Breeding methods and precautions for Rieger Begonia in winter
Winter is approaching, does the Rieger Begonia on the windowsill always make you feel worried? This ornamental flower, known as the "Glass Beauty", requires special care during winter maintenance. Master these five core points so that your Rieger Begonia can not only survive the winter safely, but also continue to bloom in winter. Light management: Choose to place the magic effect of warm winter sun. Place the plants in a south-facing bay window or closed balcony, and use the soft direct light in winter to fill in light all day long. Rotating flowerpots adjust the light receiving surface every week to ensure even development of plant type. It is recommended to receive 4-6 hours of direct light every day for sunshine duration control, and turn on plant fill light for assistance on rainy days. Insufficient light can cause flower buds to fall off and yellow spots appear on leaves. Temperature control: Create a warm microclimate and manage indoor and outdoor temperature differences to maintain the golden temperature difference of 15℃ at night/20℃ during the day, and use thermometers to monitor in real time. Avoid placing plants near air conditioning outlets or radiators. Emergency cold protection measures When a cold current strikes, a temporary insulation cover can be made from transparent plastic bags, leaving ventilation holes and avoiding the strong noon light to prevent the temperature inside the bag from being too high. Water supply: The artistic watering opportunity of dry and wet cycles is judged using the bamboo stick detection method: Insert a 30-cm bamboo stick into the pot soil, stay for 10 minutes, and then pull it out. Water only when the tip is moist. In winter, the watering time is noon on sunny days. The water supply method is optimized to use warm water at 25℃ to slowly pour it through along the edge of the basin to avoid leaf area water. Combined with ceramsite paving can enhance breathability and prevent root rot. Nutritional management: Smart low-temperature fertilizer stop principle for winter fertilization When the environmental temperature is less than 15℃, fertilization is completely stopped, and the root system is in a dormant state and cannot absorb (S-Y) points. Blind fertilization will lead to salt accumulation. Fertilizer supplementation techniques for heating rooms at a constant temperature of 20℃ can replenish 3000 times diluted potassium dihydrogen phosphate once a month. It is better when combined with foliar spray. Environmental optimization: Details determine success or failure. Air circulation plan Open windows for ventilation for 30 minutes at noon every day, and use circulation fans to maintain air flow. Be careful to avoid direct cold air blowing, and install a transparent wind shield film in front of the window. Tips for humidity balance Place a humidifying water tray next to the flower pot, or regularly use an ultrasonic humidifier to maintain 50% ambient humidity. It is forbidden to spray water directly on flowers to prevent brown spot disease.
Through these five dimensions of refined management, your Rieger Begonia can not only survive the winter smoothly, but also accumulate energy to grow explosively in the spring of the following year. Remember that a stable environment is more important than surprise maintenance, so start creating your own winter maintenance plan for your green beauty now!
