Temperature

Crabapple is suitable for a relatively warm and humid climate, but it can also endure hot and low temperature. It has a good adaptability to temperature. The most suitable temperature for the growth of crabapple is about 18-25 ℃. If the temperature drops below zero in winter, the leaves of Begonia longwinged are easy to fall off, but they can continue to bloom when the temperature rises. It should be noted that if the temperature exceeds 35 ℃, shading treatment should be carried out immediately, and cooling should be carried out through water spraying, ventilation and other measures

Watering

Dragon winged Begonia likes to be wet. If the weather is too dry, its leaves are easy to curl up. Therefore, it is necessary to sprinkle water on the leaves from time to time to maintain a certain humidity. However, avoid ponding in the flowerpot, otherwise it will cause rotten roots; The pot soil should not be too dry. Lack of water will slow down the growth of Begonia and delay the flowering period

In spring, the growth of longwinged Begonia is very fast, and a large number of new branches will germinate and bloom. At this time, watering must be paid close attention to, and the longwinged Begonia cannot be short of water. In autumn, the temperature decreases slowly, and the water volume should be properly controlled. In winter, the growth of dragon winged Begonia will slowly stop. At this time, don't water more. Wait until the basin soil is dry

Fertilization

Dragon winged Begonia likes fertilizer. When planting, you can add some calcium superphosphate and organic fertilizer. Fertilization should be timely in the period of vigorous growth. It is best to apply more nitrogen fertilizer in the seedling period, which is conducive to the growth of flowers and seedlings. Potassium fertilizer should be mainly used in flowering period, once a week, a small amount and many times, so as to avoid excessive fertilization affecting growth. Fertilizer should be reduced as the temperature decreases in autumn until topdressing is no longer applied in winter

Illumination

Begonia longwinged has strong adaptability to light and can grow in almost any light environment. However, when the sun is too strong in summer, it needs to be properly shaded to slightly block 30% of the sun. Of course, it's best not to put the flowers indoors for a long time without sunshine, especially the seedlings of new species. Pay attention to gradually increase the duration of sunshine

Light has a great impact on the growth of Begonia longwinged. If the sunshine time is maintained at 8-10 hours every day, Begonia longwinged can bloom and grow horizontally half a month in advance; If you keep sunshine for a long time, the branches will grow upright

Pest control

Powdery mildew is a common disease of Begonia longwinged, which is caused by poor ventilation, high temperature and damp heat, and rotten roots caused by too wet soil. Spraying chlorothalonil or carbendazim once a week can effectively prevent powdery mildew. The common pests of the flower include aphids, whiteflies, red spiders, snails, etc., which should be prevented
