| Tsuga caroliniana Carolina hemlockCulture: The Carolina hemlock prefers a well-drained, moist, partially shaded site, but although from a warmer climate than Tsuga canadensis, this species will still not tolerate drought or even hot summer temperatures if the soil is too dry. According to Dirr, this species tolerates urban conditions better than Tsuga canadensis. This species is susceptible to the adelgid aphid that plagues the Canadian hemlock in the eastern U.S. In the Midwest, this insect has not been a problem and this species has few other disease problems, although hemlock scale may occur. Usage: Because of its dark green color and spire-like habit, this species is useful as a specimen, screen, or in a mass planting. It will tolerate shearing. |
