Re: Powdry Mildew on amalanchier
Shoot User
I had the same problem with mine this year (an many others). I managed to prevent further leaves from mildew by spraying the leaves on both sides with a mix of water and 20% skimmed milk (full fat not good for plant). Apparently it should be done weekly to keep mildew at bay. I only did it once but was put of by the milky smell and the fact that it left a very slight white stain on each leaf (though not as bad as the mildew itself).
Despite only applying once it did seem to stop the spread and a week of windy weather and watering at the base probably helped get things back on track. In future I will try the less smelly version which uses a teaspoon of Bicarbonate of Soda in about a litre of water sprayed on.
Hope this helps.
