How to Propagate Mountain hemlock?
(Tsuga mertensiana)
Mountain hemlock, also known as Hemlock spruce, Patton Spruce, Western Hemlock
An evergreen conifer with a narrow conical shape, mountain hemlock is primarily propagated through cuttings. Successful propagation demands selecting healthy semi-hardwood cuttings during periods of active growth. These cuttings should be treated with rooting hormone to stimulate root production and then placed in a well-drained growing medium. Stable moisture levels and partial shade conditions are essential to ensure rooting. With its inherent resistance to cold, mountain hemlock can be a slow grower; patience is fundamental as cuttings take time to establish a robust root system.
