How to Repot a Peace Lily with Root Rot

Symptoms of Root Rot 

Symptoms of root rot in a peace lily include the following.

Wilting Leaves

Wilting leaves are one of the earliest indicators of root rot in a peace lily. Even when properly hydrated, the plant may seem droopy. This withering happens because the injured roots cannot absorb water and nutrients adequately. 

As a result, the leaves don’t get enough water, causing them to droop and become limp. Even if the peace lily is watered, the withering will continue since the root structure is damaged.

Yellowing Leaves

The peace lily’s leaves may become yellow as root rot advances. This discoloration is frequently caused by the plant’s inability to absorb nutrients due to damaged roots. The roots are critical in taking nutrients from the soil and delivering them to the plants. 

When roots decay, they become less efficient, resulting in a nutritional deficit in the plant. As a result, the leaves brilliant green hue fades and turns yellow. This is a definite indicator that the peace lily has root rot.

Brown or Black Roots

When investigating the roots, you may discover they have become dark or black rather than the normal white tint. This discoloration indicates root rot. Healthy roots should be solid, light in color, and free of black patches. 

When root rot takes hold, the roots begin to degenerate. Because of fungus or bacteria, they discolor, turning brown or black. This color is caused by the rotting process occurring in the root system.

Soft, Mushy Roots

The roots become soft and mushy as a result of root rot. The texture of healthy roots should be solid, providing support and stability to the plant. When root rot starts, the roots deteriorate and become weak and mushy. 

When you gently compress root rot-affected roots, they may feel fragile and may even crumble. The mushy feel indicates that the roots are deteriorating and no longer performing their jobs correctly.

Stunted Growth

Stunted growth is one of the indications of root rot in peace lilies. The plant’s growth is hampered because the injured roots cannot adequately absorb and transfer nutrients and water. 

The plant’s capacity to generate new leaves, stalks, and flowers is hampered by a shortage of necessary materials. You may observe that the peace lily seems reduced in size compared to healthy plants of the same age or that it struggles to develop new growth even when conditions are good.

Foul Odor

Root rot can produce a distinct bad stench from the damaged peace lily. The presence of decomposing organic materials and the activities of bacteria and fungus add to the unpleasant odor. The odor is frequently characterized as musty, moldy, or rotting. 

If you notice a strong and unpleasant odor emanating from the potting soil or the root system, this indicates root rot and the breakdown of the plant’s tissues.

Leaf Drop

Peace lilies may demonstrate substantial leaf loss in the advanced stages of root rot. The plant’s leaves cannot maintain themselves as the root system deteriorates and cannot offer adequate food. 

The leaves may fade, wilt, or acquire brown blotches before falling off. Leaf drop indicates acute stress and suggests the plant is battling to survive, even if it receives appropriate water.

Slimy or Oozing Roots

The damaged roots may become sticky or leaking in some cases of root rot. This sliminess is frequently induced by excess moisture and microbial activity. 

When manipulating or inspecting the root system, the roots may emit a sticky or mucous-like fluid. The sliminess impairs the root’s capacity to absorb water and nutrients, worsening the illness.

Overall Decline

Root rot can cause the peace lily’s overall health and attractiveness to deteriorate. The plant may display various distress symptoms, such as pale or discolored leaves, weaker stems, and an overall ill look. 

The leaves brilliant green hue may fade and seem drab or uninteresting. The plant’s vigor declines, making it more vulnerable to diseases and pests. If left untreated, root rot can gradually weaken the plant and finally kill it.

Causes of Root Rot

Various reasons, including those listed, can cause root rot in peace lilies.  

Poor Drainage

When cultivated in soil that lacks appropriate drainage, peace lilies are prone to root rot. When extra water cannot escape the soil, it gets waterlogged, creating a saturated environment surrounding the roots. 

Excessive wetness inhibits oxygen from reaching the roots, resulting in oxygen deprivation and the growth of anaerobic bacteria and fungi that cause root rot.

Stale Soil

Using old, compacted soil that has lost its nutritional value might contribute to peace lily root rot. Soil can become compacted over time, diminishing its ability to hold water and provide appropriate aeration for the roots. 

Furthermore, the soil’s nutritional concentration may diminish, leaving the peace lily lacking vital nutrients for proper growth. As a result, the roots are more vulnerable to fungal infections that cause root rot.

Fungal Infection

Infections caused by fungi typically cause root rot in peace lilies. Fungi that flourish in damp circumstances, such as Pythium and Phytophthora, can infect the roots. These fungi can enter the plant through wounds or natural holes in the roots, where they can then increase and cause the roots to rot. 

Overly moist or humid surroundings encourage fungal development and raise the danger of root rot. Overwatering or insufficient ventilation around the roots can worsen fungal infections and hasten the development of root rot.


Overwatering is a common cause of root rot in peace lilies. When the plant is given more water than it requires regularly, the soil gets saturated, depriving the roots of oxygen. This produces an ideal habitat for fungal development, which leads to root rot. To avoid this, let the top layer of soil dry between waterings and ensure appropriate drainage in the container.

Lack of Proper Light

Inadequate light can weaken peace lilies and render plants susceptible to root rot. The plant’s development slows in low-light circumstances, and its defensive systems weaken, allowing diseases to infiltrate the roots easily. Providing appropriate, bright, indirect light aids in maintaining the plant’s vitality and resistance to root rot.

Contaminated Tools or Soil

Using contaminated instruments or reusing pathogen-infested soil might transmit dangerous bacteria to the roots of the peace lily. Root rot can be caused by bacteria and fungi found in contaminated instruments or soil. To avoid this, clean and disinfect gardening equipment before using it, then repot or top-dress the plant with new, disease-free soil.

