I have tried milk and water for mildew on my roses, and it did work. Adding the other ingredients would probably make it work better. We haven't had any fungal issues here this year, we don't even have slugs or snails due to very dry conditions, but I will save this recipe for when we get rain again...if I live that long.

I used milk on a honeysuckle covered with powdery mildew and it cleared it right up. I agree the recipe with the additions is a keeper.

I will try this too. Thanks for sharing

no issues with black spot so far on my new baby shrub roses or on the "knockout" roses in the front bed... but I'm planning on putting in some more shrub roses and a couple of climbers, plus there are several other plants that get bad mildew some years. The mildew is more unsightly than really damaging, but this would be an easy way to knock it back!

Thank you!!
