Question
I have a rosemary plant that I've managed to save for 2 yrs now.  Recently I noticed a white, powdery mildew/fungus growing on some of the leaves and it is spreading.  When I touch it it almost feels a little waxy.  Plant is not looking so good.  I was about to put it outside for spring and hope that sunlight kills some of mildew.  Any other ideas ??

Answer
Pete:
Yes! do move outdoors in full morning. The stuff is powdery mildew and rosemary will get it indoors without proper ventilation; not enough sunlight; too much water or not enough.
?  POWDERY MILDEW on Roses, Rosemary and others: (1) teaspoon of  Baking Soda to (1) quart of water. (3) tablespoons to (1) gallon of water.Spray under and on top of leaves every 3 days for 9 days. Then just watch plant for return. Wash off leaves before using in food. Not toxic.
