Narcissus is very fond of light. In order to ensure good growth, the light given every day should not be less than 4 hours. If the light is insufficient, the growth will be limited. Maintenance at home, can be placed on the balcony, maintain sufficient light stimulation, is more conducive to flowering. Pay attention to the high temperature period in summer, when the light is too strong, it can be reasonably blocked to avoid direct sunlight. Winter's light intensity is smaller, can contact sunshine all day, supplement sunshine at the same time, but also improve their own temperature
If it is soil culture and maintenance, it needs to be watered reasonably to maintain the growth of the bulb, judge whether there is water shortage, and then give proper amount of water support, and pay attention not to accumulate water, otherwise it will cause the bulb to rot and affect the subsequent growth.
For Narcissus in hydroponics, we need to pay attention to the problem of water change. In the first two weeks, we need to change water every day. In the later period, we can reduce the frequency of water change and change water every 2-3 days. Reasonable water exchange can prevent water quality turbidity, but also improve the fresh nutrients, in order to maintain the growth of the later period.
Growth can not be separated from the application of fertilizer, soil conservation can be fertilized regularly, hydroponic conservation can be combined with water change when dropping nutrient solution.
