Common Symptoms of Peace lily root rot

Peace Lily Root Rot

When the roots begin to decay, they are plainly visible. The following are some of the most typical signs of peace lily root rot:

Leaves start Wilting

Wet leaves are unable to absorb as many nutrients from the air, leading to their eventual death. One of the most common reasons for wilt is overwatering. When plants are overwatered, the roots rot and can’t absorb water and nutrients, starving the plant.

Always check for root rot if you see your plant’s leaves drooping or wilting.

Leaves turn yellow

The leaves become a golden yellow in the fall. This is widely acknowledged as the primary driver of unnecessary irrigation. If you see any yellowing of your plant’s leaves, it’s time to do a thorough root inspection.

Stunted Growth

Stunted Development is often brought on by root rot. This often occurs in locations with inadequate drainage after the roots have been exposed to damp soil.

You must provide enough light and water for your peace lilies (according to the need). Your plant life will flourish and flourish if the soil drains adequately.

The appearance of Black Spots

Those black spots on your peace lily probably aren’t the first symptom of root rot. They may indicate that your peace lily has suffered from or is at risk of root rot. Peace lily leaves develop black dots surrounded by a yellow tinge when bacteria and diseases harm the young roots of the plant.

The soil produces a Bad smell

Some soils have a pungent odor that may be detected by the human nose. You can tell your peace lily has root rot if it starts to smell bad. Yellowing leaves and wilting stems are often the first signs of root rot.

Causes of Root rot in Peace lily

Root rot in peace lilies may be caused by a number of factors. Root rot may occur for many different causes.

Low Light

Although peace lilies can tolerate low light, their delayed development is a direct result of the lack of light. Because photosynthesis and metabolism slow down under low-light conditions, drying out the soil take longer. Wet soil is the primary cause of pests and fungi because it harms plant roots. read my article do peace lily need sunlight for more information


The peace lily is a delicate plant that does best in soil that is just slightly damp, but too much water can kill it. A peace lily in the yard requires regular but not too abundant watering.

The growth of peace lilies is greatly aided by consistent watering. But if you overwater, the roots will rot. If the plant does not get adequate oxygen, its growth will be stunted. Because of this, the plant’s root system finally fails and the plant dies.

Poor Drainage System

Even if you give your peace lilies the recommended amount of water each time, it won’t help if the pot isn’t split correctly and the excess moisture has nowhere to go.

If you leave too much water in the container, the soil will get soggy and the air will be unable to circulate freely. Because of the drainage mechanism, the roots in this planter won’t rot in the soil. Root rot in peace lilies may be prevented by using a self-watering container with drainage holes.

Large Pot Size

There are a number of good reasons why you may want to try growing your plant or seedling in a larger-than-usual container. A larger volume of potting material and water may be held by the peace lily. Because of this, the root rot of peace lilies is the most pressing issue.

Peace Lily Root Rot Treatment

causes of root rot in Peace Lily

If you have a peace lily and suspect it has root rot after reading about the signs above, take action immediately! The root rot of your plant might be treated in one of two methods.

  • Report peace lily to a new pot or container with adequate drainage holes.
  • Use self-watering pots that have air holes.

Repotting the plant

The fungus may be eradicated from the plant by repotting it into a new, clean, and dry container.

If the roots of your peace lily are injured, you should repot the plant.

If your peace lily has developed root rot, you may repot it as follows:

  • You should carefully remove your peace lily from its container by holding the main stem.
  • After removing your peace lily from its container, gently rinse it under running water to remove any remaining dirt.
  • Remove any damaged leaves or branches from your plant. Do this even if you can’t see any issues; the increased light and airflow your plant will get as a result will help it recover.
  • The affected roots may be sprayed with a fungus killer or soaked in bleach water to kill any remaining bacteria.
  • Open the drainage holes in the fresh, empty pot. It’s important to remember to fill up the bottom of the hole with some of the stones. This will prevent the drains from becoming blocked.
  • Put in new, well-drained potting soil until it fills about a third of the container.
  • Place the Peace Lily in the container and fill the surrounding area with new dirt gradually.
  • Before planting a peace lily, make sure the earth is just slightly damp. After repotting, the peace lily should go somewhere it may bask in direct sunshine for at least six hours a day. The peace lily plant might experience stress if exposed to too much light at this time, so be mindful.
