begonia mold?

| I have a number of begonias, angle wing and others that have been great for years. This year they are all getting a white moldy substance on the stems and as spots on the leaves. What could this be? |

| Probably mildew. A very helpful begonia expert who used to post here recommended spraying very lightly with Lysol. Also helps to increase air circulation, perhaps with a small fan. Some people use baking soda, but I don't remember the concentration--I just keep the Lysol spray can handy. I think it scares 'em--haven't had a problem since I started keeping it on a stand by my lights. |

| I heard begonias can develop powdery mildew. You could search for powdery mildew and see what remedies are recommended for this. I never heard about using Lysol but I'll have to look into this (interesting)! |

| the lysol is very effective, as is an occasional dusting/spraying of sulfur (stinky). you'll have to get the aerosol can, though. -ming |

| Should I dilute the lysol? If so, at what rate? |
RE: begonia mold?
| | |
| as above, you should buy the lysol that comes in aerosol cans--which won't require diluting. just spray it straight. -ming |

| I don't know if this information will be of any use to you or not, but several years ago I got mildew on my african violets every winter. My daughter gave me one of those small fountains suitable for a room. I run it constantly and haven't had mildew since. Why this worked I don't have a clue. Reason tells me more moisture in the room should produce more mildew, but its just the opposite. |
