MSU Extension (1 yr ago) tested my mature white oak tree and determined it had “environmental leaf scorch”. In August 2025, the leaves were 60% burnt out. I excavated the root flare that was buried 45 yrs ago during home construction. Your groups answer was “dig deeper”. I did that last July and within 4 weeks started seeing about 50 new leaves grow at top of canopy, but 2/3 of leaves were scorched by that point. Now in 2026, around May 1, I dug another 8” deeper (24-27” in total) to expose root flares. Weather in May has been hotter than normal, June even hotter. Tree canopy has been out for a month. Looking perfectly healthy. BUT, shooter leaves off of trunk, 10,15 and 30 ft up the trunk are already burning out. Why? A tiny handful of leaves at end of the lowest branch up 30 ft are starting to show early leaf scorch. See pics. We had 2 weeks with little rain, during which I watered the grass out to the drip line. In past 2 days lots of rain. QUESTIONS Did I excavate roots flares enough? What else can I do to minimize or eliminate environmental leaf scorch again this year. FYI- over past five years leaf scorch got progressively worse. See many pics. Thnx!
