If the narcissus is cultured in water, you should pour clear water into the basin in the early morning every day, and then place it in a place with sufficient light in the daytime. At night, you should pour out the water in the basin without moving the bulbs, and move it into the room. At the beginning of cultivation, you need to change the water every day. After a period of time, you can change the water every three days or so. Pay special attention to the proper water temperature. Do not overheat or cool.
If the narcissus is cultivated by soil culture, it can be watered once every other day or two days. Each time, it must be watered thoroughly, so that the root system of Narcissus can get enough water. If it can't be watered only half through, it can keep the moisture of the soil at all times. Especially in spring, it is in a period of relatively vigorous growth. It's better to water once every other day, and it can't be cut off, which will affect its growth.
