Epiphyllum grows and develops in stages in a year. Flowering from spring to July and August is the most vigorous season for its vegetative growth and reproductive growth. At this time, we must create conditions for its growth. Long Xia Hou, put it outdoors in a cool environment to avoid exposure to the sun. Keep the epiphyllum on the balcony. Don't put it directly on the cement board. It's better to put a wooden board or keep warm and build a arbor on it. If it is placed outdoors unconditionally, it can also be placed in a ventilated place indoors. With the increase of temperature, the supply of fertilizer and water gradually increases. However, from the end of August to the appearance of flower buds, it is necessary to control fertilizer and water to dry the soil, increase pesticide spraying and maintain high air humidity to promote the formation of flower buds. When the bud appears, the supply of fertilizer and water should be sufficient, and phosphate fertilizer should be applied in time to promote the colorful flowers. After flowering, it has a short dormant period. At this time, watering should be controlled, fertilization should be stopped, and too much soil should be kept in the basin. Plants should continue to grow after beginning of autumn. In order to rejuvenate plants, mature organic fertilizers should be applied. During the winter dormancy period, keep the basin soil dry and put it in a sunny place, and the room temperature is not lower than 10℃ for safe wintering.
