How to care for Rieger begonias in winter to ensure they survive the cold season
This article provides knowledge on how to care for Rieger begonias in winter to help them survive. Let's take a look at how to care for Rieger begonias in winter and ensure their safe passage through the cold season.
1. Cold proofing and insulation Rieger begonias are very sensitive to cold, so it is necessary to take measures to keep them warm in winter. When the temperature drops below 20 degrees Celsius, they should be moved indoors and placed in a sunny location, such as a south-facing balcony or windowsill, where they can receive plenty of light to continue photosynthesis and prepare for growth and flowering. This also helps enhance their cold resistance.
2. Reducing watering In winter, it is important to control the watering of Rieger begonias. Since they are usually in a dormant state during this period, their water requirements are minimal, and watering can be reduced accordingly. When it's cold in winter, you can wait until the potting soil is completely dry before watering. If the indoor temperature is around 20-25 degrees Celsius, watering can be done once a week. If the temperature is between 10-15 degrees Celsius, watering can be reduced to once every 10 days. When watering, it is best to do so at noon, ensuring that the temperature of the water is not too different from that of the potting soil to avoid large temperature differences affecting the plant's growth. Water should be poured slowly around the edge of the pot to avoid splashing onto the leaves.
3. Stop fertilizing In winter, the growth rate of Rieger begonias is relatively slow, so fertilizing can be stopped. It is also important to maintain proper ventilation in the surrounding environment to avoid being in a stuffy environment, which can easily lead to problems. However, if the temperature is suitable and the plant continues to bloom, phosphorus and potassium fertilizer or foliar fertilizer can be applied before blooming to ensure sufficient nutrients for flowering.
4. More sunlight Rieger begonias prefer a semi-shaded environment and are sensitive to direct sunlight, which can cause the leaves to wilt and scorch in summer. They should be moved to a cool, well-ventilated place for care. In autumn and winter, when sunlight is weaker, increasing exposure to light can help the plants grow more vigorously and is beneficial for bud formation and flowering.
The above information provides specific details on how to care for Rieger begonias in winter to ensure their safe passage through the cold season, for everyone's reference and application.
