Now the housing conditions of the residents have been improved. The enclosed balcony is very beneficial for the flowerpot to survive the winter. If there is no enclosed balcony, the potted flowers should enter the room at night. Some potted flowers that are especially afraid of cold, such as tropical orchid, pineapple, poinsettia, red palm, Aglaia odorata, Christmas Cactus, poinsettia, guayeju, zhudinghong, etc., should not be less than 10 ℃ at night.
Jasmine, four seasons Begonia, Fusang, pineapple, Junzi orchid, Swiss cheese plant, Wen Zhu, Lingjian lotus, Schefflera, Rubber fig, pothos, tiger thorn, tiger tail orchid, crane hope orchid, banyan, Epiphyllum, Brassica, Chinese orchid, Belgium azalea, loose tail anemone, Schefflera, Guangdong Rohdea japonica, geranium, Hybrid Cymbidium, pocket coconut, cyclamen, Chunyu, Chlorophytum, cycas, palm bamboo, Palmflower, kumquat, aloe, peony, kidney fern, Fatsia japonica, Daidai, Dishui Guanyin, oleander, etc., the minimum requirement of room temperature is above 5 ℃, if the room temperature is too low, these flowers will appear yellow leaves.
In winter, when the sun is weak, the plants that like light or have a little shade tolerance will appear yellow leaves if they are placed in the place where there is no light or the light is too weak for a long time. For example, Aglaia odorata, poinsettia, jasmine, Fusang, geranium, camellia, cyclamen, cycas, azalea, and Clivia need to fully receive the sunlight in winter.
Many family flowers like high air humidity, such as Hybrid Cymbidium, Phalaenopsis, Boston fern, kidney fern, azalea, pothos, Wen Zhu, Swiss cheese plant, spring feather, bamboo taro, camellia, Rohdea japonica and so on. However, due to the sufficient heating and dry indoor air in most households in the north, the leaves should be sprayed with water close to the room temperature to keep the basin soil moist and avoid yellow leaves.
After winter, the temperature is low and the water evaporation is slow, so the water quantity should be reduced properly. In winter, the basin soil should be dry for plants in slow growth and semi dormancy. Because of the low temperature in winter, the water for flower watering should be stored in the appliance or dried in the sun. Do not use tap water directly to water the flower to prevent the excessive temperature difference from damaging the root system. Because the temperature is falling in winter, the metabolism of flowers is slow, or enter the dormancy state, generally potted flowers should strictly control the fertilizer and water. Shade resistant flowers, but also to avoid excessive watering caused by rotten roots and leaves. Generally, the watering time should be around noon.
In winter, most flowers enter the dormancy period, so we should try to reduce or stop fertilization. For indoor flowers that do not sleep in winter, such as Rohdea japonicas such as tiger tail orchid, fish tail anemone, palm bamboo and pothos, there is basically no requirement for fertilizer when the room temperature is about 5 ℃, so there is no need for topdressing. If the temperature is low, the root system will rot easily. The main reason is that the growth of plant roots is in a slow state in winter. The fertilizer applied can not be absorbed by the roots, but will hinder the normal absorption of roots, and will rot when it is serious. If the room temperature is high, and flowers bloom in winter, such as guayeju, cyclamen, primrose, Impatiens, flamingo, etc., it is necessary to apply a thin organic liquid fertilizer every half a month, or a small amount of compound fertilizer. In case of excessive fertilization, water in time to dilute the concentration of fertilizer solution.
