Canadian hemlock

Water the Canadian Hemlock regularly, at least once a week, with 1-2 inches of water. The amount of water can vary depending on the temperature and the environment, and may need to be adjusted accordingly. Make sure to water deeply and evenly so the entire root zone is saturated. If the soil feels dry, it's likely time to water. It's better to water deeply and less often than shallow and often.

Canadian hemlock (Tsuga canadensis) requires direct sunlight for a minimum of 4 hours each day. This is best achieved when the sun is overhead or close to it, with maximal light reaching the plant no later than midday. This species of tree does best in partial shade during the hottest hours of the day, and will also do well when located in the shade of taller trees providing there is a break in the sunlight at some point during the day. Canadian hemlock is a very hardy species of tree, however, and will survive in a wide range of sunlight conditions.

It's best to prune Canadian hemlock just after it has finished flowering in the spring and before new growth starts. This will help promote dense branching and a more uniform shape. For young hemlocks, you should wait until the tree is at least 5 years old to begin pruning. When pruning, it's important to avoid removing too many branches or cutting too deeply into the bark of the tree. Good pruning practices involve only taking off the tips of branches when needed to maintain the tree's overall shape. Don't be afraid to remove dead or diseased branches. Canadian hemlocks should be pruned lightly each year, if needed.
