The bamboo I kept in the vase is growing well, and many roots have been born. What should we do next?

Purple sand pots and plastic pots are suitable for cultivating rich bamboo, and outdoor pottery pots are better. It does not choose the soil very well, and grows best in loose and fertile sandy loam. Humus soil, vegetable garden soil and sand can be mixed and cultured at the ratio of 5∶4∶ 1, and if a small amount of broken eggshells infiltrate, they will grow more vigorously. Turn the pot and change the soil once a year in spring. When changing the soil, put a layer of broken hard plastic foam on the bottom of the basin, which is convenient for ventilation, drainage, root rot prevention and easy to take off the basin. Water and fertilizer management: Fu Guizhu likes wet and fat, but indoor potted plants should control water and deduct fertilizer to make them grow slowly and improve their ornamental value. During the growing period, according to the change of seasonal climate, when the soil is dry, water should be poured every 2 ~ 5 days to keep the soil slightly wet and not waterlogged. Too wet soil is easy to grow white, and too dry leaves are easy to dry. Water should be sprayed on leaves frequently to increase the air humidity in the small environment, which is beneficial to their growth. Insist on applying thin fertilizer frequently, and apply a small amount of NPK compound fertilizer every 15 ~ 20 days. Excessive or single application of nitrogen fertilizer is easy to grow in vain. No fertilization in winter, less watering. Temperature and illumination Fu Guizhu is native to Madagascar Island in the western Indian Ocean. Like warm, the optimum growth temperature is 18℃ to 25℃. It is not cold-tolerant. When the minimum temperature drops to 5℃, it should be wintered indoors, and the room temperature should be kept above 5℃. It likes an environment with plenty of scattered light. Summer and early autumn should not be exposed to the hot sun. It can be placed from late autumn to the next spring, within 2 meters from the window, where there is enough direct or scattered light. If it is cloudy, its leaves will be colored. After many years of planting, the ratio of plant height to flowerpot size is out of balance, which affects the appearance. In May and June, it can be cut to 15 cm from the basin soil 10 cm. After cutting, the lower base will sprout new branches, and the upper stem can be used for cutting propagation. From May to September, rich and precious bamboos raised in water in bottles, or newly cut and rooted rich and precious bamboos, can be planted directly in the soil. Cut the rootless ones into 15 cm to 20 cm long, cut off the leaf springs of the buried part, then apply sulfur powder or plant ash on the incision, insert them into the vegetable culture soil, place them in the shade, spray water frequently to keep them moist, and move them to a place with sufficient scattered light for maintenance after they grow new leaves.
