The Anthurium plant, also known as tailflower, flamingo flower, and laceleaf, is a tropical plant often grown as a houseplant or in gardens
They are known for their beautiful flowers, which come in various colors.
However, anthuriums can be susceptible to root rot, which can kill the plant.
This article will provide a complete guide on how to save an anthurium from root rot.
What Is Root Rot?
Root rot is a disease that affects the roots of plants.
It is caused by fungi or bacteria that invade the roots and cause them to decay.
The roots may become discolored, mushy, and smelly.
This can lead to the plant’s inability to absorb water and nutrients, which can kill the plant.
What Causes Root Rot?
Knowing what causes root rot is essential to avoid it in the future.
There are a few different things that can cause root rot:
Overwatering
Overwatering is the most common cause of root rot.
When the roots of a plant are constantly wet, they become vulnerable to fungal and bacterial infections.
They also have difficulty absorbing oxygen, leading to the roots’ decay.
If you think your indoor plant is overwatered, check the soil.
If it’s soggy or feels wet, it’s probably overwatered.
The best way to water an anthurium plant is to allow the top of the soil to dry out before watering again.
Poor Drainage
Poor drainage is another common cause of root rot.
When the anthurium roots are constantly sitting in water, they can become waterlogged and begin to decay.
It’s essential to ensure your anthurium is planted in a well-draining potting mix and that the pot has drainage holes.
If you’re unsure whether your pot has drainage holes, you can always drill some yourself.
Make sure the holes are big enough for water to drain easily.
Compacted Soil
Compacted soil can also lead to root rot.
When the roots are constantly pressed against compacted soil, they can’t get the oxygen needed to survive.
This can lead to the roots decaying.
If you think your anthurium’s soil is compacted, you can loosen it up by mixing in some perlite or sand.
Fungal Infections
There are many different fungi and bacteria that can cause root rot.
The most common include:
- Phytophthora species
- Pythium species
- Rhizoctonia species
- Fusarium species
These organisms are often found in soil, water, or plant debris.
They can invade the roots of plants through wounds or natural openings.
Once established, they can spread rapidly, causing the roots to rot.
Root Damage
Root damage can also lead to root rot.
This can be caused by physical damage, such as from gardening tools, chemical damage from herbicides, or biological damage from nematodes.
The roots may become infected with fungi or bacteria through the wounds.
This can lead to the roots rotting.
What Does Anthurium Root Rot Look Like?
There are a few different things you can look for to determine if your anthurium has root rot.
The most common signs include:
Wilting Leaves
The first sign of root rot is usually wilting leaves.
The leaves may droop or turn yellow.
This is because the plant is not getting the water it needs from the roots, as they are rotting.
Yellowing Leaves
Yellowing leaves is another common sign of root rot.
The leaves may turn yellow or brown and fall off the plant.
The plant’s rotting roots can’t absorb nutrients, so the leaves turn yellow and eventually die.
Dry and Shriveled Leaves
Dry and shriveled leaves are also a sign of root rot.
This is because the plant isn’t getting the water it needs, so the leaves dry out and eventually die.
Although, it’s important to note that dry and shriveled leaves can also be a sign of underwatering, so check the soil before assuming your plant has root rot.
Brown or Black Spots on Leaves
Black or brown spots on the leaves are another sign of root rot.
These spots are usually a sign of a fungal infection.
The spots may be small and brown or large and black.
They may also be raised or sunken.
Soggy Soil
Soggy soil is another sign of root rot.
If the soil is constantly wet or soggy, it’s a sign that the roots are rotting.
When the roots rot, they can’t absorb water, so the soil stays wet.
This can also lead to the plant’s leaves wilting or turning yellow.
Bad Smell
A foul smell is another common sign of root rot.
The roots may start to decompose, which can cause a foul odor.
If you notice a bad smell coming from your plant, it’s a sign that the roots are rotting.
Mushy and Blackened Roots
Mushy and blackened roots are the most obvious sign of root rot.
If you notice that the roots are soft, mushy, or black, it’s a sign that they are rotting.
Healthy roots are firm, white, or tan.
If you think your anthurium has root rot, the best thing to do is to take it out of the pot and check the roots.
If they are soft, mushy, or black, it’s a sign that the plant has root rot.
Stunted Growth
Stunted growth is another common sign of root rot.
If the plant’s roots are rotting, it won’t be able to get the nutrients it needs to grow.
This can cause the plant to stop growing or to grow slowly.
One of the first signs of stunted growth is usually smaller leaves.
If the plant’s leaves are smaller than usual, it’s a sign that it isn’t getting the nutrients it needs to grow.
How To Treat Anthurium Root Rot
Anthurium root rot is a severe problem, but it can be treated.
It’s crucial to catch the root rot early, as it can spread quickly and kill the plant.
Here is a step-by-step guide on how to treat anthurium root rot:
1. Remove the Plant From the Pot
The first step is to remove the plant from the pot.
Carefully take the plant out of the pot and check the roots.
If they are soft, mushy, or black, it’s a sign that the plant has root rot.
2. Clean the Roots
Once you’ve removed the plant from the pot, it’s time to clean the roots.
Remove as much old soil as possible, being careful not to damage the roots.
Then, rinse the roots with clean water.
3. Remove the Rotting Roots
The next step is to remove the rotting roots.
Carefully cut away any soft, mushy, or blackened roots.
Cutting away the rotting roots will help to stop the spread of root rot.
It’s essential to be careful not to damage the healthy roots.
4. Discard the Soil
After you’ve removed the plant from the pot and cleaned the roots, it’s time to discard the soil.
The old soil may be contaminated with fungi or other pathogens that can cause root rot.
It’s best to start with fresh soil when you replant the anthurium.
5. Wash the Pot
