The anthurium is one of the evergreens on the windowsill. With a little sensitivity, the plant develops splendidly and is a beautiful room decoration with its intensely colored bracts and flower spadix. Unfortunately, she also reacts quite sensitively to care errors. It often gets brown spots on the leaves.
What causes brown spots on the leaves of an anthurium?
If an anthurium has brown spots, there may be causes such as incorrect watering behavior, pests such as spider mites or fungal diseases such as leaf spot. To remedy the situation, you should adjust the watering behavior, increase the humidity and take appropriate measures in the event of pest or fungal infestation.
The reason for this could be:
- Watered too much or too little
- Pests such as spider mites
- Fungal diseases such as leaf spot
How should you water?
The natural home of the flamingo flower is tropical rainforests, where it thrives as an epiphyte or in the light shade of the jungle giants. Therefore, you need an evenly moist, but not soggy, substrate and sufficient air humidity. These conditions are not correct, the plant often reacts with brown spots on the leaves.
You can remedy this as follows:
- Water regularly, always when the top centimeters of the substrate feel dry.
- Increase humidity. This can be done using an indoor fountain or evaporator dishes.
Fighting pests
The tiny spider mites suck the plant sap from the leaves, so that they initially develop brown spots and then wilt. The animals living on the underside of the leaves are often difficult to see with the naked eye. If you mist the flamingo flower, the webs will become visible.
Spider mites are quite stubborn and often defy home remedies. To prevent them from spreading further, the anthurium should initially be placed individually. Then treat the plant with a suitable product (€9.00 on Amazon).
The leaf spot disease
The leaf spots on this one are quite characteristic: The brown spots usually have a yellow halo, which stands out clearly from the green with a black edge. Cut back the affected leaves and also use a spray that kills the fungus.
Tip
Anthuriums are quite sensitive to insecticides and fungicides. Therefore, first test the active ingredient on a single leaf and wait a few days. If the foliage shows no damage, you can treat the entire plant.
