Reasons Why Azalea Flower Buds Wither and How to Fix Them
1. Water Promptly
Cause: The azalea's color and shape still look fairly normal, but it is just wilting. This may be because the potting soil is too dry and it has not been watered for a long time.
Solution: Water it promptly, and it will recover quickly after watering. This situation does little harm to the flower buds, and the flowers can continue to bloom.

2. Mist to Increase Humidity
Cause: The flower buds change color and wilt noticeably, and they do not recover after watering. This may be because the azalea is in an environment that is too dry.
Solution: Increase the air humidity around the azalea by misting some water around it.
3. Treat the Specific Cause
Cause: If it is during the flowering period, watering too frequently or applying heavy fertilizer can damage the roots and also cause the flower buds to wither.
Solution: If this is the case, watering or some simple maintenance will not help it recover. We need to analyze which aspect of the environment we previously gave it fails to meet its flowering needs and treat the specific cause, so that it can recover quickly.
