Root Rot is typically happens when the soil does not dry out enough between waterings, or if the roots sit in water for an extended period of time. The excess water and moisture can eventually suffocate the roots, causing them to begin to rot.
If you think your plant is experiencing root rot, the best way to tell for sure is to remove the plant from the pot and examine the root ball. If any of the roots look brown and squishy, or limp, this is likely root rot. You should gently remove all of the unhealthy roots from the plant, and then repot the plant in fresh potting soil. Over time, the health of the plant should start to improve.
