Root Rot in Anthurium

The velvety appearance of the anthurium and heart-shaped leaves will make you feel awestruck.

In the beginning, you’ll have to create the perfect conditions for these beautiful tropical plants to flourish. Root decay is the main cause of death from anthurium.

This article will give information on how to recognize, treat, and prevent anthurium root rot to prevent it from happening again.

Anthurium root rot is recognized by the soft leaves that change color from brown to yellow and wilted, mushy stems, and a smelly soil. If you notice these symptoms, remove your anthurium from its pot, trim off the parts that are rotten and treat the healthy roots. After that, transfer your plant into a new pot that has drainage-friendly soil, and avoid overwatering.

Signs of Anthurium Root Rot

Yellowing Foliage

Anthurium root rot can be easy to overlook until it’s late. The rot disease is most destructive beneath the ground, which means that the visible signs may take time to show up.

Although it’s known as “root rot,” I know the presence of it in my anthurium by taking a look at its leaves. The appearance of yellowing leaves on anthurium is among the first symptoms of root decay.

If the leaves begin to change color it is likely that the damage is already happening beneath the soil. It’s easy to discern by the name, root rot is a problem that affects the roots which are the main source of nutrients as well as water absorption.

The leaves change color due to the accumulation of water and a deficiency in vital nutrients such as nitrogen cause chlorophyll to degrade.

Alongside changing from black or brown Long-term damage to leaves can result in the leafs to fall and fall from the tree.

The leaves that are yellow don’t always signify anthurium root decay. Exposure to direct sunlight may cause them to turn yellow, which is often followed by bleached or brown leaves tips.

Remove the plant from the window. The leaves that are yellow can be caused by the bacterial will. It could alter the color of stems as well as leaves, ranging from bronze to yellow.

Brown Leaves and Leaf Tips

When the leaves turn yellow, you might notice uneven marks, brown spots, or patches of the leaves.

The majority of the time, they appear clear on the leaves’ undersides and those close to ground.

The excessive moisture in leaves causes leaf edema that damages the edges of the leaves. In the end, the browning of leaves usually starts around the edges and tips of the leaves.

As the root rot progresses the entire leaf will turn wet, mushy and even brown.

This is due to the rot-related disease in the underground affects the roots and causes these conditions occur.

Don’t believe that your anthurium is suffering from root rot because the leaves’ tips are dark brown.

They are, instead, the first signs of a variety of issues that could affect anthuriums.

Poor water quality, overwatering, pest infestations, fertilizer burn as well as sun-scorch can be all possible reasons.

Stunted Growth

Root rot could be the reason why your anthurium seems to be affected. Perhaps the leaves that are sprouting up are smaller, appear sickly, or are oddly shaped like wrinkles.

Root rot is a common problem to stop the flow of nutrients and other resources needed to support new growth.

Discolored, Soft, Mushy, and Curled Stem

A soft, wilted stem is typically the first indication that your anthurium is suffering from root decay. The stems may be extremely soft, discolored, and even distorted.

Since they’re rotting or overflowing with moisture, they may be wrinkled, twisted, or swelling.

Dark Mushy Roots and Smelly Soil

You can determine whether your anthurium is suffering from root rot by looking at the soil of your plant and its roots.

The first step is to check the plant’s root system with a gentle taking it out of its container.

Root rot is most likely to manifest when the roots are brown, black or darkened. They may also be soft, mushy, or soft and spongy.

It’s common for damaged roots to become slippery and flake off and expose the decayed tissues within the roots. Don’t be shocked if you get a strong smell.

Causes of Anthurium Root Rot

Anthurium root rot. The first is fungi that are borne by soil and soil that is wet cause the condition.

The causes of the waterlogging of soil and root rot are:

[1] Prolonged Overwatering

The most frequent cause of water loss is overwatering. reason for anthurium root rot. As a gardener, know the importance of taking care to water. The more often I water the more effective.

However, this isn’t the case for anthuriums. A high amount of watering could result in prolonged periods of moist or wet soil surrounding your plant’s roots.

This is the ideal environment for root rot that is caused by waterlogging.

