Root rot is a fungal disease in the soil blocking the plant roots ability to access oxygen. Yellowing and wilting leaves and stems is the indicator root rot is present. The roots will be blackened and have rotted into a mushy mess.
Main cause for root rot is over-watering of the plant. Either the water is not draining properly or the pot plant is sitting in a pool water at the bottom of the cover pot.
Once root rot is present it is hard for the plant to recover. Your best chance for recovery is to remove affected areas and re-pot remaining plant into fresh potting mix with proper drainage. Water plant when the soil is dry. Outbreaks can also be controlled by repeat applications of Searles Root Rot Systemic Fungicide.
