Why do the tips of azalea leaves turn black and burn?
When we take care of azaleas, we may encounter the situation where the leaf tips turn black and burn. What causes this? Let's explore this together below.
Reasons for the blackening and burning of azalea leaf tips: excessive spraying of water
Azaleas prefer to grow in a humid environment, so it is necessary to frequently spray water on them to maintain humidity during daily maintenance. However, if we spray water too frequently, the azalea leaves may turn black and burn at the tips. This is because the leaves of azaleas have villi, and water droplets gathering on the villi can affect the leaves' respiration, resulting in blackened and burned leaf tips. After spraying water on azaleas, we should maintain good ventilation.
Overwatering
Azaleas not only need to grow in a humid environment but also require moist soil. This means we need to water them frequently. However, if the water exceeds the absorption limit of the azaleas, it can lead to waterlogging, causing the roots to rot. Without nutrients being transported from the roots, the leaves will also turn black and burn.
Poor soil aeration
The roots of azaleas are relatively delicate, so the soil needs to maintain good aeration. If the soil aeration is poor, the roots of the azaleas will not be able to breathe normally, leading to root rot, similar to waterlogging. The leaves will also show blackening and burning. Therefore, it is important to regularly loosen the soil for azaleas and change the soil.
