Why is your Anthurium bud turning brown?
The anthurium plant produces small flower buds, and the bud can turn brown for a number of reasons, including:
1) vermin
Pests can feed on the leaves, flowers and buds of the plant. excursions and aphids are the most common pests that infect an anthurium plant.
2) fungal disease
If pests are not the cause, the problem could be caused by various fungi such as Fusarium, Pythium, and Phytophthora.
These fungi cause brown spots and blemishes on buds and leaves. Dark spots spread unevenly and quickly.
3) Low humidity
Low humidity leads to many changes in the shoots and leaves of Anthurium.
Many species lose their buds and leaves, and the tips and edges of the leaves darken.
4) underwater
Insufficient watering also causes brown buds and leaves. It is more likely to affect older leaves and can cause them to turn completely brown and drop.
It also affects the flower buds and causes them to wilt and not bloom.

If your plant is placed in a cold room during the winter, or within reach of a cold air conditioning duct, this problem can occur.
How to prevent your Anthurium bud from turning brown?
To prevent your Anthurium flower bud from turning brown, try the following:

Houseplant pests should be detected as early as possible because they not only harm your plant, but also pose a risk to neighboring plants.
Check both sides of leaves, flowers and buds. Also inspect the soil and stems for mealybugs and thrips.
Once you find the pest infestation, remove the affected plant to prevent the insects from spreading to others.
Remove as many parasites as possible by hand or wash infected areas with water.
Pest prevention:
Use neem oil or horticultural oil on the leaves to kill pests and prevent regrowth.

2) Remove diseased plants
If the anthurium is affected by a fungus, remove the affected parts as soon as possible. Using a fungicide can help.
However, fungal diseases are difficult to treat and the best solution would be to discard the plant to save other plants.

3) Improve humidity:
If low humidity is the problem, try grouping your plants together to improve the humidity.
Using a shallow tray or saucer filled with water under the pot can benefit the plant.
Placing the plant in a kitchen or bathroom with high humidity will also improve plant growth and repair browning buds.
Prevention:
Always make sure your anthurium has adequate humidity. Use an electric humidifier if you want to monitor your plant closely.
4) Improve irrigation
Water your anthurium plant when the top 1 to 2 inches of soil looks dry. Soak the soil well and allow the pot to drain excess water for several minutes.
Prevention:
Always keep a good watering schedule for your Anthurium.
Take plenty of breaks between waterings, but don’t let the plant wilt. Otherwise, it will stunt the growth and delay the flowering of the buds.

Why does your anthurium have brown spots on the flowers?
The flowers are the main reason this plant is grown indoors. However, brown spots can spoil the beauty of faded flowers or leaves.
Brown spots on Anthurium flowers can be caused by the following:
1) Overfertilization
Excess fertilizer is toxic to leaves and roots. Too much nitrogen fertilizer can cause brown spots on flowers.
How to fix it:
Wash the soil with plenty of water, this will remove excess fertilizer. Then pour the water from the pot to avoid waterlogging.
Repot the plant in a different potting mix if there is a lot of fertilizer buildup in the soil.
Prevention:
Take breaks of almost 5 months between fertilizing your plant.
2) Acclimatization
Suddenly moving the plant from one area to another can cause brown spotting or browning.
The plant would be well acclimated to a particular condition of light, humidity and temperature.
If you move it from this place, you will get stains. Spots are less of a critical problem than whole flower browning.
How to fix it:
If you need to move the plant to a different location, such as from indoors to outdoors, move it gradually to the location so that it does not experience fluctuation shock.
Make sure the humidity, temperature, and sunlight are good in the new location.
Prevention:
To avoid this, be sure to choose a suitable place to put your plant when you buy it and don’t move it frequently.
3) Bacterial infection
Bacterial blight causes leaf spots and flower spots. First, the infection appears as yellow spots. As the disease progresses, the spots turn brown.
How to fix it:
Remove or burn all infected parts of the plant.
Prevention:
Keep the leaves dry, as bacteria will grow on damp surfaces. Improves air circulation around leaves to prevent bacteria growth.
Use clean tools to trim or prune your plant.
Why are your Anthurium flowers turning brown?
There can be several reasons why Anthurium flowers turn brown:
1) Natural aging
Flower browning may be part of the natural aging process. Older flowers and leaves often turn brown and begin to wilt.
2) Sunscreen
Sunlight is beneficial for flower growth. Helps produce more flowers.
However, excessive direct sunlight can cause the flowers to dry out and turn brown.
If your plant has trouble finding light, try East to help control lighting.
3) Nutrient deficiency
Nutrient deficiency is also one of the main causes of flower browning.
Soils deficient in nitrogen, phosphorus and potassium also cause the plant to turn brown.
4) Overwatering
Anthurium requires good watering to grow. Too much water can cause root rot and can also cause fungal problems.
All of this ends up turning the leaves brown.
