let me suggest.. that any tree that reseeds itself.. in number ... in your small yard .... is not a tree you want to be encouraging.. and moving around your yard ..

upon that logic.. it really doesnt matter what it is ... lol

besides.. you will probably be finding more of them all over the yard.. if you start looking close ..

i dont recognize it offhand ... my first thought was mulberry ... ruled out elm ..... wondered about hazelnut ... lol .. that ought to cover the bases... lol

ken

Maybe mulberry. Can you show a side view with stems?

Mulberry was my thought as well, the neighbors have one in their back yard. Thanks for your help, guess I will pull them out lol

I found another (what appears to be) mulberry tree in between my grape vine, which is at least 6 feet tall. They must be quite fast growers because i dont recall seeing it there last spring.
