Potted dragon spit beads, generally every 1 to 2 years to change the basin, change the basin time in early spring or after the flower. When changing the basin, first use the broken tiles to pad the drain hole, then put a small amount of bone meal as the base fertilizer, and then put in the new culture soil (4 parts of rotten soil, 4 parts of garden soil, 2 parts of sand soil), plant the plants, and leave 2-3cm along the mouth for fertilization and watering. After the basin is replaced, water shall be poured into the basin, and the seedlings shall be slowly planted in the shade, and then moved to the sunny place for maintenance.
Watering: longtuzhu is sensitive to water. During the growth period of stem and leaf, the salt soil should be kept moist, but the watering should not be excessive, and the water volume is too large, resulting in long vines without flowering, or even yellow leaves, withering, root rot and death. In the high temperature season in summer, the water should be fully watered and the shade should be appropriate. In winter, we should reduce watering and make it dormant so as to survive safely.
Fertilization: fertilization should not be excessive. In the flowering season, apply fertilizer and water to the rotten pancakes once every 7-10 days, and apply fertilizer 3-4 times in succession. If there is yellow phenomenon in the cultivation process of longtuzhu, it can be combined with Topdressing and 0.2% ferrous sulfate, which can make the leaves gradually turn yellow to green.
Temperature: it is not suitable to put it too long in the dark. If the temperature is above 21 ℃ for more than 24 hours, flowers will fall.
Light: the Dragon spits the bead winter to need the light to be sufficient, the summer weather too hot time suitable shade, otherwise the leaf is yellow. When the light is insufficient, it will cause tendril growth and no flowering. Flower bud differentiation is not affected by photoperiod, but strong light can promote flower bud differentiation and development.
Longtuzhu can be propagated by sowing and cutting.
