Texas Gardening: Part of my lawn is really green, 1 by konkreteblond

I'm posting this here because I just can't seem to find the right place for it. My trees have this same issue for the past 2 years, almost to the exact date, where they are yellowing and one side of the smaller tree (which will be on the right in the picture) doesn't grow well. We still have no idea what is wrong with it except that what we thought were Shumard Red Oaks are possibly a cross between Red Oaks and Pin Oaks that hate alkaline soil. I guess that half is a Pin Oak.

We've been putting iron out around both trees drip line hoping to help correct the problem. I'm not sure that it has since they've started turning yellow again but the grass around the trees is really green now. Does that mean the bermuda is liking the iron or does that just have something to do with the tree and roots in that area? Last year the lawn was much greener and thicker everywhere at this time but he had also put down some Scott's fertilizer. He did not winter fertilize and this spring put out an organic fertilizer instead.

My husband is wanting to put a little of the iron in other places but I said let's ask first.
