Hello Richard
The best time to prune walnut trees is when they are dormant. They can be pruned now in mid-summer. Do not prune in late summer or fall. Here is more detail

Be careful to not cut into the branch collar( see illustrations in second link). Use the “three cut method” on branches over 1.5 inches thick.( see third link for good illustration)
We recommend using a professional service if you can not safely stand on the ground and prune, or if limbs are large. Trained Professionals can be found here by zip code- treesaregood.org
