Our walnut tree looks fine, we haven't started getting nuts yet.
But...a few of our oak trees don't look very good. The leaves didn't get very big this year. I'm hoping it has to do with the weather. We planted lots of trees 20+ years ago when we moved into the country. Now instead of mowing in the sun, we mow less and more of it is shaded. The house is much cooler in the summers too, which means smaller electric bills. yeah!!!
