When raising Narcissus, there is no accurate statement about how often to change the water. At the beginning of hydroponics, you need to change it every day, add water in the morning, and then pour it out at night, and then add it the next day. Before flowering, it is not necessary to change water so frequently. Water can be changed every 2-3 days to reduce the possibility of falling flowers. Slow growing season water change time can be extended, not so frequent, can change once every 3-5 days, but pay attention not to change water for a long time, otherwise it will affect the water quality, make the water inside rotten, thus affecting the growth.
1. Light: during daily maintenance, we should pay attention to replenishing sunlight, which can synthesize nutrients in the growth, and can't be put in the dark environment for a long time, so the growth will be affected, and the growth will become weak..
2. Container: the height of the container does not need to be too high. You can choose a shallow basin with no drainage holes under it.
3. Temperature: in order to ensure normal growth, the temperature range should be appropriate. It is better to keep the temperature in 12-15 ℃, not too high.
4. Pruning: pay attention to the problem of pruning, remove the withered and yellow leaves in time, and also cut short the long leaves.
