Orchids, as traditional famous flowers in China, are deeply loved by flower enthusiasts. Many enthusiasts find that after the orchid flowering period, the leaves start to turn yellow and fall off, causing great distress. What should we do with the leaves after the orchid flowering period? Let's reveal the maintenance strategy for orchid leaves after flowering.
Analysis of the reasons for the yellowing and falling off of orchid leaves
1. Improper maintenance: such as excessive watering, insufficient lighting, improper fertilization, etc.
2. Diseases and pests: such as anthracnose, leaf spot disease, aphids, etc.
3. Natural aging: orchids have a limited growth cycle, and after the flowering period, leaves naturally age and fall off.
Maintenance methods for orchid leaves after flowering
1. Control watering: Orchids prefer a humid environment but are afraid of waterlogging. After flowering, it is necessary to reduce the frequency of watering and keep the soil slightly moist.
2. Appropriate fertilization: After flowering, orchids enter a growth dormancy period. At this time, the amount of fertilizer should be reduced to avoid fertilizer damage. A low-nitrogen, high-phosphorus, and potassium compound fertilizer can be used, applied once a month.
3. Increase lighting appropriately: After flowering, orchids need sufficient sunlight for photosynthesis. Place orchids in a place with plenty of scattered light, avoiding direct sunlight.
4. Control diseases and pests: Regularly inspect orchids and deal with diseases and pests in a timely manner. Insecticides and fungicides can be used for prevention and control.
5. Prune yellow leaves: After flowering, it is necessary to prune the yellow and diseased leaves to keep the plant tidy, which is conducive to ventilation and light.
6. Provide proper ventilation: Maintaining ventilation in the orchid growing environment helps reduce the occurrence of diseases and pests.
7. Pay attention to temperature and humidity: Orchids prefer a warm and humid environment, with the most suitable growth temperature being 18-28°C and air humidity being 60%-80%. After flowering, it is necessary to control the temperature and humidity to avoid plant damage from frost or diseases.
