I live in Granville, Licking County, and have several healthy, mature white pine trees that probably were planted around 1962. Needles on one of the trees began turning brown, affecting the whole tree, apparently branch by branch, within a matter of weeks. The neighboring trees seem unaffected.
There is evidence of insect damage (little piles of “sawdust”) near the base of the affected tree on one the neighbor’s side, extending up the trunk only to eye level.
A volunteer also had been working on scraping, bleaching, and painting siding on the side of my house closest to these trees, and it is possible that household bleach sprayed on the siding or spilled on the soil might have affected the tree roots. Consistent with this hypothesis is that English ivy leaves on vines on the trunk also have died, although dicots at the base of the tree seem unaffected.
I attach a photo of the tree taken from a neighbor’s deck, and also some showing the “sawdust” and dead English ivy. No insects are visible. The bark is not loose.
Thank you for any insight,
Licking County Ohio
