Actually we know we are not going to truly remediate the damage... that's just what the original thread was called. You may recall this was 45" Quercus alba damaged by trenching Feb 2000, estimated 89% root loss. I updated you a while back:

"The Spring 2002 update on tree health is that the tree has leafed out within a few % of the crown that survived into Fall 2001, i.e. most of what was grren and the end of last Summer set buds that survived the Winter. Foliage size, quality and color are good and actually ahead of other undamaged white oaks in the area. Yes we are quite surprised about that. Tensiometers re-installed and borer treatment scheduled. Team re-evaluation scheduled for mi-late June when leaf expansion should be complete."

Team reinspection completed this week. Foliage size and colr quite comparable to 2000 and 2001 and other Q.A. in the area. A small amount of dieback between Fall 2001 and now... twings that had set bud but did not leaf out. We judged by comparing curent to Fall 2001 photos. A "flagged" twig here and there in crown... no more than 10. We were able to reach a couple and found exit holes of 2 lined chesnut borer and oak twig pruner. But no evidence of infestation in material larger than += 1". Some flushing of additional growth within crown... not new epicormic but on existing small branches. Patholgist found no Armillaria myceliun on the trunk or butresses below the soil line. A few rhizomorhps whic were observed as pre-existing prior to 2000 damage. Phytopthera test pending. Root growth core set at edge of damaged area 6/01 had quite a bit of new root growth in it. Same root growth found near large severerd buttress roots. No extensive dieback of cambium above the root cuts.

2001 pattern was that discoloration of some upper crown foliage became maybe sort of perceptible end of July, definitely visible by end of August and identifiable as dieback without bud set by October. So we know have to look for a pattern in the rest of 2002.
