Prevent the yellow leaves of flowers after entering the room

1. Controlled watering: after entering the house, the water transpiration of flowerpots and plant surfaces 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 basin soil, and the leaves on the upper part of the plant will turn yellow.

two。 Reduce fertilization: in autumn, most flowers change from vigorous growth to slow growth. After flowers enter the house, they will enter the stage of rapid growth due to the rise in temperature. However, the absorption of fertilizer is not as good as that in summer, so it is necessary to reduce or stop topdressing to prevent the plant from yellow leaves.

3. Adjust the light: some flowers that like strong light, such as rose and Fusang, will appear yellow leaves due to lack of light if they are placed in a shady place after entering the room. On the contrary, placing the bird's nest fern and tortoise bamboo in the place where the light is too strong will also cause the leaves to lose green and yellowing. The location of flowers in the room should also be adjusted reasonably.

4. Environmental ventilation: the environment is closed, which 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.
