Dragonfinch is suitable for warm and humid climates, but can also tolerate heat and low temperatures, and has a good adaptability to temperature, and the most suitable temperature for the growth of dragonfidel begonias is about 18-25 ° C. If the temperature drops below zero in winter, the leaves of the dragon-wing begonia will easily fall off, but when the temperature rises, it can continue to flower. It should be noted that if the temperature exceeds 35 ° C, it is necessary to carry out shading treatment immediately, and cool down by spraying water, ventilation and other measures.
Dragon-winged begonias like to be wet, and if the weather is too dry, the leaves are easy to curl up, so it is necessary to sprinkle water on the leaves from time to time to maintain a certain humidity. However, water should not accumulate in the pot, otherwise it will cause rotten roots; the pot soil cannot be too dry, and the lack of water will slow down the growth of begonias and delay the flowering period. In the spring, the growth of dragon-winged begonias is very fast, and a large number of new branches and flowers will germinate, and watering must be tightened at this time, and the watering of dragon-winged begonias cannot be allowed to appear in a state of water shortage. Entering the autumn, the temperature slowly decreases, and the amount of water should be properly controlled. In the winter, the growth of dragon-winged begonias will slowly stop, at this time do not water more, wait until the potting soil is dry before watering.
Dragon's fin begonias like fertilizers, and some superphosphate and organic fertilizers can be added when planting. Fertilization should be timely during the period of vigorous growth, and it is best to apply more nitrogen fertilizer during the seedling period to help the growth of flower seedlings. The flowering period needs to be based on potassium-containing fertilizer, once a week, a small number of times, so as not to affect the growth of too much fertilizer. In autumn, the fertilizer should be reduced as the temperature decreases, until the winter is no longer topdressed.
Dragon-winged begonias are very adaptable to light, and can grow in almost any light environment. However, when the summer sun is too strong, it is necessary to carry out appropriate shading treatment, and slightly block 30% of the sunlight. Of course, it is best not to leave the flowers indoors for a long time without seeing the sun, especially the newly planted seedlings, and pay attention to gradually increasing the length of the sun. Light has a greater impact on the growth of dragon wing begonias, if the daily sunshine time is maintained at 8-10 hours, the dragon wing begonias can flower half a month in advance, the branches are long; if you keep the sun for a long time, the branches will grow upright.
