Tsuga canadensis, or Canadian hemlock, is native to eastern North American and thrives in well-drained locations. While somewhat adaptable to pH levels, it prefers acidic soil, and cool, moist but typically well-drained conditions. This slow-growing tree grows in light shade and sheltered sunny locations but will not typically thrive when planted in deep shade. Sunscorch and drought can cause significant damage, potentially killing the tree. Healthy trees can withstand the various diseases and pests that are known to impact this tree including leaf blight, cankers, blister and needle rusts, and sapwood rot. The invasive insect, hemlock wooly adelgid is threatening the future of this species in eastern Canada. There are treatment options for trees with light infestations, but untreated trees will typically succumb to this pest within a few years.
