Canadian hemlock

Tsuga canadensis 'Jervis'

Also Known As - eastern hemlock
The Canadian Hemlock (Tsuga Canadensis 'Jervis') is an evergreen conifer native to Canada and the Northeastern United States. It is a popular and attractive ornamental tree, with dark-green aromatic needles and a drooping crown of sweeping branches. It grows to a height of over 50 feet, with long upcurved branches that end in an irregular pyramidal shape. Its bark is greyish-brown and deeply furrowed, and its twigs are slender and yellowish-green in color. The Canadian Hemlock is hardy to cold climates and tolerant of wet conditions, making it an excellent choice for northerly landscaping.

watering

Canadian hemlock prefers moist, well-draining soil for optimal growth. Water the plant thoroughly, saturating the soil to ensure that it is receiving enough hydration. During periods of drought, it is important to water once weekly. In periods of moderate moisture, it is important to water every other week. During periods of heavy rainfall, it is important to ensure the soil is not saturated. If puddles form, the soil is too wet and air pockets may form. In this case a well-draining soil mix with sand is recommended to combat water-logging.

sunlight

Canadian hemlock (Tsuga canadensis 'Jervis') requires full sun to partial shade and thrives best in a location that receives at least 4 hours of direct sunlight each day. This species of hemlock is an evergreen conifer tree that grows best in moist, well-drained soil, and it is hardy in the USDA plant hardiness zones of 3-7. During the summer months, it is important for Canadian hemlock to receive consistent sunlight in order to grow and flourish, but too much sunlight can cause the needles and foliage to burn. For optimal growth, the tree should receive direct sunlight in the early morning or afternoon, and partial shade during the hottest time of the day (around midday).

pruning

Canadian hemlock (Tsuga canadensis 'Jervis') should be pruned once annually. The amount of pruning depends on the size and desired shape of the tree. Generally, it is best to prune out the tallest or widest branches and thin out the dense clusters of branches to increase sunlight access. This should be done in the early spring, before the new growth begins. Always take out branches damaged or infected with pests or diseases. Avoid pruning too much and removing multiple branches from the same area.
