How do I avoid brown flowers on the azalea in advance?
Azaleas don't have many demands. However, if you follow the following care tips, you will be rewarded with robust plants and an abundance of flowers:
- Make sure you choose the right location for your azalea species. Most people prefer shade to partial shade, without direct sunlight.
- Keep the plant moist at all times.
- Avoid waterlogging to prevent root rot.
- Ideally water with rainwater or low-lime tap water.
- Fertilize regularly.
- Remove wilted flowers regularly during the flowering period. This also promotes flower growth.
Tip
A nutrient deficiency also causes brown flowers
If the plant receives too few nutrients, it cannot carry out its vital photosynthesis and reacts with the flowers wilting and dying. To avoid this, you should regularly strengthen your azalea with fertilizer (€9.00 on Amazon) in the summer. You should also water with rainwater, as azaleas quickly suffer from chlorosis (lack of chlorophyll) if they get too much lime.
