Pictures might help; instructions for posting them are in Helpful Tips and Suggestions for new members.

Lots of things could be chewing the leaves. Look closely, especially at the undersides, see if you can spot the culprit. If you have lots of big holes in the leaves and you don't see anything in the daytime, come back late at night with a flashlight and check again, it might be slugs.

The black spots are most likely some kind of fungal disease.

Re what to do.... if the damage isn't real significant and isn't threatening the immediate survival of the plants, one possibility is do nothing. Zinnias are annuals. They will likely be done inside a month or so anyway.

One of the only spots that I can grow zinnias in my garden is among the iris, because the slugs and snails like the iris more than the zinnias. The iris are finished blooming by the time the slugs are at their peak, and the zinnias add some interest to a corner that would be just plain shredded iris foliage.

very interesting mc.... slugs never touch my iris. I've had several people on this forum tell me that slugs won't eat green peppers, but they LOVE mine, their favorite thing in my garden, more than hostas or anything.

I guess different slugs have different preferences!