High Humidity

Excessive humidity can promote the development of root rot in peace lilies, which require moderate humidity levels. When the air is humid, moisture escapes from the soil more slowly, resulting in persistent wetness around the roots. 

This produces a favorable environment for fungal development and root rot. Proper air circulation, ventilation, and humidity control can all help avoid root rot.


Fungus gnats, for example, can indirectly lead to root rot in peace lilies. These pests can cause root damage, resulting in sores that allow fungal diseases to enter. 

Regular pest inspections and management procedures, such as utilizing sticky traps or spraying organic pesticides, can help protect the plant from root rot caused by pest infestations.

How to Repot a Peace Lily with Root Rot

You will need the following to repot a peace lily with root rot.

A New Pot That Is One Size Larger Than the Current Pot

Choose a big pot to accommodate the peace lily’s future root development. This prevents wasting more soil or fosters adverse circumstances, allowing the plant to establish itself in the new container.

Fresh Potting Soil

Select a well-draining potting mix made especially for houseplants or make your own. Peat moss, perlite, and compost can be combined in equal amounts to create an appropriate homemade combination. 

Perlite encourages ventilation and reduces soil compaction, peat moss aids in moisture retention while allowing for appropriate drainage, and compost offers vital nutrients for plant growth.

A Sharp Knife or Pruning Shears

During the repotting procedure, these instruments are necessary to remove dead or damaged roots. Make clean cuts to remove brown or black roots to prevent additional harm. Sanitizing the instruments before use is essential to halt the spread of dangerous germs.

A Fungicide

Choose a fungicide appropriate for indoor plants and adhere to the label’s directions. A fungicide aids in the prevention of root rot and the management of fungal diseases. When repotting a peace lily, adding it to the soil helps protect the plant’s roots and reduce the possibility of additional harm.


Now, follow the step-by-step instructions for repotting a peace lily with root rot. 

1. Remove the Peace Lily From Its Current Pot

Support the plant’s base while you carefully remove the plant from the pot it is currently in. If the roots are firmly bound, use a tool or the pot’s sidewalls to tap the root ball loose. Be careful to prevent further harm to the roots.

2. Loosen the Roots of the Peace Lily

Gently untangle and loosen the roots once the plant has been removed from the pot. Remove any clumps or compacted earth wedged between the roots and gently brush off any extra soil that may have accumulated. The roots can stretch out in the new container and be encouraged to generate new growth.

3. Cut Away Any Dead or Damaged Roots

Trim off any brown, black, mushy, or injured roots using a sharp knife or pruning scissors. Make precise cuts to get rid of the damaged regions. This action encourages the growth of healthy roots and stops the spread of root rot.

4. Report the Peace Lily in the New Pot

The top of the root ball should be level with the pot’s rim when you place the peace lily in the new container. If necessary, reposition the plant to ensure it is standing straight up and centered in the container.

5. Fill the Pot With Fresh Potting Soil

The fresh potting soil mixture should be added to the remaining area in the container. To anchor the plant, gently push the earth down around its roots. When watering, leave approximately an inch between the soil’s surface and the pot lip to prevent overflow.

6. Water the Peace Lily Thoroughly

After popping, give the peace lily plenty of water until the drainage holes in the pot are full. This promotes soil stabilization and guarantees that the plant gets enough water. Allow all of the extra water to drain away.

7. Apply a Fungicide to the Soil to Prevent the Root Rot From Spreading

Apply the right quantity of fungicide to the soil surface by the label’s directions. This process aids in the management of any lingering fungal spores and stops the root rot from spreading to the peace lily that has just been repotted.


How often should I repot my peace lily?

Repotting peace lilies is often beneficial every one to two years or when plants become root-bound. Repotting gives the plant access to new soil, encourages strong root development, and keeps it from being too crowded in its container. 

To deal with root rot, your peace lily must be repotted immediately if it exhibits symptoms like drooping leaves, yellowing foliage, or squishy roots.

What should I do if my peace lily has root rot?

To rescue the plant, you must act quickly if your peace lily develops root rot.

To repot the plant, according to the directions provided in this article. Starting with the afflicted roots, remove any brown or black roots and make sure your cuts are clean. 

Repot the peace lily next in a brand-new container with brand-new potting soil. To stop the spread of root rot, give the plant plenty of water and spray with a fungicide. The likelihood of the peace lily recovering after repotting will be increased by providing proper care and surroundings.

Should I cut roots when repotting peace lily?

Trim away any damaged or dead roots before repotting a peace lily. These roots could be mushy, brown, black, or decomposed. Root rot may be stopped from spreading by cutting off the damaged roots, promoting the development of new, healthy roots. 

However, it’s important to avoid removing good roots needlessly because they are essential for the plant’s general health as they absorb water and nutrients. When repotting, only pull off roots that are injured or rotting.

Can you repot a plant with root rot?

Repotting a plant with root rot is an option. To properly handle the root rot issue, repotting is frequently required. Repotting enables you to remove the damaged roots that are the source of the root rot and provides the plant with a new, nutrient-rich environment to heal. 

Removing the decaying roots and replacing them with nutritious soil and appropriate drainage can improve the plant’s chances of survival and development.

Why is my peace lily dying after repotting?

After repotting, a peace lily may struggle or seem to be dying for some reason. The shock from the repotting procedure is one frequent cause. The plant could take time to adapt to its new surroundings and set down roots. 

Inadequate watering after repotting can also cause problems since the lily’s roots may need to absorb water more efficiently. The plant’s health can also be impacted by insufficient light levels or abrupt changes in lighting conditions. 

After repotting, give the plant the care it needs by giving it the right amount of water, putting it in a spot with the right amount of light, and giving it time to become used to its new container and soil.
