How to raise a rich tree in winter? Please give instructions that the rich tree is evergreen and likes the hot and humid climate. The lowest temperature in winter should be 15 ℃-18 ℃. Below this temperature, the leaves are easy to turn yellow and fall off. If the indoor temperature is high, it takes 3-5 days to pour water thoroughly, that is, you can see a small amount of water seeping out from the bottom of the basin. Check whether there is a lack of water, you can use your fingers to poke away about one centimeter of flower soil on the surface. If the soil is dry, you need to replenish it in time, and if the soil is still wet, you do not need to water it. In winter, the rich tree will appear depressed, and many leaves will gradually turn yellow and fall off, making them sick. This is due to the high indoor temperature and low humidity in winter, plants will protect themselves, so that the leaves reduce water evaporation, resulting in wilting. Therefore, indoor humidification should be appropriate. If the plant has grown up, the original flowerpot can not meet its growth, you can replace a larger flowerpot at an appropriate time. The rich tree generally changes the flowerpot once every 1-2 years. When changing the pot, we should pay attention to protecting the soil ball at the root. After filling in the new soil in the new pot, we should compact it and pour it thoroughly. Finally, leave it in a cool place and let the plant gradually receive sunlight a week later.
