What to Do When Bougainvillea Leaves Curl? Causes and Solutions

Bougainvillea is a common household potted plant, but various problems often arise during cultivation, and one of the most troublesome is curled bougainvillea leaves, which severely reduces its ornamental value. So what causes bougainvillea leaves to curl? And what should be done? Let's take a look together.

1. Insufficient Light

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

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

2. Improper Watering

In the high temperatures of summer, 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: If the leaf curling is caused by too little watering in summer, you can increase the watering frequency and amount to ensure an adequate water supply for the bougainvillea, but 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 roots will rot from being soaked in standing water.

3. Excessive Temperature

High temperature is also one of the common causes of curled bougainvillea leaves. In the hot summer, the plant's transpiration is greater, and the potting soil often becomes too dry, causing insufficient water in the leaves, which leads to leaf curling.

Solution: In the high temperatures of summer, pay attention to replenishing water in time. If the temperature is above 30 degrees, provide appropriate shade and spray water around the plant or on the leaves to increase air humidity and lower the ambient 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, which naturally results in curling.

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