1. Maintain temperature: Narcissus likes cool climate, although it has certain cold resistance, it can not withstand long-term low temperature.The temperature in winter in the northern region is relatively low, so it must be moved indoors in time, especially for hydroponic daffodils, and the temperature should be kept above 5-10 degrees Celsius.Narcissus in southern areas can not be moved indoors, but also covered with a layer of film, can play a role in keeping out the cold.Generally, it blossoms in January and February, and the temperature will be kept above 10 degrees Celsius after budding, so as to ensure flowering.
2, the right amount of light: light in the growth is also essential, can be placed in a bright place, every day to give about 6 hours of sunlight, can not see insufficient light.
3. Appropriate fertilization: In winter, daffodils are still in the growth stage, so fertilization can not be missing, you can properly fertilize, a little phosphorus fertilizer before flowering.
4. Ensure water temperature: When the daffodils change water in winter, the water must be kept at a good temperature. After the water is taken out, place it for a while, and then change it when the water temperature is about the same as the room temperature.
Narcissus has a certain degree of cold resistance, as long as the correct maintenance methods are adopted, it will not be frozen to death in winter.If hydroponic daffodils are placed in a sub-zero environment for a long time, they may be frostbitten and frozen to death.
