Good Morning Everyone , Does any one know what to do about black spots on my giant zinnias, they are blooming so nicely , But know some spots have taken over,I would appreciate any help, Thank You Margie moderator's note: added a more descriptive title to topic
If the black spots are on the leaves it is probably a fungal pathogen. You can spray them obviously, but try and remove as many of the leaves as possible and throw them in the garbage rather than compost them. A picture would probably help
