1. After controlling the watering into the room, because the space is not as wide as outdoors, the water transpiration of the flowerpots and plant surfaces is reduced. 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. Adjust the flowers to light some of the hi-bright flowers, such as rose, hibiscus, etc., should be placed in a shaded area 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. Environmentally-ventilated and closed environment will lead to the gradual increase of the content of ethylene in the air that causes the aging of flowers. 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. Maintain proper temperature Because of the unfavorable ambient temperature, many flowers will be yellow leaves, especially if the temperature difference between the front and rear of the flower is large. 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.
