Why are the leaves of the bougainvillea curling, and how should it be solved?

Bougainvillea is a common household potted plant, but when people grow it, various problems often arise, and one of the most headache-inducing is bougainvillea leaf curling, which seriously reduces the ornamental value of the bougainvillea. So what are the causes of bougainvillea leaf curling? What should be done? Let's take a look together.

1. Insufficient light

Bougainvillea likes an environment with ample light. If it is kept in a place with insufficient light for a long time, its leaves will curl because of the lack of sunlight, and in severe cases, root rot and leaf drop may also occur.

Solution: If the leaf curling is caused by insufficient light, the first thing is to improve the light conditions. It is best to first place the bougainvillea outdoors, and after its leaves return to normal, place it in a spot with ample light and good ventilation for care.

2. Improper watering

In summer, when temperatures are high, if the bougainvillea is watered too little, its leaves are very likely to curl; while in winter, watering too much can also cause the leaves of the bougainvillea to curl.

Solution: For leaf curling caused by too little watering in summer, you can increase the watering frequency and amount to provide the bougainvillea with sufficient water. However, in winter, be careful not to water the bougainvillea too much. In addition, whether in winter or summer, do not let water accumulate in the bougainvillea's flower pot, otherwise the bougainvillea will grow poorly, and the root system will also rot from being soaked in accumulated water.

3. Too high temperature

High temperature is also one of the common causes of bougainvillea leaf curling. In summer, when it is hot and the temperature is high, the plant's transpiration is greater, and the leaves often suffer from insufficient water because the potting soil is too dry, and at this time leaf curling occurs.

Solution: In summer, when temperatures are high, pay attention to replenishing water in time. If the temperature is above 30 degrees, provide appropriate shade, and spray the area around the plant or the leaves to increase air humidity and lower the surrounding temperature. Generally, it will gradually return to normal after a few days.

4. Excessive fertilization

Applying too much fertilizer to the bougainvillea is also one of the causes of leaf curling, mainly because too much fertilizer leads to excessive leaf growth, and naturally the curling phenomenon appears.

Solution: If the bougainvillea leaves curl because of excessive fertilization, the remedy at this time is to rinse the soil with a large amount of clean water. After the fertilizer is diluted, the bougainvillea will slowly return to its normal leaf condition.
