How do indoor flowers in the north survive the winter? How do indoor plants prepare for wintering before entering the room?

The subject's question is very good The management and maintenance of potted flowers before and after entering the house in winter is indeed an important issue, because whether the management measures are appropriate is directly related to the survival of potted plants, and it is really difficult to give a satisfactory answer. There are thousands of potted flowers of different kinds and characteristics. The so-called northern region, the phenological gap is very large, and the indoor environment is different. Therefore, Baihua Zatan can only take Shandong as an example and share some sexual things with flower friends.

In order to facilitate reading and answer questions in reverse order, share the preparation questions before potted plants enter the room.

Take preventive measures. If it doesn't rain, you should be prepared. Similarly, if winter does not arrive, you should be prepared before entering the room. When is the appropriate time to advance? It is best to start after autumn, end the high temperature in summer and turn cold. Most potted flowers will enter the second growth peak. During this period, it is necessary to give sufficient light and increase the management of water and fertilizer to promote the healthy growth of plants and enhance their cold resistance.

In the northern region, the first frost in the 24 solar terms is the key solar term for plant growth. Generally speaking, after the first frost, most plants basically stop growing. Therefore, potted flowers that have been planted in the first frost need to reduce the supply of fertilizer and water. Trim, trim and change pots. However, according to the normal climate characteristics, the first frost, a common potted flower, entered the room a little early. Let plants grow at low temperature at night in natural environment, which is beneficial to indoor overwintering growth. Potted herbaceous flowers usually enter the room before beginning of winter. Woody flowers and trees should be put off until around the heavy snow.

The best place to maintain potted flowers and trees in winter should be the sealed balcony facing south. According to my records of measuring the winter temperature of the balcony for many years, the temperature of the sealed balcony can be kept above 5 degrees even if it is MINUS 24 degrees outside. Except for southern flowers such as Milan, the temperature of 5 degrees will not cause growth damage to plants. If the front window is covered with plastic film, the temperature can reach about 18 degrees at night and above 18 degrees during the day. Such a temperature environment is exactly what potted plants such as Clivia, Orchid, Cyclamen, and Changsheng need to grow. Therefore, potted flowers overwinter on the balcony, as long as watering and fertilization are well controlled, there is no need for too many management measures.

The so-called control of fertilizer and water means less watering, less fertilization or even no fertilization. Beginners of flower cultivation must not introduce information mechanically, but follow the instructions of adding water and fertilizer before flowering and topdressing once every few days in potted plants. According to my planting practice, in the low temperature and high temperature environment, the absorption capacity and demand of plants for fertilizers are not high. In particular, potted plants from the flower market do not need topdressing at all and bloom without applying any fertilizer. On the contrary, it will cause poor plant growth and even death.

As for indoor potted flowers, the problems that need to be paid attention to are nothing more than those platitudes, such as light, temperature, humidity and ventilation. Some well-known problems are not repeated here. Pick a few questions and share them.

The indoor space is limited and the light is limited. Therefore, in order to ensure the illumination of potted plants, they need to be placed in an orderly manner. In principle, flowers need more light in winter, foliage plants need less light, potted plants with evergreen seasons have more light, and deciduous potted plants will survive the winter safely even if the light is insufficient in a short time.

The temperature and overwintering temperature of potted plants in heating rooms need to be treated differently. Most southern flowers and trees need higher temperature, while local flowers and trees that go into dormancy in winter need lower temperature. Avoid excessive temperature, excessive temperature, insufficient dormancy of plants and poor growth in the coming year.

Humidity. The general principle is that dry soil and wet leaves are the most suitable. Any indoor potted plants should keep the soil slightly dry in winter. For leaves, a moist growing environment is needed.

Ventilation is the key problem of potted plant management in winter. The indoor environment is closed, the number of potted plants is large, and the air circulation is insufficient, which will seriously affect the breathing of plants. Plants can't express dyspnea in words, but their growth can have obvious characteristics. If the potted leaves turn yellow before they are old, it means that there is not enough oxygen in the air. In this way, the south window will be opened for about half an hour at noon. At the same time, it should be noted that cold air should not be blown to the potted plants. Especially in Milan, once frozen by the cold wind, the leaves will definitely fall off.
