Growing Mountain Hemlock

Mountain Hemlock is generally low-maintenance and becomes drought-tolerant once established. It prefers cool, moist summers and long, cold winters. It does not perform well in extreme heat, humidity, pollution, or heavy clay soils.

In warmer climates, choose a shaded location with only a few hours of morning sun. Keep the soil consistently moist while the roots establish. Water deeply, allowing the top layer of soil to dry between waterings to help prevent root rot.

Native Range

Mountain Hemlock is native to southeastern Alaska and the Pacific Coast, extending through British Columbia, Washington, Oregon, and Northern California. Inland populations occur in Idaho and Montana. It grows at sea level in the far north and at higher elevations farther south, including the Cascades, Sierra Nevada, Rockies, and Klamath Mountains.

Landscape and Bonsai Uses

Its graceful pyramidal shape makes Mountain Hemlock an attractive landscape specimen. Flexible trunks and branches help it withstand heavy snow loads, and its growth habit also makes it an interesting bonsai candidate.

Fertilizing and Pruning

• Heavy fertilization is not necessary.

• A light application of balanced, slow-release fertilizer in early spring can be beneficial.

• Pruning is generally minimal.

• If needed, prune in late winter or early spring.

• Avoid pruning old wood. Mountain Hemlock does not back-bud.

Soil Recommendations

Mountain Hemlock needs very well-draining soil, especially when grown in containers. We recommend our Dryland Conifer Potting Soil Mix.
