaded environment. The minimum winter temperature must not fall below 15°C, so in winter it needs to be moved into a greenhouse or grown indoors.

II. Growing Methods for Rieger Begonia

The care of Rieger begonia needs to be adjusted according to the season. For example, in summer the amount of watering needs to be increased, while in winter, along with keeping it warm, the light factor must also be taken into account. Let us take a closer look below.

1. Watering

Watering should be carried out according to the specific conditions. For example, in summer when evaporation is high, more watering is needed, and it is best to water in the morning or evening; in winter it is best to water at noon, and the water temperature should not be too low, so as not to freeze and damage the plant. Note that watering should be decided based on the condition of the potting soil.

In daily management, air humidity can be increased by misting. Note that when misting, spray onto the leaf surfaces, not onto the flowers.

2. Fertilizing

Fertilizing is crucial to the growth of Rieger begonia. The fertilizing principle for Rieger begonia is to apply light but frequent feedings. Small Rieger begonia seedlings need some nitrogen fertilizer; as the plant gradually grows, the use of nitrogen fertilizer should be reduced, and more potassium and phosphorus fertilizers should be applied. Before flowering, more fertilizer is needed to ensure sufficient nutrients for blooming. A diluted foliar fertilizer can also be sprayed.

3. Temperature

In terms of temperature, the suitable growing temperature for Rieger begonia is 18°C to 22°C, and this temperature range tends toward the higher end. Therefore, Rieger begonia prefers a warm living environment, and attention must be paid to the colder winter. When growing Rieger begonia at home, winter insulation work needs to be done well, and the overwintering temperature for Rieger begonia should preferably not be lower than 15°C.

It should be noted that Rieger begonia is still flowering in winter, which means after being dried out it needs to receive sufficient light. The pot of Rieger begonia can be placed in a spot that receives more sunlight, such as a south-facing balcony or windowsill. Do not place it near a radiator. Also, in summer, temperature also needs attention; when the temperature is too high, cooling measures should be taken and shade provided in time.

4. Light

To promote the growth of Rieger begonia, it needs to receive sufficient sunlight. However, during the growth of Rieger begonia, light control needs to be done well. Shading in the early growth stage is essential. Secondly, Rieger begonia is a short-day plant and often needs artificial supplementary lighting, and before flowering it also needs dark treatment. How to do a good job of light control depends on the different climates of each region.
