What is meant by "not going out in spring" and "not entering in winter"?
Let me tell you about the explanation of family flower cultivation, what is meant by "not going out in spring" and "not entering in winter"? The following is a detailed introduction.
People have summarized two experiences in the long-term practice of growing flowers: one is called "not going out in spring"; the other is called "not entering in winter". "Not going out in spring" means not to rush to take the flowers out of the room in early spring. Because the weather in the north is changeable in spring, it often blows dry winds, and cold currents strike from time to time. If you go out too early, it is easy to suffer from drought winds, and the tender buds and leaves are often blown burnt; at the same time, it is also prone to late frost damage, causing sudden defoliation, and in severe cases, the whole plant can die, so it is not suitable to go out too early.
In most parts of the north, the time for flowers to go out of the room in winter is between Qingming and the beginning of summer.
Flowers must go through a period of adaptation before going out of the room. Usually, about ten days before the flowers go out of the room, open the windows for ventilation at noon, gradually endure the training, and then go out, so that they can gradually adapt to the external temperature. After going out, if you encounter late frosts or strong winds, you still need to move them into the room in time, and wait for the weather to improve before moving them out again. "Not entering in winter" means that when it is cold, if there is no frost, for most flowers, do not rush to move the potted flowers into the room.
Because at this time, the temperature keeps changing, sometimes cold and sometimes hot. If you move the flowers into the room too early, it is not good for their growth and development. At this time, you should place the flowers in a windless and sunny place to let them go through a period of low-temperature training, which is beneficial for most flowers. However, since different flowers have different temperature requirements, the time to enter the room varies from early to late and cannot be uniform.
Usually, it is suitable for chrysanthemums, poinsettias, hibiscus, hanging bells, and cacti to enter the room when the temperature drops to about 10 degrees Celsius. For jasmine,米兰, camellias, kumquat, and evergreen, it is better to enter the room when the temperature drops to about 5 degrees Celsius. Potted grapes, roses, and figs need to be frozen at -5 degrees Celsius for a period of time to induce dormancy, and then moved into a cold room (about 0 degrees Celsius) for storage. For newly entered flowers, attention should be paid to ventilation.
The above explanation about what is meant by "not going out in spring" and "not entering in winter" hopes to bring a little help to your life!
