Maples with Severe Bark Loss: Likely Fatal

10 Maples with 5-ft Bark Strips: Poor Prognosis

If bark is gone/loose around most of the trunk circumference, the cambium is dead. Tree cannot transport water/nutrients.

If any trees still have solid bark + green foliage: fertilize 10-10-10 at 1 lb/inch trunk diameter. Avoid weed-and-feed.
If bark loss is near-complete: remove the tree. It will not recover.

Severe winter likely caused frost cracks on thin-barked maples. Sunscald + rapid freeze-thaw = bark separation.
