Thanks Adair, you're totally right.  I should've looked at my notes I made from that thread. 

"You leave roots on 1/2 of the tree with soil on them, this is insurance that functioning roots are available to support the tree. However, since you have already pruned the bottom of the entire root pad, and cleaned up the roots around the edge of the pot, cleaned up the top of the entire root pad, them bare rooted 1/2 of the remaining roots, you only end up with 15-20% of the original roots still in soil. As wayne inferred, leaving roots sticking out of the edge of the non barerooted section helps to get the new root growth started despite the bad soil."

For some stupid reason, I had it in my head not to cut the root mass in half.  And on this tree, one side is VERY healthy...it's the side that the main nebari is on, and that dries out completely.  It's only the other side that never dries out. 

I did make one mistake on this pine though...I'm willing to admit lol, and that was I removed too many old needles last fall.  Not fatal, but a stupid mistake.

Looking at my records, I just realized that I had forgotten my Feb. overwintering anti fungal spray.  Now I'm once again having tip blight on a shimpaku, and this JBP.  Lost a key branch already.  Last yr. this kicked me in my ass, loosing sev. trees despite treatment.  I'm very angry with myself over forgetting the spray as I might've prevented this attack.  Oh well.  I sprayed them yest. with Bonide Fusion and Daconil.  Today I sprayed them with copper.

The bad soil conditions of this JBP exacerbates the problem.   I need to do that partial repot we discussed in another thread.  But I'm hesitant to do it with the fungal disease.  Should I wait till I'm sure I got the blight under control before the repot?

Thanks guys,
Chris

Edit:  I also sprayed all my evergreens.

I'd go ahead and do the partial repot.  Trees with healthy root systems can fight off the fungus problems.  It might be getting the fugus because it needs a repot.
