Q.Amelanchier Problem – What Is It And How Do I Treat It
Trunk has grey discoloured patches. Leaves have rusty circles on them. Leaves are green yellow and red and are falling from tree. I have removed juniper bushes from bed. Will my roses be affected?

It looks like fungal leaf spot. Roses are in the same family so they could be affected too. The light spots on the trunk could be powdery mildew.
