Planting & Growing
Mountain Hemlock will grow to be about 90 feet tall at maturity, with a spread of 40 feet. It has a low canopy with a typical clearance of 3 feet from the ground, and should not be planted underneath power lines. It grows at a medium rate, and under ideal conditions can be expected to live for 70 years or more.
This tree performs well in both full sun and full shade. It does best in average to evenly moist conditions, but will not tolerate standing water. It is particular about its soil conditions, with a strong preference for rich, acidic soils. It is quite intolerant of urban pollution, therefore inner city or urban streetside plantings are best avoided, and will benefit from being planted in a relatively sheltered location. Consider applying a thick mulch around the root zone in winter to protect it in exposed locations or colder microclimates. This species is native to parts of North America.
