How to grow azaleas well
The editor introduces how to grow azaleas well and the key points of azalea care, as well as knowledge about flowers. Let's take a look together.
Azaleas, also known as rhododendron, are one of China's top ten famous flowers, often used in landscaping. Many friends also like to keep a pot at home. Its leaves are lush and green, and when in bloom, the flowers are abundant and colorful. A pot can be kept for many years. Growing it into an old stake bonsai is even more beautiful and flowers are stunning. If the potted azalea drops leaves, 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 process of care. There are these reasons causing it, so attention should be paid to these points of care techniques:
Remember these 5 points when growing azaleas: no leaf drop, no yellow leaves, lush branches and leaves, and blooming every year
1. Moderate lighting
If black tips appear on the new leaves during the process of growing 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 during the middle of the day, especially during the high summer temperatures. Both spring and autumn can be exposed to the sun, but summer requires shading to achieve 70% light blocking. Also, if the potting soil is short of water and has not been watered for many days, combined with compacted soil, it can also cause leaf drop. Therefore, it cannot be left without watering for a long time.

2. Maintain ventilation and air permeability
If the location where the potted azalea is placed has poor ventilation, waterlogging in the potting soil, and severe lack of light, it can also cause leaf blackening and leaf drop in a weak light environment. Therefore, maintaining ventilation and air permeability is necessary, with at least scattered light. The potting soil should not be extremely dry but also not overwatered.
3. Maintain a certain level of air humidity
If the air is dry and the weather is dry, in addition to watering in time, you can also spray some water to maintain a certain level of air humidity, as excessively dry conditions can also lead to dry leaves and black tips.
4. Control pests and diseases
If the tips of azalea leaves turn black, leaf drop, and the leaves become dry, it may be caused by anthracnose. Therefore, fungicides such as ordinary carbendazim or methyl thiophanate can be sprayed for control. When growing azaleas, the soil should be slightly acidic, maintain good ventilation, a certain level of air humidity, and grow well at around 20 degrees Celsius. Usually, the light should not be too weak or too dark. Weak light, excessive watering, and stuffy conditions can easily cause the leaves to fall off when touched, or even result in the leaves dropping completely.
