Sick Tree

Asked March 31, 2016, 9:42 AM EDT

Hi - I recently bought a house with a large evergreen variety that is not looking very healthy. I was wondering if there are any options for helping me identify what's wrong and how it can be saved. Thanks!

It looks like a Eastern hemlock tree and that usually means it has Hemlock Woody Adelgid, an insect pest that is wiping out native hemlocks across the eastern US. Look at this VCE publication to be sure and to determine if control measures are warranted.

For control recommendations use this Pest Management Guide: https://pubs.ext.vt.edu/456/456-018/456-018-16-Home-grounds-and-animals.pdf


As an aid to others, let me add that adelgid is easily recognized by a fluffy white mass along the stem. To make one's life worst, even in the unlikely event you kill them, they look exactly the same. So despite how gorgeous before infected, I would never plant another one. Good luck from a gardener in MD. g.l.
