Root rot.
A general term for decay and failure of roots, often associated with prolonged wetness and disease organisms.
What it means for your plants
Inspect firmness and tissue integrity rather than color alone. Remove the conditions that keep roots oxygen-starved and assess how much healthy tissue remains before choosing a recovery approach.
IN PRACTICE
A wilting plant in wet mix with soft, collapsing roots needs a different response from a thirsty plant in dry mix.
