Canadian hemlock

Watering a Canadian hemlock depends on the climate. In a hot, dry climate—with temperatures ranging from 32°F to 95°F (0°C to 35°C)—it is best to water the plant deeply and regularly. Aim to provide about 1 to 1 1/2 inches of water per week, either through rainfall or through supplemental irrigation. If you’re concerned about over-watering, monitor the soil moisture levels. If it is dry 2-3 inches below the surface, it’s time to water. In cooler climates—with average temperatures between 20°F to 75°F (7°C to 24°C)—it’s best to only give the plant water once every 2 to 3 weeks, or when the soil is dry 1-2 inches below the surface.

Canadian hemlock (Tsuga canadensis 'Golden Splendor') requires full to partial sun. It is best suited for direct sun for at least 4-6 hours a day, although it can tolerate some light shade in the afternoon. In hotter climates, it may need some afternoon protection from extreme heat. It is an evergreen so it requires the full sun throughout the year, ensuring the needles remain vibrant and healthy.

The Canadian Hemlock is a fast growing conifer, and can benefit from regular pruning. In general, it should be pruned in early to mid-spring, before the tips break dormancy and the new growth begins. To maintain the shape of the plant, lightly prune off new growth as needed throughout the growing season. The Canadian Hemlock can be pruned to shape it and encourage bushier growth. However, it is best to avoid major pruning as it will cause the plant to lose its natural shape.
