Pruning them seems to increase their cold susceptibility. Since I stopped pruning them they barely have any dieback now.

This is in contrast with most other species, (i.e. all 28 cherries look good). We have some difficult rocky serpentine clay soil, but I was told by a neighbor cherries seem to like it here, and alas they do. I would not have thought mulberries would be the thing to struggle given their supposed wide-ranging soil tolerances, but they’ve done the worst among the 600+ trees of dozens of species that I’ve planted so far here.

So maybe the key is not to cut the branches after Augest?
Cutting back the dead wood yesterday, I noticed that one tree has a lot of orange dots (mould or fungus?) on the dead branches. But it's not on the other trees.
I have heard about several places in the USA where Mulberries are pretty much considered a pest. Alas, that is not true of the Pacific Northwest, where both I, r ranson, and I think Jocelyn might describe her location as PNW as well.
I can shave these stumps bare repeatedly, but they just won't die.
