How to cultivate high-quality Rieger begonias
Today, the editor will introduce the topic of growing Rieger begonias at home. How to cultivate high-quality Rieger begonias? Let's share the detailed content next.
Guo Qizhi from the Forestry Bureau of Shunyi District, Beijing, answers: To cultivate high-quality Rieger begonias, attention should be paid to the following aspects:
Temperature The suitable temperature for Rieger begonias to grow is between 15°C and 22°C. Below 10°C, the plant will stop growing, and above 28°C, it will grow slowly. To achieve the best growth state, the night temperature should be maintained around 20°C, and plants are prone to elongation above 24°C.
Light Rieger begonias prefer scattered light and dislike direct strong light. Different growth stages have different requirements for light. In the seedling stage, the light should be around 15,000 lux, and then gradually increased to 25,000 lux. Producers can adjust the light intensity according to the flowering situation.
Water For Rieger begonias with fleshy rhizomes, water (G-Y) is very important. Insufficient water (G-Y) will affect the plant's growth, while excessive water can lead to rhizome diseases and soft stems. Watering should adhere to the principle of watering when dry and keeping the leaves dry.
Humidity In the early stage of growth, Rieger begonias require higher humidity, with a relative humidity of 80% to 85%. After the flower buds form, the relative humidity should be gradually reduced to 50% to 60%. When the relative humidity is between 70% and 80%, attention should be paid to air circulation to prevent powdery mildew and gray mold.
Fertilization and Water Management Adhere to the principle of applying thin fertilization frequently. For seedlings, apply a dilute liquid fertilizer mainly containing nitrogen. As the plant grows, adjust the content of nitrogen, phosphorus, and potassium as needed. In the medium seedling stage, apply balanced fertilization, and later increase phosphorus and potassium fertilizers while reducing nitrogen fertilizers. During the entire growth process, appropriate foliar fertilization should be carried out by evenly spraying the fertilizer solution on both sides of the leaves.
