Sargent's weeping hemlock

Tsuga canadensis 'Pendula'

Weeping Canadian hemlock layers fine dark green needles over drooping, overlapping branches. It may remain a low mound or develop a taller weeping outline with support, so choose the individual plant's shape carefully. A common garden form reaches about 4–5 feet tall and 8–10 feet wide, but training can change those dimensions considerably. It suits a shaded conifer bed or sheltered woodland-style specimen position. Summer dryness is a key concern in Southwest Washington: provide regular water during prolonged dry spells, even in shade. Moderately moist, well-drained soil, mulch, and protection from hot winds help preserve its soft evergreen texture.

The right plant, the right place

Make room for something good.

In a shaded conifer bed or woodland garden, this hemlock can form a broad evergreen mound. Training changes the outline, producing a taller specimen with weeping branches.

Where to plant

Check the individual plant's shape before choosing its position. Common forms spread 8–10 feet, and training can greatly change height, so allow room for the trailing branches.

Through the seasons

Fine dark green needles remain year-round, with pale bands underneath. Small tan cones may appear on older plants.

Southwest Washington gardens

Give it a good start.

Summer drought and drying wind are important concerns in Northwest gardens. Partial shade provides protection, but soil can still dry beneath taller trees and needs checking.

Soil, drainage & water

Use moderately moist, well-drained soil, preferably with some acidity. Mulch the roots and water regularly during prolonged dry spells, especially while the plant establishes.

A little care goes a long way

Growing well, season after season.

Guide the shape deliberately if training is needed and keep pruning selective. Check how trailing branches are developing, and continue watering in dry periods rather than assuming shade provides enough moisture.

Know what to look for

Common growing concerns.

Symptoms can have more than one cause. These notes are a starting point for observing your plant and improving its growing conditions.

Dry-weather decline

Needles may brown and branches thin after drought, hot exposure, or drying wind.

Help your plant thrive

Monitor soil moisture in shaded positions too. Water during extended dry spells and protect the roots with mulch.

Hemlock adelgid or scale

White woolly tufts or scale insects can occur on needles and twigs. Heavy feeding may accompany declining growth.

Help your plant thrive

Inspect needle undersides and young shoots. Identify the insect before choosing treatment and maintain suitable moisture to reduce stress.
