Root and crown rot, Rhizoctonia solani and Pythium spp.
Symptoms appear as wilting and general droopiness of the foliage and are nonspecific.
This flaccid appearance is often accompanied by browning and rotting of the roots and the crown. Yellowing and death of the outer leaves follows, until finally the entire plant is dead. Control can be achieved by using a sterile potting mix and clean pots. It is also helpful to avoid overwatering, especially in the crown area of the plant. It is important to never let the plant sit in standing water.
