Oedema Disease - Houseplants Disease and Control

Oedema Disease

Oedema also called Corky Scab is characterized by hard corky growths on the underside of leaves; this is the houseplants response to waterlogged soil coupled with low light intensity. In these conditions, the plant will rapidly absorb water from the soil but since the available light is little, most of the water cannot be used up as quickly which results in the cells bursting. The hard corky spots are due to the burst plant cells.

Control:
  • Remove badly affected leaves; they will not recover. Move the plant to a better lit spot and reduce frequency of watering.
