Powdry Mildew on amalanchier

Hi, I have a small hedge of amalanchier. They have plenty of space around them and they have been watered regularly. All the planst have been infected with powdery mildew. What is the best course of action to take?

Thanks

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.

Thank you for your response. I was not aware that milk could be used. I will try it and let you know how I get on.
