Orchids are mainly watered with dilute water. Remember not to water too much. In summer and dry season, the water mist can be appropriately increased, and it is best to spray 1 ~ 2 times a day. Use less water in autumn and winter. During the growing period, dilute phosphorus and potassium fertilizer solution should be applied once every two weeks, and water should be poured in time.

Precautions:
Pay attention to ventilation when cultivating bluegrass, so as to avoid air quality degradation caused by poor ventilation. The respiratory function of bluegrass is inhibited, which leads to the yellowing of leaves and reduces the ornamental value.
If the permeability is too poor, it will easily lead to various pests and diseases. So be sure to pay attention to the ventilation of bluegrass. Finally, pay attention to the PH value of water quality when watering, and don't water with alkali. After the water is exposed to the sun, the pH value should be adjusted, and then the acidity in the soil should be supplemented regularly.
