I had an elm that died in my yard. I'm afraid for my other 3 elms. They didn't drop seeds nor did my Sun Rise maple. Should I be concerned? I have treated the trees with a Bayer product.

I would certainly talk to your local County Extension Office about the loss of an Elm Tree.
Many areas of the country are effected by the Dutch Elm disease, and if this disease is the cause they will want to be informed.
Here is a link to locate your nearest office.
The Maple Tree will most likely drop the seeds as soon as they mature and dry.
