What Causes the Yellowing of Bougainvillea Leaves

The yellowing of bougainvillea leaves is mainly caused by improper care methods.

What's Wrong with the Yellowing of Bougainvillea Leaves

The yellowing of bougainvillea leaves is mainly caused by improper care methods. The reasons include incorrect fertilization, improper watering, insufficient light, and the occurrence of diseases and pests. Measures should be taken according to the actual situation for remedy.

1. Incorrect Fertilization

Bougainvillea is in a dormant state during high temperatures or severe cold. Incorrect fertilization can cause fertilizer damage, leading to root rot and subsequent leaf yellowing. If fresh fertilizer is applied, it can directly damage the roots, causing leaf drop and even plant death.

2. Improper Watering

Bougainvillea's water requirements vary with each season. Failing to adjust the amount of water appropriately can lead to yellowing of the leaves. Although it does not have strong drought resistance, excessive watering can easily cause waterlogging in the pot, preventing root respiration and causing the leaves to turn yellow.

3. Insufficient Light

Bougainvillea is a light-loving plant, so light is crucial for its growth. Without sunlight or insufficient light to meet growth requirements, the branches will become weak, and the leaves will turn yellow.

4. Diseases and Pests

Bougainvillea may develop various diseases during growth, including leaf spot and brown spot diseases, which can harm the plant's growth, causing yellow leaves. In severe cases, it may lead to the death of the bougainvillea.

What to Do about Yellowing Bougainvillea Leaves

1. Fertilization: If bougainvillea is fertilized too much, stop fertilizing for a period and then avoid using fresh or concentrated fertilizers. Control the amount of fertilizer applied at one time.

2. Watering: Generally, water once a day during spring and autumn, and twice a day during summer (morning and evening). In winter, when temperatures are lower, keep the potting soil moist but avoid waterlogging.

3. Sunlight: Bougainvillea is a light-loving plant, so it must be placed in a well-lit and well-ventilated area to ensure normal growth and increase flowering frequency. Provide shade during the summer.

4. Diseases and Pests: If leaf spot disease occurs, apply kining cream ointment to the affected area and cut off the diseased branches. For brown spot disease, prune the diseased leaves and then spray with退菌特 (tuijunte) or other fungicides.
