1. Controlling watering: After entering the room, the water transpiration of the flowerpots and plant surfaces has decreased due to the fact that space is not as wide as outdoors. If it is still watering as it was, it will cause rot because of the dampness of the potted soil. At this time, the leaves of the plant's ground will yellow.
2. Reducing fertilization: Most flowers in autumn have grown from strong growth to slow growth. After the flowers enter the house, they will enter a stage of rapid growth as the temperature rises. However, the absorption of fertilizers is not as good as summer, so it is necessary to reduce or stop top dressing to prevent yellow leaves.
3. Adjusting the light: Some flowers that are bright and light, such as rose, hibiscus, etc., should be placed in shade after entering the house. Due to lack of light, yellow leaves will appear in the plants. On the contrary, placing the nested fern and the Monstera in a shade of light will also result in chlorosis and yellowing of the leaves. The placement of flowers in the room should also be adjusted reasonably.
4. Environmental ventilation: The environment is closed and the content of ethylene in the air, which causes the senescence of flowers, will gradually increase. At this time, many flowers that are sensitive to ethylene are particularly susceptible to yellow leaves. Therefore, maintaining good ventilation is one of the effective measures to prevent the yellow leaves of flowers in the room.
5. to maintain appropriate temperature: Due to the unfavorable ambient temperature, many flowers will be yellow leaves, especially in the case of a large temperature difference before and after the entrance of the flowers. For example, if milan and cuckoo are moved to the greenhouse when the minimum outdoor temperature is around 5°C, due to the lack of attention to cooling, the temperature will rise to around 25°C during the day and the plants will soon appear yellow leaves. This situation must also be prevented.
