How to prevent yellowing of flowers after they enter the house

Control watering

After the flower pots are brought into the room, the amount of water transpiration on the surface of the flower pots and plants is reduced because the space is not as open as outdoors. If you continue to water the plant as you did before, the wet soil in the pot will cause root rot and the leaves will turn yellow.

Reduce fertilization

After the flowers are brought into the house, the rising temperature will cause them to enter a stage of rapid growth. However, they do not absorb as much fertilizer as in summer, so you should reduce or stop topdressing to prevent the plants from turning yellow leaves.

Adjust lighting

Some flowers that like strong light, such as roses and hibiscus, will have yellow leaves if they are placed in a shady place after entering the house. On the contrary, placing bird's nest ferns and monstera, which prefer shade, in places with strong light will cause their leaves to lose their green color and turn yellow. The placement of flowers in the room should also be adjusted reasonably.

Environmental ventilation

The environment is closed and the ethylene content in the air gradually increases. At this time, many flowers that are sensitive to ethylene will turn yellow leaves due to aging. Therefore, maintaining good ventilation is one of the effective measures to prevent yellow leaves of indoor flowers.

Keep the temperature

Many flowers will also have yellow leaves, especially when there is a large temperature difference before and after the flowers are brought into the room. If the outdoor minimum temperature is 5℃ and Milan and azalea are moved to the greenhouse, due to lack of cooling, the plants will soon have yellow leaves when the daytime ambient temperature rises to 25℃. This situation also needs to be prevented.
