|My house plants have a white fungus. How do I treat This and what is the cause?????
|If it is a white powdery growth on the foliage and stems, it is probably powdery mildew. This is caused by environmental conditions, typically cool nights with high humidity and poor air circulation. I would suggest rinsing the plants to clean them (use tepid water) and place them in a location with better air circulation. (If you can't move them, try using a very small fan at lowest speed, you want to move the air slightly and not create a big, windy draft.) Take care not to over or underwater them, and do not crowd them. I hope this helps.
