I was appalled to read a book by Mr Garrett that describes the pin oak as non-viable in the DFW area. I didn't know it was a pin oak when I purchased it, relying on the seller to provide proper trees for the Park Glen area. I am hoping to get info expanding on what the problem is with the oak.
The tree is in its 5th year and has shown moderate grown so far. I have been concerned the last 3 years because the leaves show what I thought was chlorosis due to lack of iron. I treated the tree in the 3rd year with chelated iron spray and the leaves turned much greener. Last year and this year the iron treatment has had no effect on the tree. It resembles the pin oak foto shown in Mr Garrett's book, PLANTS OF THE METROPLEX. That foto and the closeup of the leaves are exactly what my tree looks like i.e. a yellowish cast with the dark green only around the leaf veins.
He doesn't mention exactly why he considers the tree non-viable. Does a healthy pin oak have the yellow cast and green veins or are his pictures a wordless depiction of what the problem is? If this tree is doomed I might as well cut my losses (a pun!) and try another tree. If so, perhaps someone can recommend the proper tree to provide shade in the front yard, of fast to moderate growth in full sun. The soil is clay, hard as a rock (almost) except when wetted.
I would appreciate your input. If I choose to buy a large tree can I plant it safely this time of year?

Just off the top of my head, I'd say the issues this type of tree has everything to do with soil type. I believe this one likes soil more on the sandy, acid side and what you have there is much more likely to be the alkalai clay side of things.
The full Sick Tree Treatment might be able to help it along, but ultimately it's not really well suited for where it is.
