How to care for azaleas
The web tells everyone about how to care for azaleas and the content of green plants and flowers in terms of azalea maintenance and management. Next, the editor will provide you with detailed answers.
Azaleas, also known as Rhododendron, are one of the top ten famous flowers in China, often used in landscaping. Many friends also like to keep a pot at home. Its leaves are lush and green, and when blooming, the flowers are numerous and colorful. A pot can be kept for many years. Growing it into an old stake bonsai is even more beautiful and eye-catching. If the leaves of the potted azalea fall off, the leaf tips turn black, or the leaves turn yellow, bloom less, or do not bloom at all, it is definitely a problem in the maintenance process, caused by these reasons, so attention should be paid to these maintenance skills:
To care for azaleas, remember these five points to prevent leaf drop and yellowing, ensuring lush growth and blooming every year.
1. Moderate sunlight
If black tips appear on new leaves during the process of caring for azaleas, and leaves easily fall off, it is likely caused by strong sunlight. As the temperature rises, azaleas should not be placed in direct sunlight, especially during the hot summer. They can be exposed to the sun in spring and autumn but should be shaded in summer to achieve a 70% shading level. Also, if the potting soil lacks water and has not been watered for many days, combined with compacted soil, it can also cause leaf drop. Therefore, it is not advisable to withhold water from it for too long.

2. Maintain ventilation and air permeability
If the location of the potted azalea has poor ventilation, soil积水, and severe lack of sunlight, it can also cause leaf blackening and leaf drop in a low-light environment. Therefore, maintaining ventilation and air permeability, ensuring at least scattered light, and keeping the potting soil not extremely dry but also not overwatered.
3. Maintain a certain level of humidity
If the air is dry and the weather is dry, besides watering in time, you can also spray some water to maintain a certain level of humidity, as overly dry conditions can also lead to dry leaves and black tips.
4. Prevent and treat diseases and pests
If the tips of azalea leaves turn black, leaf drop, or the leaves wither, it could be anthracnose. Therefore, you can spray some fungicides, such as common carbendazim or thiophanate-methyl, for prevention and treatment. To care for azaleas, the soil should be slightly acidic, maintain good ventilation, a certain level of humidity, and grow best at around 20 degrees Celsius. Under normal conditions, the light should not be too weak, and the light should not be too dim. Weak light, excessive watering, and闷养 (a term referring to overwatering and lack of air circulation) can easily cause the leaves to fall off when touched, or even result in the loss of all leaves.