If the soil is too moist, air pockets within the growing medium expand, and roots decay and die due to the lack of oxygen.

If you are watering your anthurium, ensure that you be aware of the time in your your mind. Additionally, allow the top 2 or three inches dry out between irrigations.

[2] Poor Drainage

The overflowing of water could be the cause the root-rot of Anthurium. If the pot is not equipped with drainage holes, the problem are likely to get worse. The problem with drainage could be the result of:

  • Potting your anthurium in the wrong pot – In the event that your pot becomes too big the soil will turn waterlogged or sloppy. If the pot isn’t big enough it could result in excessively watering the plant. The container is either too small or too big for your thurium could negatively impact drainage.
  • Drainage holes blocked by obstructions – The lack of drainage holes is not the only thing that affects drainage. The compacted soil, rocks or other materials could also block the drainage holes. This can prevent liquid from draining.
  • The wrong potting mix The potter’s mix is perfect for Anthuriums. The moisture can accumulate within the mix when it’s too heavy and is made from clay or other organic materials. The addition of pumice, sand or vermiculite up to half the volume of potting mix solves this issue.
  • Inability to drain perched water After water, it is crucial to let the plant drain. A drip tray or cachepot, or saucer will hold the liquid that’s left. It is a recipe for root rot and poor drainage if you do not take it out.
  • Place your anthurium in a dark, dim area – The ability of your plant to regulate the use of moisture and evaporation is assisted by the bright lighting. The moisture can stay within the soil a lengthy period of time under low light conditions.
  • Poor ventilation Maintaining your plant’s humidity and water levels under control is just as crucial as giving it the proper quantity of sunlight. Insufficient drainage can result when you put your anthurium in a humid or poorly ventilated space.

[3] Wrong Size Pot

If you place your anthurium in a pot that is too small or large in relation to its size the root rot could be a possibility.

If the container is too large the soil can hold lots of water. This can lead to concealed waterlogged areas which aren’t apparent from the outside.

The the root system of your anthurium could suffer when you use a pot that isn’t big enough.

Additionally, the soil can dry quickly and this could cause it to shrink and damage the roots.

In addition, to the harsh chemicals, minerals and heat, the roots inside a small container are more prone to contamination.

[4] Fungal Diseases

Root rot is caused by overwatering as well as fungal infections. This list includes but isn’t limited to:

The fungal infections can transmitted or affect your anthurium through a variety of ways, for example:

  • Infect garden tools such as pruning tools, scissors, and trowels.
  • Infected soil – This usually is spread to new plants when you are working with hands that have been soiled on leaves.
  • Reusing old, non-sterile pots

[5] Low-Temperature

Anthuriums are not fond of cold temperatures. This is evident most clearly when the temperature drops below the 50degF (10degC) mark.

If you think that winter is here and the slowdown in growth and activity is normal.

The survival strategy makes use of the least amount of water, energy, or other resources as is possible.

It is more likely that you overwater your anthurium since it requires less water which could cause damage to the root.

[6] Continuing to Irrigate During Dormancy Period

Like most species of tropical vegetation, the anthurium goes into go into dormancy during winter. This is usually the case in early winter months or in the late autumn/early spring.

This is intended to save energy and shield the plant from damage caused by cold.

Therefore your anthurium will require less water. If you don’t keep your plant hydrated and regularly, you’ll almost always suffer from root rot and overwatering.

How to save Anthurium From Root Rot

It is possible to save the plant in the event that the anthurium root rot is in its initial stages. If the disease has advanced too much it is important to consider propagation to help save the plant.

(1) Stop Watering

Root rot is often caused or worsened by excessively watering the soil. This is a major cause of the issue.

If you continue to water an anthurium that has root rot it will get worse over time.

First, stop watering the anthurium, so that it doesn’t dry out.

The earlier you stop irrigating, more likely it is that your anthurium will be able to survive.

Also, be sure to clean out any liquid that may have stored in the cachepot, drip tray, or saucer.

(2) Put Your Anthurium in a Shady Area

Root rot has already caused destruction to your anthurium. Don’t place the plant in direct sunlight to prevent scorch from the sun or damage to the leaves.

Soil, roots and leaves should be dried to stop the spread of infectious diseases in the shady region.

