Live in New England, outside of Boston
Have a question about Woolly Adelgid bugs and Hemlocks:
Have a massive Hemlock in backyard that, for the first time I think, is
several "leaves" on various branches which have turned an orange color.
Looking at them closely, I can find no evidence of white spots, white sacks,
on either the tops or bottoms.
Can anyone explain what might be happening ?
Water deficiency, time of year, etc. ?
Think it might be a Woolly Adelgid Problem, even without my
being able to see any evidence of ?
Really appreciate the help.
