Storage methods of flower seeds to improve meteorological conditions and prevent yellow leaves after entering the house

In the north of China, the phenomenon of yellow leaves often appears after the cold-resistant flowers enter the house. There are many reasons for this situation, but in terms of improving meteorological conditions, if it is not normal leaf senescence, attention should be paid to the following aspects to prevent it.

1. Control watering

After entering the house, the water transpiration of flowerpot and plant surface decreased because the space was not as open as outdoor space. If it is still watered as before, the rotten roots will be caused by the wet pot soil, and the reaction of the upper part of the flower plant is that the leaves turn yellow.

2. Adjust the lighting

Some flowers that like bright light, such as Fusang and rose, will appear yellow leaves if they are placed in a shady place after entering the house. On the contrary, placing tortoise-backed bamboo and bird's nest ferns in places where the light is too strong will also cause the leaves to lose green and yellowing. Therefore, it is necessary to reasonably adjust the placement of flowers and plants.

3. Proper ventilation

The closed environment will gradually increase the content of ethylene in the air, which leads to flower senescence. At this time, many flowers that are sensitive to ethylene are particularly prone to yellow leaves. Therefore, keeping good ventilation is one of the effective measures to prevent the yellow leaves of indoor flowers.

4. Keep it warm.

Due to the discomfort of ambient temperature, many flowers also have yellow leaves, especially when the temperature difference is large before and after entering the house. For example, if the minimum outdoor temperature is about 5 ℃ before the cuckoo or Milan is moved to the greenhouse, and because the temperature is not cooled down, and the ambient temperature rises to about 35 ℃ during the day, the plant will soon have yellow leaves, so growers must prevent similar situations.
