Hello I am hoping someone can help us. We recently JUST planted this Beauty of Moscow Lilac, literally 3 days ago. We live in Chicago so the plant is good in our zone. We had some sun and we watered it since we planted. Today I noticed these black spots!!! Is this blight, or something else??! Does anyone know what to do from here to save this new bush?

I don't grow lilacs but I will say your plant needs time to acclimate, and never water the leaves. I don't know where you got it, but I'm sure it needs time to get used to it's new home...especially if it was nursery grown.
