I just planted two rose bushes, but in the day between getting them at the store and getting them in the ground, they appear to have gotten some powdery mildew on them! I don't really know what to do, since it's around the base of the plant...
I got this off of the rain gutter grow system face book page I have not tried it yet. But if I find a problem I will try it.
Fungicide Recipe – Natural Cure for leaf mold or powdery mildew
2 Tblsp Baking Soda dissolved in 8 oz glass of hot water
1 Tblsp Dawn dish detergent
Empty Quart Spray Bottle
Dissolve 2 Tblsp Baking Soda in an 8 oz glass of hot water.
Pour the mixture into an empty Quart spray bottle.
Add 1 Tblsp Dawn dish soap to the empty spray bottle.
***Fill the spray bottle the rest of the way with water.
Shake every time before using because you will usually still have some
Baking Soda settle in the bottom. This is a fungicide, but also kills
bugs as an added bonus. You can also use this as a household cleaning spray,
kitchen counter tops, bathroom etc.
NOTE***: The hot water is only used to dissolve the baking soda.
So don’t spray hot water on your plants. Let it cool before spraying.
