Why do the leaves of azaleas fall off?
The flowers of azaleas are bright and beautiful, and many people like to keep them at home for appreciation. So, what is the reason for the leaves of azaleas falling off? Let's find out below.
Reasons for the leaves of azaleas falling off: unsuitable environment
Azaleas are sensitive to temperature and require a relatively warm environment to grow. High or low temperatures can lead to the falling off of leaves. When caring for azaleas, they should be placed in a scattered light environment and not exposed to strong sunlight. If the temperature is relatively low in winter, they should be moved indoors in advance, and it is also necessary to avoid drastic changes in the care environment temperature.
Improper watering
The roots of azaleas are fine and have poor water absorption ability, so we need to keep the soil moist frequently. If there is insufficient water, azaleas will lose leaves due to drought. However, we should not water excessively. If the soil accumulates water, the roots of azaleas will rot, which can also lead to the falling off of leaves.
Unsuitable soil
Azaleas need to grow in acidic soil, with a pH level between 4.5 and 6 being the most suitable. However, over time, the salt content in the water can cause the soil to become gradually alkalized, which will cause azaleas to lose leaves. Therefore, when caring for azaleas, it is best to change the soil once a year to maintain the acidity of the soil better.
