When the winter temperature is low, it is not suitable for the growth of most flowers. In order to make winter safe for the winter, it is necessary to move into the room one after another in the early winter, and the conservation measures taken after entering the room must be taken into account in the characteristics of various flowers.
Temperature: Adjust appropriately for different flowers
In the northern regions, the winter climate is cold and the temperature is low. Generally, southern flowers need to move into winter indoors and adjust the temperature according to the requirements of different flowers. Hi-temperature flowers, such as Milan, Poinsettia, African Impatiens, Begonias, and Cactus-like fleshy flowers, should be placed as far as possible on the interior windowsill with sufficient sunlight and high temperature (between 20°C and 25°C). The temperature must not be less than 10°C. Hi-temperature flowers, suitable for winter temperatures from 18 °C to 22 °C, the minimum temperature of not less than 6 °C. For flowers with low temperature, the winter temperature should be kept between 12°C and 15°C, and the minimum temperature should not be lower than 2°C. Aquatic flowers, such as lotuses, water lilies, Eichhornia crassipes, ponting lotus, etc., should be released immediately before the frost, and the flowerpots should be moved to the cellar or hallway hall. The temperature should be kept at 5°C. Spray water properly.
In addition, flowers that bloom in winter and spring, and flowers that are bright and warm, should be placed on the windowsill or in a sunny place near the windowsill. An evergreen flower or flower that is in a dormant state that is pleasing to the sun but can tolerate low temperatures can be placed in a cool place with scattered light. Generally, flowers that are not strictly light-required can be placed in a cool place without light. Fertilization: Minimize or stop most winter flowers from entering dormancy, so try to reduce fertilization or stop fertilization. Indoor flowers that do not sleep during the winter, such as evergreen flowers such as tiger's-earth orchid, hollyhock, palm, and green radish, have almost no requirement for fertilizer when the room temperature is around 5°C. Therefore, it is not necessary to top-dress the fertilizer. If the temperature is low, fertilizer will appear easily. Root rot phenomenon. The main reason is that the growth of the roots of plants in winter is in a slow state. The fertilized materials cannot be absorbed by the roots, but will impede the normal absorption of the roots. In severe cases, they will rot.
If the room temperature is high (above 20°C) and it is winter flowering flowers, it is necessary to apply a thin organic liquid fertilizer once every two weeks, or a small amount of compound fertilizer. It is best to use pot-free “fermented flowers†​​or fermented rice water in order to prevent the fertilizer from polluting the indoor environment.
Watering: Avoid direct watering with tap water
Due to the low temperature in winter, the watering of flowers should be stored or dried by utensils. Watering directly with tap water should not be used to prevent the temperature difference from being too large and damaging the root system. Because the winter temperatures are constantly falling, the metabolism of flowers is slow, or they enter a dormant state. Generally, pot flowers should be strictly controlled. If the pottings are not too dry, do not water them, especially shade-tolerant flowers, and avoid rot-root defoliation caused by excessive watering. General watering time should be suitable before and after noon. For some hi wet and evergreen flowers, the leaf surface should be sprayed with water that is similar to the room temperature, cleaned and dusted to facilitate photosynthesis.
Pest control: indoor should pay attention to ventilation
Due to poor indoor ventilation in the winter, some flowers often have powdery mildew, coal smoke, aphids, and red spiders. The disease can be sprayed with 0.1% carbendazim or thiophanate liquid, and pests can be sprayed with 0.2% dimethoate or insecticide. When spraying pesticides, it is best to move the pot to the outside, or you can bury the insecticidal tablets in the soil. In addition, the interior should pay attention to ventilation, the whole winter should open the window ventilation at noon in sunny weather, in order to reduce the occurrence of pests, but also conducive to the robust growth of flowers.
