Root Rot

Identification

Yellow leaves and stunted growth are common symptoms of root rot. Because these are also symptoms of other diseases, be sure to check the plant's roots before assuming it has root rot. Soft, brown roots, instead of firm, white roots, are a surefire sign of root rot.

Damage prevention

Physical control

Gently dig up affected plants. Inspect their roots; if the entire root system is brown and mushy, the plant is not salvageable. If some of the roots are still healthy and white, replant it in fresh soil with better drainage. Before replanting, gently clean the roots under running water, and cut off all brown, mushy roots. Be sure to sterilize your scissors after using them on infected plants.

Chemical control

Chemical control is not recommended for root rot.
