Specific measures

Temperature

Potted purple bamboo is best taken indoors for the winter. However, in order to make the plants slowly adapt to the rise of temperature, when the plants have just moved into the room, they can be ventilated regularly to avoid unnecessary damage caused by the sudden rise of temperature. For ground grown purple bamboo, the roots of the plant can be buried deeply, or covered with plastic film for the winter

Moisture

In winter, the temperature is low and the evaporation is small, so let's reduce the number of watering, do not or even less watering, and don't let the soil in the flowerpot be too dry. However, the humidity can be increased by spraying water indoors

Nutrients

The consumption of nutrients in winter is small. Some potassium fertilizer can be applied appropriately to increase their cold resistance. But be careful not to use too much

Ventilation

In winter, indoor doors and windows are generally closed, and the air is not circulating, which is very bad for plants. Therefore, open the doors and windows once or twice a day for 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 is inappropriate not to open it

Illumination

When talking about the growth habit of purple bamboo, we said that it is a light loving plant. Therefore, winter light is its necessity. Plants are usually exposed to light at noon when the sun is bright, but pay attention to receiving light evenly

Precautions

Purple bamboo is suitable for growing in places with sufficient light and relatively warm. It is generally 15 to 20 degrees and is not very cold resistant. In winter, growers in very cold areas in the North must help them survive the winter; However, special measures may not be taken in areas in the south where the temperature will not be too low in winter
