I read a couple Extension papers on VW and looked at a few pictures of the streaking that is common in the wood. I will cut into it tomorrow and take a look. I am going to read up a bit more though, as I didnāt have much time earlier.
I am not oposed to spray at all. I try to minimize what I do, but once I see a need, then I make the effort to treat the problem. Part of my challenge is that my trees are still young and I donāt know what WILL be a problem. Rather than spraying a bunch of preventative stuff they maybe donāt need, I have been trying to monitor and spray when I do see an issue. I completely dropped the ball with this cherry though. I knew there was a problem but didnāt take the time to address it before I left. I never dreamed it would die! I didnāt think it was that serious. This year I am trying to take a more proactive approach and keep ahead of disease and pests, if possible. 
Looking back at my notes on spray treatments last year, it looks like the cherries got two rounds of Neem in March 21 and June 7. They got Permethrin, Captan, and Immunox on 7-30.

I donāt need the spot technically. I just wanted to have another cherry there, because it is the first tree in the row of cherries. So it will look weird to have a blank spot there! But I want the new Monty to have the best shot at survival, so I will pick out a new spot for him somewhere else. Thank you for your advice on ācompostingā the spot for a year.
