Root rot is a common issue in Monstera plants, caused primarily by overwatering or poor drainage. From the plant's perspective, excessive moisture suffocates the roots, depriving them of oxygen and creating an ideal environment for harmful fungi like Pythium or Phytophthora. The roots turn mushy, brown, or black, and the plant struggles to absorb nutrients, leading to yellowing leaves, stunted growth, and eventual collapse if untreated.
Monstera plants exhibit several signs when suffering from root rot:
Step 1: Remove the Plant from Its Pot Gently lift the Monstera and shake off excess soil to inspect the roots.
Step 2: Trim Affected Roots Using sterilized scissors, cut away all soft, discolored roots. Healthy roots should remain intact.
Step 3: Disinfect the Root System Soak the remaining roots in a diluted hydrogen peroxide solution (1 part peroxide to 3 parts water) or a fungicide to kill lingering pathogens.
Step 4: Repot in Fresh Soil Use a well-draining potting mix (e.g., a blend of peat, perlite, and orchid bark) and a pot with drainage holes to prevent future waterlogging.
Watering: Allow the top 2-3 inches of soil to dry before watering. Monsteras prefer slightly moist but not soggy conditions.
Light and Humidity: Provide bright, indirect light and moderate humidity to support recovery. Avoid direct sunlight, which can stress the plant further.
Fertilization: Hold off on fertilizing until the plant shows new growth, as damaged roots cannot absorb nutrients efficiently.
After repotting, monitor the Monstera closely:
