1、 Winter method

1. Adjust the temperature: Fortune trees don't like low temperature, so they must adjust the temperature above 10 ℃ during the winter. If the temperature is too low, there will be freezing injury, and the leaves will show the symptoms of yellowing or wilting. It's not easy to spend the winter in the cold air outside

2. Control watering: less water is necessary for winter maintenance. It grows slowly in cold weather and has low requirements for water. If you still pour too much water, it is not only easy to rot roots, but also easy to be frostbitten. Winter is usually watered once a month. If necessary, spray water on the leaves

3. In winter, the plant is not ventilated properly, but it can not be ventilated in a stuffy environment. Especially in heating and air-conditioned rooms, more windows should be opened. As long as the cold wind is not blowing directly, it will not be frozen

4. Full exposure to light: the sunlight is very weak during winter. In order not to affect the growth of plants, we should allow sufficient exposure to light in the sun. More sunlight can not only promote photosynthesis, but also increase temperature to a certain extent

2、 Cause of yellowing

There are many reasons for the yellowing of the leaves of fortune tree. If you water too much during daily maintenance, the root system will rot, and the leaves will turn yellow or even fall. The watering frequency should be controlled. In case of long-term drought, the plant leaves will turn yellow if they can't absorb water, so they should be watered in time. There is also a lack of fertilizer for a long time. Lack of nutrition will lead to yellow leaves. Fertilization should be reasonable. Fertilization can be applied once every half a month during the growth period
