When I detect root rot in a Monstera, I take immediate, decisive steps to mitigate the damage and set the stage for recovery.

1. Isolation of Affected Plant

My first action is to isolate the affected Monstera from other plants to prevent the spread of disease. I carefully remove it from its current location and designate a separate space where I can address the root rot without the risk of infecting other nearby plants.

2. Stopping Watering Routine

Subsequently, I suspended the watering routine for the affected Monstera. This pause in watering is critical as it helps halt the progression of the root rot, which thrives in overly moist conditions.

It allows the soil to dry out slightly, which is essential before I proceed with further treatment steps.

Treatment Procedures

When addressing monstera root rot, it’s important to act swiftly and meticulously. I will guide you through the necessary steps to give your plant the best chance at recovery.

1. Root Pruning

The first step in the treatment of root rot is to carefully remove the plant from its pot and examine the roots.

I use clean and sharp scissors to trim away any roots that are brown, black, and soft to the touch, which are indicators of rot. It’s essential to keep only the firm, white roots, as these are healthy.

2. Soil Replacement

After pruning the unhealthy roots, I prepare for repotting by completely replacing the soil. This step is critical because old soil can harbor pathogens that cause root rot.

I select a fresh, well-draining potting mix specifically formulated for aroids. Before placing the monstera back, I ensure the pot is cleaned and free of any potential contaminants.

3. Use of Fungicides

As a preventative measure, especially if the root rot was severe, I treat the trimmed roots and new soil with a fungicide. Fungicides such as neem oil mixed in a soil application can help in preventing future occurrences of fungal root rot.

It’s important to follow the instructions on the label for the correct dilution and application method.
