The flower room has been used to the warm and windless environment. It is difficult to adapt to the cold wind when you leave the room.
1. Increase the ventilation and light transmission in the first half of the month before leaving the room, open the window for ventilation in the daytime, close the window at night, keep the room temperature between 6 ℃ and 12 ℃, and do so for 2 weeks..
2. After two or two weeks, move out of the room in the daytime. If the temperature is too low at night, move back to the room, and move out again in the morning the next day, so that it can be directly put out of the room in 7-10 days..
All kinds of flowers are different in sensitivity to temperature and cold tolerance, so potted flowers should be divided into different rooms.
1. Flowers with strong cold resistance can leave the room at about 10 ℃. Such as two-color jasmine, German Primula, longevity flower, he's Phoenix, Golden Lotus, Lingjian lotus, camellia, chamei, azalea, penglaisong, etc.
2. Some flowers originated from the tropics with poor cold resistance should be in the south for several days before and after the Qing Dynasty and the Ming Dynasty, and in the north for several days before and after the rain. For flowers that do not know the cold resistance, it is better to stay late than early. For example, jasmine, Aglaia odorata, Fusang, poinsettia, Pearl Orchid, colorful leaf grass, pothos, etc., it is advisable to leave the room later.
If the flowers that are afraid of sunshine, like shade and like half shade are exposed to sunlight above 20 ℃ when they leave the room, they may cause sunburn, leaf wilting, wilting, yellowness and even death of the whole plant.
1. The best choice for potted flowers is cloudy weather, such as sunny days, such as Cyclamen, Daphne, New Guinea Impatiens, Zhulan and other flowers that are afraid of sunshine. The sun is strong at noon and needs to be shaded.
2. For example, pothos, Rhododendron, Chunyu, Wenzhu, Junzilan, etc., should be placed in a place where direct light can be seen in the morning or evening, and where the sun can be avoided around noon.
In the spring of the Yangtze River Basin, it is easy to appear cold or hail, which has a great influence on the newly sprouted flowers and seeded seedlings.
Therefore, in case of cold spring or hail (pay attention to weather forecast) after leaving the room, you can move the fresh flowers back to the room or cover them with plastic film.

Potted flower a whole winter has been used to the dry soil, just woke up from sleep in early spring, the root water absorption function is gradually recovering, at this time, such as pouring water, the soil is too wet to cause rotten roots.
1. The potted flower should spray water to the stems and leaves more when it comes out of the room, still less water, and the potted soil is slightly wetter than in winter.
2. The water temperature for watering should be about 15 ℃, and the time should be at noon. From early spring to late spring, with the increase of temperature and the growth of plants, the amount of watering can be increased gradually to make it gradually adapt to the needs of growth.

At the time of first leaving the room, the function of absorbing fertilizer at the root of potted flower is still recovering. At this time, ferocious application of fertilizer is harmful and unhelpful, especially the application of concentrated fertilizer, often leads to the death of burning the root.
1. When the potted flower is just out of the room, it's better to let it grow naturally. It's not busy fertilizing in 1-23 weeks, and then fertilizing according to the situation after it adapts to the environment.
2. For foliage plants and flowers blooming in summer and autumn, first apply light liquid nitrogen fertilizer to promote the growth of their branches and leaves. With the increase of temperature and the growth of plants, gradually increase the amount of fertilizer, and change the application of nitrogen, phosphorus and potassium compound fertilizer.
3. For flowers blooming in spring and early summer, apply nitrogen, phosphorus and potassium compound fertilizer at the beginning, from thin to thick, from less to more, and stop applying when the flower bud is about to bloom.
Potted flowers, especially perennial herbaceous flowers, after a year's growth, the nutrients in the potted soil have been basically exhausted, and the root is full of the basin wall, forming a root circle layer, watering and fertilization are often from the root circle layer directly under the basin bottom, but the basin soil is difficult to absorb.
1. The flowers that bloom in early spring should be turned over before entering the room at the end of autumn and the beginning of winter, while other flowers should be turned over when leaving the room in spring.
2. Woody flowers can be turned over in the early spring for soil replacement once in two or three years. Except for a few flowers such as camellia, which can be changed into soil with bare roots, most other flowers should keep 1 /2 to 1 /3 of the old soil, and properly trim the old roots to promote the development of new roots.

When we move flowers out, we must pay more attention!
