1、 Cut off dead branches and leaves

After the potted ginger lotus withers, the residual flowers and dead branches should be cut off in time, so that the nutrients can be fully supplied to the plant and the bottom of the rhizome can slowly grow into a ball shape. The temperature is low in winter. After cutting off the residual leaves of ginger and lotus, put them into the environment with indoor temperature above 10 ℃. You can spend the winter safely. The ginger lotus planted in the green space is dug out in the late autumn, wrapped with peat ash and stored indoors at a temperature above 10 ℃. It can be replanted in the green space in the spring of the next year

2、 Proper lighting

Potted ginger lotus in dormant period should also absorb sunlight properly. When the temperature is relatively high around noon and there is plenty of sunshine, the ginger lotus should be moved to a place where the sun can shine to absorb the sun. You can also move outdoors for light

3、 Proper ventilation

During the dormancy period, ginger lotus cultivated indoors should be ventilated every few days. Windows can be opened for ventilation at noon when the weather is good and the temperature is high. Do not put the ginger lotus in the vent during ventilation, otherwise it will affect its growth and development. It can also be placed outdoors for ventilation

4、 Storage of bulb

At the end of November, the ginger lotus will stop growing and the bulb will enter the dormancy period. The ball root must be dug out, wrapped with wood dust and placed in a plastic bag. Store in a humid and ventilated environment

5、 Suitable temperature

Ginger lotus is a tropical plant, suitable for high temperature environment. When planting potted ginger lotus indoors in winter, keep the indoor temperature above 10 ℃. Below 10 ℃, ginger and lotus will suffer frostbite or rotten roots

After the potted ginger lotus enters the dormancy period, fertilization should be stopped and watering should be reduced appropriately

Before replanting in the second year, the bulbous roots must sprout in an environment of about 30 ℃, and can be replanted after budding. It usually blooms in two to three months
