Here in the Hudson Valley, z5, Tsuga canadensis seems totally hardy and
tough. They are favored as hedge plants, as they can be sheared and will
grow really thick. However, and this is a big however, they have been nearly
wiped out in the wild by wooly adelgid (I have the technical name somewhere,
but it is similar to mealy bugs on your house plants). We have managed to
keep our hedge and several large unpruned hemlocks by dint of spraying three
times a year with dormant oil spray, but heavy stands in the woods near us
are completely dead - all this has come about in less than ten years.
Also, but this may not be a problem elsewhere, our hedge has suffered from
road salt in recent years. Until five years ago we had no road services at
all, but five years ago the town started plowing and salting our road, and
the hedge now has brown dead patches at the points where puddles formed in
the road and splashed on the trees. It's been helpful to have the road
plowed, but the damage to the hedge is distressing.
Hemlocks are beautiful trees, and until these past few years I would have
thought they were practically indestructible. Even deer don't eat them.
