Monstera plants, with their eye-catching, tropical leaves, have become popular choices among houseplant enthusiasts. However, these beautiful specimens can suffer from root rot, a condition that can be detrimental to the plant’s overall health. In this article, readers will discover the key steps to diagnosing, treating, and preventing monstera root rot to keep their plants thriving.

Identifying Monstera Root Rot


Identifying root rot in your Monstera plant can be crucial for its survival. Here are some common symptoms to look for:

  • Leaf yellowing: If you see a pale color or yellowing creeping over some of the leaves, it might indicate that something is wrong with the roots of your Monstera.
  • Dark and mushy stems: This is a significant indicator that the roots are rotting and have spread the infection to other parts of the plant.
  • Drooping leaves: Taking your Monstera out of its pot for a root inspection may cause it to droop its leaves temporarily. However, if your plant is consistently drooping without an explanation, it could be a sign of root rot.


Understanding the causes of root rot in Monstera plants can help prevent the issue in the future. Common causes include:

  • Overwatering: This is the leading cause of root rot. An overly saturated soil causes the roots to suffocate and not receive the oxygen they need, leading to the development of a rotting environment.
  • Poor drainage: If the soil does not drain adequately, water will accumulate and cause the roots to rot.
  • Contaminated soil or pots: If you have recently repotted your Monstera or introduced it to new soil, ensure that neither the soil nor the pot contains bacteria or other harmful agents that could lead to root rot.

Preventing Root Rot

Proper Watering Techniques

To prevent root rot in monstera plants, appropriate watering techniques are essential. Overwatering is a leading cause of this issue, so be mindful of your plant’s needs. Check the soil moisture before watering and only proceed when the top two inches of soil are dry. When watering, provide enough water until it starts running out the drainage hole in the bottom. This helps ensure your plant receives adequate moisture without saturating the roots.

Drainage and Pot Selection

Good drainage is another critical factor in preventing root rot. When selecting a pot for your monstera plant, opt for one with sufficient drainage holes. This allows excess water to escape and prevents the soil from becoming waterlogged. Additionally, choose a pot that offers suitable space for your plant’s roots to grow while ensuring it’s not too large, as this could result in water retention and contribute to root rot.

Soil Composition

Using the right soil mix can help prevent root rot in monstera plants. Choose a well-draining and aerated soil that does not retain excessive moisture. A mix containing peat moss, perlite, and/or bark chips can provide the necessary drainage and aeration. This optimal soil composition allows the plant’s roots to access oxygen and water without being exposed to stagnant conditions that promote root rot.

By adhering to proper watering techniques, selecting pots with suitable drainage, and using the appropriate soil composition, you can effectively prevent root rot and maintain a healthy monstera plant.

Treating Monstera Root Rot

Root rot can cause severe damage to your Monstera plant if not treated promptly. Here are some steps you can follow to treat Monstera root rot effectively.

Removing Damaged Roots

First, gently remove your Monstera from its pot and shake off any excess soil to inspect the roots for signs of rotting. Brown, mushy roots with a foul smell indicate root rot. Carefully trim away the affected roots using a clean, sharp pair of scissors or pruning shears, ensuring that only healthy, white roots remain.

Sterilizing Tools

It’s crucial to sterilize your tools before and after use to prevent the spread of pathogens. You can soak your scissors or shears in a solution of one part bleach to nine parts water for approximately 30 minutes. Rinse the tools thoroughly with water afterward to remove any bleach residue.

Repotting and Soil Replacement

Choose a clean pot with proper drainage holes and consider using a soil mix that promotes excellent drainage and aeration. A blend of peat, perlite, and orchid bark in equal parts is an appropriate medium for Monstera plants.

To repot your Monstera, place a layer of fresh soil mix at the bottom of the new pot, and position the plant in the center of the pot. Carefully fill the gaps around the plant with the soil mix, ensuring the roots are well covered but not compacted. Water the repotted plant thoroughly, allowing excess water to drain out of the drainage holes.

Monitor your Monstera plant’s recovery by checking its new growth and overall health. Regularly assess the soil moisture and wait until the top two inches of soil are dry before watering the plant. Maintaining proper watering habits, adequate drainage, and an appropriate potting medium will help prevent future occurrences of root rot.

Recovery and Post-Treatment Care

After treating your Monstera for root rot, it is crucial to provide proper care to ensure a successful recovery and prevent future occurrences.

Monitoring Water and Soil

Overwatering often leads to root rot, so closely monitor the Monstera’s water and soil conditions. Ensure that the soil remains consistently moist, like a wrung-out sponge, but not soggy or wet to touch. Remember that the frequency of watering will vary depending on factors such as humidity and room temperature. Invest in a moisture meter if necessary, to accurately measure the soil moisture levels.

Beyond water management, improve soil drainage and aeration to prevent waterlogging. Use a well-draining soil mix, and add perlite, coarse sand, or bark to enhance aeration. Regularly check for proper drainage by inspecting the pot’s drainage holes and clearing any blockages.

Adapting to New Growth

After treating root rot, it is essential to trim affected leaves and stems, as this helps the plant focus its energy on recovery and new growth. Pruning also prevents further spread of fungal infections. Monitor new growth and signs of improvement, such as healthy root development and the emergence of new leaves.

During the recovery phase, be mindful of the plant’s nutritional needs. Provide adequate amounts of light, and consider using a balanced fertilizer to encourage robust growth. Be cautious with fertilization, as excessive nutrients may stress the plant and make it more susceptible to diseases.

By following these post-treatment care guidelines, you significantly increase the chances of your Monstera’s recovery and prevent future instances of root rot.
