What is wrong with my Black Walnut tree?
Our tree normally drops thousands of walnuts every year, which is a pain cleaning up but it is so big it shades the entire front half of our house. This year we've only had a few walnuts and then mid July the tree started dropping leaves. The lowest branches are getting quite bare. The tree is at least 50 years old. Probably quite a bit older. I would hate to lose it.

Walnut trees produce nuts in cycles. Heavy for a couple of years and lighter for two or three. Leaf loss could be from stress such as dry hot weather. Wal nut trees don't start their best nut production until they are 20-30 years old and live to be 200 years or more. You have to think about what is different about this year. Was it hotter, dryer, colder winter? Did something in the immidate area change? They don't like to be crowded. Just some thoughts.

You don't say where you are, but I hope your tree is not suffering from "Thousand Canker Disease", which has recently been identified in the eastern U.S. It takes years to really manifest, but there is no treatment.
The best thing to do is to get an arborist out there to look at the tree in person. All we can do here is speculate. And speculate very broadly, as lots of different things can cause defoliation in a tree, or poor fruit production.
