Potted purple bamboo is best taken indoors for winter. However, in order to make the plant slowly adapt to the rise of temperature, when the plant just moved into the room, it can be regularly ventilated to avoid unnecessary damage caused by the sudden rise of temperature. For the ground planting of Zizhu, you can bury the root of the plant, or cover it with plastic film for winter.
In winter, the temperature is low and the evaporation is small, so reduce the frequency of watering, do not water or even less, and do not let the soil in the flowerpot be too dry. However, the indoor plants can be properly sprinkled around to increase humidity.
In winter, the consumption of nutrients is small. Some potassium fertilizer can be applied properly to increase their cold resistance. However, we should be careful not to use too much
In winter, the doors and windows are usually closed, the air is not circulating, which is very bad for plants. So, open the doors and windows once or twice a day, about half an hour each time. If the temperature is too low, it can be opened once a day, and the time will be reduced accordingly. However, it's not appropriate not to open
When talking about the growth habits of Zizhu, we said that it is a light loving plant. Therefore, the light in winter is a necessity. Generally at noon when the sun is shining, let the plants receive the light, but pay attention to receive the light evenly.
Zizhu is suitable for growing in a warm place with sufficient light, generally 15 to 20 degrees, not very cold resistant. In winter, the growers in the very cold areas in the North must help them to survive the winter, while in the areas in the south where the winter temperature is not too low, special measures can not be taken
