Hi Ethel from the sunny US Okanogan! I'm just south of Midway, BC if you know where that is or 30 miles SW of Grand Forks. We started to have a light coating of mildew on the wild roses and snow berries but the leaves are dropping for fall now. A solution of 1 tsp baking soda to 1 quart of water and up to 1 tsp liquid dish soap sprayed regularly can help control mildew and black spot. I also read that regular washing of the leaves will help but to do it so they can be dry before the cool night air. I hope you find this helpful.