(3) Prune out the Infected Leaves and Other Parts

Next, you must eliminate all dead, dying or diseased leaves, stems, or any other plant material using attention.

Begin at the bottom and work your way up to at the very top cleanup.

The removal of any plant that isn’t green anymore or brown or black. This can help.

The pathogens that cause disease, such as fungi, are able to colonize dead or infected tissues. Also, they have a low chance of being able to revive.

Pruning off unwanted areas ensures that energy and resources are focused on healthy stems, leaves and other parts.

When pruning, it is essential to use a tool that cuts cleanly.

After every cut after each cut, cleanse it using the help of bleach or rubbing alcohol. solution. It is recommended to reduce your anthurium to a size of half.

(4) Unpot the Plant and Dry Out the Root System

The most effective method for dealing with root rot is to repot. This is why it is essential to be sure to check for root rot prior to when you start restoration work.

Additionally, repotting your anthurium may be stressful, particularly when you do it just prior to or at the start of the growth season.

Take your anthurium out of its container as soon as you detect any indications of root decay. If your anthurium is suffering from root rot, you’ll notice slimy roots that appear to be soft or darkened.

The root system needs to be thoroughly cleaned of old soil. Then, let the roots to completely dry before proceeding.

The root ball should be placed on a tarp, a cardboard magazine, or box in a shaded place.

If you let your plant outdoors for a night, the roots must be adequately aired to dry and airy.

Anthuriums that are smaller or older may only require 3-4 hours to reach.

(4) Trim off the Infected Roots

You can make use of a pair of sterilized , sharp scissors to remove the anthurium root that is infected or diseased to treat minor cases of disease.

(5) Treat Root Rot by using Fungicide

If the root rot isn’t completely destroyed the plant, your anthurium should have strong roots. They should be able to retain some form white color and the ability to move.

To ensure safety However it is essential to get rid of any pathogens that might exist.

To do this, I suggested applying a fungicide drench dip.

(6) Repot Using New Soil and Pot

Your anthurium must have been treated for root rot at this stage, and all affected roots must have been removed. The next step is to transplant your plant to a new location:

  • To prevent re-infections, you should use an unclean pot and a fresh pots and potting mixes. When handling any item, make sure to make sure you use sterile tools and clean your hands.
  • Select the right size pot. I suggest using a pot with one inch of soil around the plant. It must have drainage channels (a minimum of 3 holes).)
  • Check the drainage of your soil Check the drainage of the soil Anthuriums prefer coarse, well-drained soil that has an acidic pH. If you are planning to make a premix I would suggest starting with an orchid mix before adding peat moss and sand in order to increase drainage.
  • The pot should be filled halfway with soil that is fresh, and then place your plant in the pot. The pot should be filled with the remaining soil.
  • Make sure to water your plant regularly so that the soil in your pot is evenly wet. I typically mix 1 cup of hydrogen peroxide 3% in four cups water for irrigation. It serves two purposes to hydrate and protect against fungal infections!

(7) Avoid Fertilizer Until New Growth Starts to Appear

Make sure to feed your thurium with fertilizer only when you notice new leaves or additional signs of growth are evident.

Watering after Repotting

The process of rehydrating your anthurium once you have recovered from shock of repotting could take anything between a few days and weeks. Watch for the first signs of growth to show.

However, you shouldn’t water until the soil’s top layer has dried to the extent of. It is recommended to water about every week, while inside If it is possible. It could be reduced to every two or three days during summer.

Utilizing self-watering pots and irrigation at the base is perfect for anthuriums. Additionally, you can make use of rainwater, distilled or filtrated water.

Homemade Fungicide for Anthurium Root Rot


Cinnamon is most effective as a powder. It is a powerful antifungal and can also help to promote the growth of roots. When you are repotting your plant sprinkle the healthy roots.


It is possible to use chamomile in conjunction in conjunction with irrigation water. It’s a natural antifungal and safe for beneficial soil microorganisms.

Activated Charcoal

Not the most effective out of the bunch, however activated charcoal has good levels of antifungal properties. Be careful with it as its alkaline nature could alter the pH of soils.
