Have you ever had problems with mildew and temperature control on your plants? How did you take care of this problem?
My view is that mildew being a fungus growth, its seeds or spored are ever present in the atmosphere; and when a relaxed condition of the plant ensues, the minute germs find a suitable place for their development in the enfeebled leaf. Therefore I believe that anything that impedes the flow of the sap places the plant in the condition fitted to develop mildew. All care should be taken to avoid great variation of temperature. I know you may not have control over mother nature, and her ever changing temperatures, but evenly moist soil will also keep plants from becoming relaxed and or wilted with mildew.
