Hi Bonnie.

Milk may be basic, but when it sours, it becomes acidic hence the sourness of the milk

Norman, I thought milk was a base, similar to alkaline substances.

Rose growersn have known all along that bicarbonate of soda will raise the ph to reduce the mildew. Detergent helps the solution to stick, but I did not know it could work all alone. Skim milk also works by acidifying the leaves to the point mildew cannon not live.

You should probably fix the typo in the sentance near the end of the article (copied below):

“…do take precautions now to breathe the small droplets of spray (wear appropriate masks)”
