My husband is blaming it on the big leaves of the walnut choking
the base of the hedge! He may be partly right. I have room to try a variety
of things but also sometimes have sheep next door so I have to be a bit
careful.

I agree with him! I have pruned our walnut so that the first 8 feet
of its trunk is bare, and the leaves start at 10 feet. It was very
noticeable how much the lawn perked up when I first started that
process.
