How Do I Recognize and Prevent Root Rot in Soil?
Root Rot/Stem Rot is a common disease that affects hydroponics, soil and soilless systems. Growers running soil and soilless systems should be aware of the environment that pythium thrives in, and actively improve their room/planting site conditions. Soil growers do not have the luxury of looking at their roots, so they should anticipate problems and recognize the early symptoms of pythium infection. Root/Stem rot is almost impossible to treat because it is systemic (internal) in nature. Even in an advanced stage root rot may go unnoticed, with above ground growth appearing normal. Growth and yield however, can be drastically reduced. Think of pythium as flesh eating disease for plants! Some external symptoms to look for: * Slow growth for no apparent reason * Wilting leaves. (Narky) Often the top of growth shoots will also become limp and buckle over * Leaves turn yellow starting at the bottom-most node, from the leaf tips inwards * Reddening root collar, turning to a brown/black ring
