The maintenance of plants in winter is a big problem. If you are not careful, you may freeze to death. For different kinds of plants with different living habits, the maintenance methods in winter will be different. Here are some of the information we collated for readers' reference.
1、 First of all, we should do a good job in keeping warm and freezing for foliage plants
In order to keep the foliage plants of tropical and subtropical regions green and full of life in winter, we should first do a good job in keeping warm and freezing.
Winter watching plants
The foliage plants whose overwintering temperature can not be lower than 5 ℃, such as asparagus, ivy, Liriodendron, star anise, Ruyi, konjac, cold water flower, palm flower, etc., have certain cold resistance, can safely overwinter in general cold proof facilities, and can also enter single-layer plastic shed or general greenhouse. For the foliage plants whose wintering temperature cannot be lower than 8 ℃, such as swallow's paw, tiger ear grass, jade emperor, fish tail anemone, Buddha belly bamboo, red Nest Fern, etc., when it is coldest, a layer of plastic film shall be added in the shed or indoor.
The foliage plants whose overwintering temperature can not be lower than 10 ℃, such as Wenzhu, Chlorophytum, Douban green, huayetaro, hongyuzhutaro, lvluo, xianglongxueshu, nanyangshan, Fuguizhu, etc., shall be placed in a two-layer plastic shed or a greenhouse covered with a plastic film as soon as they enter winter. The most delicate is the foliage plants whose winter temperature can not be lower than 15 ℃, such as horseradish, variable leaf wood, white netted grass, fortune tree, Boston fern, etc., which are best placed in the greenhouse with heating equipment. If there is no heating condition, they can be placed in the second layer of plastic greenhouse. The southern maintenance should be between 3:00 p.m. and 9:00 a.m. on the top of the foliage plants, covered with a plastic film It will be opened at 9 o'clock the next day. 2、 Succulent plants, reduce the amount and frequency of watering
With the advent of winter, the growth of succulent plants becomes slow, and some summer species even enter into dormancy. Most of them have limited ability to endure the low temperature, so it's urgent to get a sunny window. In addition, because of the weak transpiration of plants and the slow evaporation of soil water in winter, the amount and frequency of watering must be reduced.
Succulent plants winter
Generally speaking, no matter in the north or the south, if the temperature can be kept above 5 ℃ in winter, the meat can continue to be placed outdoors. Occasionally, it will fall below 0 ℃. Most of the leaves of the meat are water, which will slowly freeze. If the temperature returns to 5 ℃ or above after about 0 ℃ for two consecutive days, the problem is not serious. Just stop watering immediately after paying attention to the temperature below 5 ℃. The winter in the south is often accompanied by rainy season, so the meat placed outdoors should be protected from the rain, and the frequency and quantity of watering should be reduced.
In addition, ventilation is also an important condition for good growth of succulent. If you are indoors, you can turn on the fan to blow in a warm noon. In the case of sufficient sunshine at noon, it is easy to reach 20 ℃. If you feel the indoor environment is stuffy, you can use a fan to blow it.
It is also necessary to note that in winter, it is better not to buy more meat online, because it is easy to freeze to death and frostbite during express transportation, and the meat after frostbite is recovered very slowly. 3、 Hydroponics plants should keep warm and moist in winter
5 ℃ is the lowest temperature that most plants can bear, and many plants will enter the dormancy period in winter. However, under the climate conditions of Hangzhou City, most hydroponic flowers can survive the winter safely, and the main problem of its winter maintenance is "keeping warm and moisturizing".
Hydroponics for winter
First of all, hydroponic plants should be placed in leeward position as far as possible to avoid direct north wind. In the daytime, it should be placed in the direction with sufficient sunlight or bright scattered light, such as the room facing south or the window side, to receive sunlight as much as possible, but it should avoid direct sunlight outside the room for a long time, and it should also avoid the air leakage of the window, so as to prevent cold wind from attacking and freezing.
If the indoor temperature is less than 5 ℃ in the evening, the whole plant must be covered with a thick transparent plastic bag from top to bottom to keep warm and moisture. 2-3 small holes shall be opened on the plastic bag to facilitate ventilation, so as to ensure that it can survive the cold period smoothly.
Because the metabolism of plants is very slow in winter, which requires little water and fertilizer, in addition to reducing the water level to 3 / 1 of the root system, it is also necessary to stop using nutrient water, otherwise it is very easy to rot roots and leaves, or even the whole plant dies. Pay attention to the temperature difference of water when changing water. Fresh tap water should be placed indoors or in the sun for a day. It can be used only after chlorine escapes and the water temperature is the same as the room temperature. If the water temperature is more than 10 ℃ different from the room temperature, it is easy to damage roots and leaves.
In addition, air drying is easy to cause dry tips or scorched edges of flower leaves that like air humidity. Therefore, during winter, spray branches and leaves with water close to room temperature to increase air humidity.
Take good care of your flowers and plants. Let them live a safe winter. They will give you an amazing spring and summer.
