Watering should follow the principle of "watering when dry and damp when seen". During the peak growing period, water once a day; during the dormant period, water every 2-3 days.Fertilizing techniquesLarge-leaf orchids require a lot of fertilizer, but not too much.

Too high or too low temperatures will affect their growth. In high summer temperatures, pay attention to ventilation and cooling; in low winter temperatures, appropriately increase the indoor temperature. For humidity, maintaining 60%-70% is appropriate.Pest and disease controlCommon diseases and pests of large-leaf orchids include leaf spot, anthracnose, aphids, etc. Preventive measures are as follows:1. Maintain good ventilation conditions to prevent the growth of diseases.2. Regularly check the leaves and deal with diseases and pests in a timely manner.3. Use pesticides for control, but pay attention to the method of using pesticides and the safety interval period.Pruning and repottingDuring the growth of large-leaf orchids, it is necessary to prune withered leaves and weak branches in time to maintain the beauty of the plant. Generally, repotting is done once a year, choosing spring or autumn. When repotting, pay attention to pruning the overlong roots and applying an appropriate amount of base fertilizer.To grow large-leaf orchids well, certain skills and methods need to be mastered.
