Hemlocks turning brown

mishman · 04-06-2015, 08:05 PM

There has been very noticeable die back of hemlocks since last fall. I think it is caused by an aphid. Very surprised at how quickly it has occurred in our area of Moultonborough Neck. Has anyone had any luck with insect sprays or ground treatment? Would appreciate any advice that can help protect these trees. Once a tree starts to turn brown near the top, is it a lost cause or can it still be saved with treatment?
