What to do when the leaves of bougainvillea turn yellow or fall in autumn

1. Increase the temperature

Reason: The temperature in northern regions drops quickly in autumn. If the temperature in the breeding environment is relatively low, the leaves will turn yellow or fall off.

Treatment method: Move to a warmer place as soon as possible and ensure that the temperature does not drop below 5°C, especially in late autumn. Pay attention to keep warm when the temperature is low in the morning and evening. If conditions permit, the temperature should be raised appropriately.

2. Control moisture

Reason: In autumn, the growth rate of the plant will slow down, so the water required will also decrease. If it is watered the same amount as usual, its roots will rot, causing yellowing and falling leaves.

Treatment method: When the temperature starts to drop, you need to control the amount of watering and reduce the frequency of watering. If there is too much water in the pot, drainage should be done as soon as possible.

3. Increase Lighting

Reason: It likes sunlight. In autumn, people will put it indoors to keep warm. At this time, the sunlight will be interrupted, the photosynthesis of the leaves will be hindered, and the leaves will turn yellow.

Treatment method: Moving it indoors is the right approach, but it must be placed in a location where it can see sunlight so that the plant can receive as much light as possible.
