What to do if the leaves of an azalea are brown?
Brown leaves on an azalea can be caused by lack of water, leaf spot, or iron deficiency (chlorosis). To save the plant, you should water it sufficiently, remove any affected parts and, if there is iron deficiency, reduce the lime content.
What does it mean when the azalea turns brown leaves?
If the leaves of the azalea turn brown, this problem can have several causes:
- The plant receives too little water and dries up.
- The leaf spot disease is behind it. It is caused by various fungi, viruses or bacteria.
- If the edges of the azalea leaves turn brown or yellow, this may be due to iron deficiency (chlorosis).
Examine your plant in detail to find out the cause and take correct action.
What can I do if my azalea is dry?
If the leaves of the azalea are brown and dry, you should check the plant soil. To do this, stick your finger about two to three centimeters deep into the soil. If the soil is dry here, the plant suffers from a lack of water. To save the azalea, you shouldwater it as quickly as possible, but avoid waterlogging. Treat azaleas in pots or buckets toRainwater immersion bath If no more air bubbles appear after about ten minutes, the root ball has become saturated.
How can I save my azalea from chlorosis?
If yellow to brown edges appear on the leaves, the azalea is suffering from iron deficiency. This is causedby too high a lime contentin the irrigation water and in the plant soil. You canupgrade thesoilTo do this, mix the existing soilwith sand and compostThis will equalize the pH -Value of the soil to the needs of the azalea. It prefers an acidic soil for optimal nutrient absorption.
Ideally prevent iron deficiency by watering with low-lime water, preferablyRainwater.
Azalea has brown spots - Is this leaf spot?
Leaf spot is characterized byround or elongated, yellow, brown to black spots. It iscaused by various fungi, viruses and bacteria If you notice an infestation, you must act quickly. Cut off all affected parts of the plant with clean secateurs (€14.00 on Amazon) and dispose of them with household waste. Do not compost them under any circumstances, otherwise the pathogens will spread to other plants. Strengthen the plant with a homemade plant decoction made from nettles to provide the azalea with sufficient nutrients.
Tip
Take good care of your azalea and you will be rewarded with a robust and disease-resistant plant
To prevent damage to your azalea, you should always take good care of it. Azaleas come from moist mountain forests. That's why they always like it moist (but definitely avoid waterlogging), relatively cool (modern varieties survive European summers well) and shady without direct sunlight. However, since there are numerous varieties of azalea, each type has its own characteristics, which you can find out from your specialist dealer.
