Shumard yellow oak

[Tree Dude]

Is there a point where limestone is too much for shumard oaks to handle?
My tree was excellent the first year. After that year it has been going downhill. This is new home. Could that have messed up the soil? Flares are expose, no wet feet. The only 2 things I can think of are as follows:too rocky(limestone) or a southern/shumard oak hybrid, which does not look like it at all. Everything else in the yard is super. Been organic day one.
This fall, I might have to "fire" this tree if it does not fly,or grow, right .

Sounds like you may have a mix breed tree that has pin oak or northern red oak blood. Texas and shumard red oaks can grow in solid white rock, and do, all over the place.

Thank you. That was the only thing I could think of--pin oak or southern red oak breed (strangely, when I bought the tree, the tree was incorrectly name Southern Red oak with bot.name Quercus shumardii :roll:)
So,if I transplant it in the East Texas,would that be ok? Of course, to where and to whom is an issue.

I have two shumard oaks from two different sources. They are noticibly different. One has dark green leaves (significantly more leaves) and one has lighter green leaves. Both planted few months apart last fall.

How do I know right away that it isn't the correct "shumard" for limestone soil?

Unfortunately there is no way to know for sure. All the oaks cross breed significantly. All you can do is wait and see how the trees do.

I came across this info about finding out whether red oak is suited for alkaline or not. Maybe it might be helpful, who knows?
