I found some American Elm trees lining the break line between my grandfathers yard and the woods, probably the only one on the entire block. I want to take them back to my house and plant them in my yard, possibly raise one or two in a pot. This one is too large to pot I may transfer it in a pickup truck, how far out should I dig? This one is small I potted, might make into a bonsai: This one is in a temporary pot: I did use a small handful of "biotone" in the soil and sprayed the leafs with "Seven" becuase there was some sort of mite and small brown spots. What can I do to prevent DED if I plant them in my yard, all I have is a beetle to keep away.
