Root Rot (Overwatering)

Excessive moisture prevents oxygen from reaching the roots, causing them to decay and making it impossible for the plant to transport water to the leaf tips.

Common

How to confirm: Gently lift the plant from its pot to check if the roots are dark, mushy, or emit a foul odor.

1 Immediately inspect the roots for mushy, dark, or foul-smelling decay and trim away any damaged sections using sterilized tools.

2 Repot the plant in a fresh, well-draining medium like a mix containing perlite to improve aeration and prevent future waterlogging.

3 Use a moisture meter to monitor the soil and ensure you only water when the top inch of soil is dry, preventing further overwatering.
