Noteworthy CharacteristicsMost hemlocks are native to forests of Southeastern Asia and North America. They can tolerate a considerable amount of shade, particularly when young. 

CareGrow in moist, but well-drained (acidic to slightly alkaline) soil in full sun to full shade. Prune hedges in late summer or early fall. They are notably at risk of infestation by woolly adelgids, scale, and mites.

PropagationSow seed in a cold frame in spring; root semi-ripe cuttings in late summer or early fall.

ProblemsBotrytis (gray mold), rust, needle blights, butt rot, snow blight, weevils, mites, aphids, woolly adelgid, scale.
