Is my tree in danger
I just noticed my (white pine?) has all this white linty stuff all over it. I have never noticed it before and is my favorite tree. Is my tree in danger? I dont know and have been unable to learn what it is and what caused it. Any help would be greatly appreciated. Thank you.
Your tree is a hemlock and white stuff is the egg masses of an insect called the Hemlock Woolly Adelgid. When the eggs hatch, the insect will be in the crawler stage, seeking out a feeding site a little bit away from the egg sacs. They will then anchor in to feed with a piercing/sucking mouthpart, taking nutrients from the tree.
Watch closely for crawlers to hatch out, then treat with a horticultural oil when the temperatures are below 85 degree F, so as to not burn the tree. An alternative treatment is to use a soil drench insecticide that contains the active ingredient Imidacloprid.
Wow, thank you for your time. This should help greatly.
