Powdery mildew on Dahlias

[Gemma]

To fight the Powdery Mildew on my Dahlias I've been spraying both sides of the leaves with Milk and water at 1 to 2 parts ratio. Is there another home remedy for Powdery Mildew?

Have you tried the baking soda spray? 1 heaping tablespoon baking soda, 1 tablespoon orange oil or horticultural oil or mineral oil and 1 tablespoon of molasses per gallon of water.

Thanks @Chuck I haven't tried the baking soda, would olive oil work?
...and where can I find "molasses" ? (I have no idea what that is )

I don't know if olive oil will work or not, it may be too thick. Mineral oil or baby oil will though. Molasses can be found in small quantities at the grocery store usually close to where the honey and baking goods are stored. Read about molasses in the Organic Gardening forum on this site. Look for Molasses the Wonder Drug thread.

Will do, thanks for all your help!

Remember to get the undersides of the leaves.

Really, you get powdery mill dew on them. been avoiding starting them because of the pain of lifting and storing. now that I know that extra they give, I can now say, they are off my list totally. have enough to bother with, with what I have.

The tubers are edible.

how do they taste? got a recipe? think there is enough edibles around for me, that is what my hips tell me anyway.

I've never eaten them. Apparently they're bland and starchy.
