Perhaps a Black Walnut?

I have several of these growing in my landscaping. Here's one I pulled up. There are a few others still growing. I would like to transplant, if possible, but they have pretty deep tap roots.

 

Ash tree seedlings I believe.

Thanks.

 

Yep, an ash.

 

Poor Ash. Read up on EAB if you are tempted to keep it.

I love ash but are relegating them to tree lines in my lanscape.

 

Yes, I've read of the horrors of EAB. Southern Indiana is getting infiltrated now, it seems. :(
