According to the laws of nature, potted plants should fall in the cold winter leaves and fall behind. The flowers blossom in spring and spring. Things can be quite the opposite, there are many people's potted plants, winter green leaves red, but in the spring it leaves yellow flowers, especially Milan, smiling, camellia, azaleas and other famous flowers, not only fall flowers, leaves and other phenomena. Even some whole plants die. What are the reasons? The factors are many, but the main points are as follows. Prematurely move the potted plants outdoors to the sun. Due to the low temperature in the room during the night, the temperature suddenly changed and the root system was injured. Too much water in early spring. Especially in the northern regions, after the heating is turned off, the indoor temperature is low, the plant's ability to absorb water is poor, and water is too much, which makes it easy to rot the root system. Applying concentrated fertilizer in early spring, especially using unfermented fresh milk, hemp sauce, or liquid fertilizer containing too much fat, is the third cause of pot-burning. In addition, the potted plants in the winter receive less sunlight and their branches are tender and tender. If they leave the house prematurely in the early spring and are attacked by the cold wind, they will also be harmed. Spring is the golden season for changing pots. At this time, the flowers are in a dormant stage, and the wounds are easily healed after changing basins, and the flowers can get rich nutrients, which lays a good foundation for the whole year's growth. Vegetative flowers and plants grow rapidly due to short growth cycle and should be changed once a year; woody flowers such as plum, waxberry, pomegranate, rose, etc., can be changed once a year; pine, cypress and bamboo evergreen flowers are slow growing. It can be changed once every 2-3 years or 4 years. Large bonsai or stump bonsai, do not have to increase the scale of the basin year by year, in the original basin for a ring of soil or root repair, change the basin every other time again. Generally, new pots should be soaked and soaked in water before they can be used. If the pots are soaked in fertilizer water, it is more ideal. If you still use the old pot, you should wash it to prevent the original bacteria in the pot from infecting the newly changed soil. When changing pots, the pelvic floor drainage holes are first covered with tiles, and then a layer of culture soil is laid on the bottom of the pots. When changing pots, remove 1/4-1/3 of the old soil. After removing the old roots, put them into the pots. Watering: Basin soil should be compacted and the new soil should be added 2-3 cm away from the basin. The first pass of water should be thorough, then, in a cool place, about a week later, then placed in the sun.
