Disease- yellow leaves, brown and black spots
I hope someone can help me. Late last summer I discovered a disease was rampant in my garden. It affects everything- rhodies, azaleas, escallonias, laurels, magnolia, madrona, even ivy. I cleaned up all the gardens,cut the plants way back, and sprayed Neem oil and another anti-fungal. Now it has come back again full force. It seems to come from the ground up. The plants are otherwise very healthy, until the leaves turn yellow, sometimes mottling before they are fully yellow. Many of the leaves also have brown or black spots/areas. I am really scared I will lose all the plants and some of them are very mature. I have not been able to figure out how to include my photos in this post but I do have digital photos. If anyone is willing to take a look at them, I can email the photos. Thank you.
