Help- is it Lilac Blight? Hi, I have this Lilac plant that I'm guessing is many years old. Last year the leaves started getting brown spots on them and then shriveled/dried up. I had read via Google that it was recommended to remove all the branches, etc. that were effected, so I did. It was also suggested to spray a copper fungicide on the plant early in the spring and I did that too. Things seemed to be going OK but I looked again the other day and saw more brown spots and yellowing. Also while this image doesn't show it, some leaves are curling up. Is there anything I can do to help it out? Also, not sure if it helps. I live in Missouri, zone 6b. We've had reasonable rainfall, so I have not independently watered it. It also gets full sun, and only has another lilac bush next to it (who also has similar issues). Thanks! Originally by u/alittlenerd on Reddit: https://tinyurl.com/2cqbjx74
