|I'd like to plant the Canadian hemlock as a screen in an area that is approximately 12-15' wide by 150'. I'm not sure if the tree will grow too big for the space. Is is possible to keep the Canadian Hemlock to a size of about 7-8' in height and 10' spreading habit? I love this tree and need an evergreen that is more natural than the techny arborvitae.|
Thanks for your time
|The normal height for a Canadian hemlock is 40-70' so trying to keep it 7-8' in height will be very difficult! These trees do take well to shearing and are often used as a dense screening hedges, but it takes regular pruning to keep them as small as you want them to remain. When they're sheared, they're usually kept at about 20'. I think you'd have better success with Tsuga canadensis 'Pendula' (Sargent weeping hemlock) in the site you describe. This hemlock grows to 5' tall and about 15' wide.|
Best wishes with your landscape!
