1. Watering method: the air humidity should be kept between 70% and 80% in pot culture. In spring, the temperature gradually rises, and the water evaporation begins to become faster. Spray water to the phoenix eye blue frequently to increase the air humidity. Usually, the flower soil should be kept slightly wet. If the soil is dry, it should be watered with water.
2. Water quantity: when watering, make the water level of the container slightly higher than that of the basin soil. When the water level is lower than half of the height of the soil, water needs to be added appropriately. In the growing period, it needs a lot of water, so it needs more water. Before flowering, watering should be reduced to promote flower bud differentiation.
3. Watering frequency: it can be watered twice a week at ordinary times. When the wind is strong and the air is dry, the moisture of the soil evaporates faster. At this time, it is necessary to observe whether it is short of water every day and water it in time. In summer, water it every day to avoid water shortage. The water evaporated from the flowerpot must be replenished in time, otherwise the plant will suffer from drought due to the loss of water in the flowerpot.
The growth of Eichhornia crassipes requires higher salt and pH value in water. When the salt content of water exceeds 0.06%, it will die. PH 7 is the most suitable environment for its growth. Water from ponds and rivers can be used for water culture of Eichhornia crassipes. Put some mud on the bottom of the container. In addition, you don't have to change water too often.
