Tree advice - Z4, clay soil
 

I'm in zone 4 (se minnesota) and want to plant a couple new trees out
front. We just removed a pin oak that has been strugling with the very
non-acidic clay soil for several years and I'd like something that will
tolerate the soil.

Lindens are growing along the street succesfully. In the back I have an
ash and a maple and two black pines (the soil out back seems to be a
little better than the front).

In addition to the lindens along the street, the neighbors have birches,
ashes and a sickly maple.

I was hoping to get something that would grow tall enough to shade the
front of the house (2 story). Something different from the neighbors
would also be nice.

Any suggestions?

I'm quite a bit south of you, but face the same pH issues. Maples and
pines are pretty much out (here we can grow bigtooth maple, but it's a
native and I doubt it is hardy in z4).

Ash tend to grow fast, die young. I would avoid them.

Most oaks can take the high pH, though you've obviously noted an
exception. We like live oaks, shumards, bur oak, and chinquapin, but
I don't know which are most suited to your climate (maybe none).

Elms also can make it in alkaline soil. American elms are available
now that are resistant to Dutch Elm Disease. Other elms also might do
well up there.

For smaller trees, Chinese pistache is recommended locally. Again,
check for hardiness.

Sorry not to be more helpful. You might do best to contact your local
county agricultural extension office.
