Canadian hemlock

Tsuga canadensis 'Curley'

Also Known As - eastern hemlock
Canadian hemlock (Tsuga canadensis 'Curley') is an evergreen coniferous tree native to North America. It has attractive blue-green needles that curl upward along the branch, giving the tree a unique and striking silhouette. Its dense foliage provides excellent privacy and wind protection and its silver-gray bark adds texture to the landscape. This fast-growing species is resistant to drought, pests, and cold winters, and it makes an excellent choice for hedges, borders, screens, and mass plantings. It requires little maintenance and thrives in most soil conditions. Canadian hemlock 'Curley' is a smart choice for creating a beautiful and eco-friendly garden.

watering

Canadian Hemlock should be watered regularly. Its best to water thoroughly and deeply, allowing the water to reach the roots. This can be done by soaking the soil around the plant 1-2 times a week. During the summer months, water more frequently during extended dry spells. During the winter months, water less frequently, only providing water when the soil is dry. Canadian Hemlock prefers moderate to regular irrigation, so it should not be left in standing water or entirely dry for too long. Do not over-water as this can cause root rot or other water related issues.

sunlight

Canadian hemlock (Tsuga canadensis 'Curley') prefers full sun to partial shade, with 4 to 6 hours of direct sunlight each day. The amount of sunlight the plant receives depends greatly on geographic location and time of year. In northern parts of Canada, like Ontario and Quebec, Canadian hemlock will receive the most sunlight in the summer months, from June to September. During this time, the trees should receive at least 4 hours of direct sunlight per day (from 10 am to 2 pm being the best). In southern parts of Canada, like British Columbia, Canadian hemlock will usually receive the most sunlight in the spring months, from March to May. During spring, the trees should receive at least 4 hours of direct sunlight per day (from sunrise to 10 am being the best).

pruning

Pruning Canadian hemlock (Tsuga canadensis 'Curley') should be done in the late winter or early spring. For artistic pruning, dead or damaged branches should be removed as needed. An overall light pruning may also be carried out to remove suckers, remove any interfering branches, shape the plant and to thin out the density of the foliage. Pruning should be done gradually, removing no more than a third of the crown in any given season, and should be done with care to minimize injury to the plant. Pruning of the top of the plant should be avoided in order to keep its natural shape. An annual light pruning is usually adequate to keep Canadian hemlock looking healthy and attractive.
