1、 Environment

The safe tree should be placed in an environment with bright light, good ventilation, high enough humidity and appropriate temperature. Generally speaking, it requires the growth temperature to be above 5 degrees, and there will be freezing damage below 5 degrees. The temperature range between 15 degrees and 25 degrees is the temperature range for the rapid growth of safe tree

2、 Moisture

Ping An trees do not require too much water, and the soil is suitable to be slightly dry; But the requirement of air humidity is very high, so we should spray and spray it regularly. In the case of general production, when the relative humidity of the environment reaches 80%, it will grow very vigorous. After autumn, phosphorus fertilizer should be added once or twice to improve its cold resistance. Fertilization should be stopped in winter

3、 Fertilization

Ping An tree doesn't have very high requirements for fertilizer, so we usually give it thin fertilizer and water every ten days to half a month in the growing season

4、 Precautions

When it is maintained in the north, if the soil is alkaline and the irrigation water is alkaline, it will turn yellow. At this time, we can improve the acidity and alkalinity of the soil by adding edible vinegar or alum fertilizer water to the water to promote its green and lush growth
