Conifers

Weeping White Spruce

Picea glauca 'Pendula'

Weeping white spruce combines an upward-reaching leader with steeply hanging branches and blue-green needles. Its narrow evergreen silhouette makes a striking vertical specimen, but final size depends on the plant and its training. Allow roughly 12–40 feet of height and 5–8 feet of spread rather than assuming a permanently small conifer. Choose a cooler, sunny position with good air movement and moist, freely drained soil. Southwest Washington's dry summers still require attention to establishment watering. Avoid crowded corners, reflected pavement heat, and repeated overhead irrigation. Check leader supports as the tree develops and keep pruning conservative.

The right plant, the right place

Make room for something good.

The upright stem and hanging branches provide height in a conifer bed without a broad canopy. Allow space around the narrow outline so the branches can hang freely.

Where to plant

Allow roughly 12–40 feet of height and 5–8 feet of spread. The strength and training of the main stem affect the final shape, so inspect the individual plant before siting.

Through the seasons

Blue-green needles remain year-round, with small cones possible as the tree develops.

Southwest Washington gardens

Give it a good start.

A cooler site with good air circulation suits this spruce best. Avoid hot enclosed corners, salt spray, and crowded planting, and provide water during summer establishment.

Soil, drainage & water

Use moist, well-drained soil and avoid leaving roots saturated. Direct irrigation toward the soil rather than repeatedly wetting the needles, particularly where foliage disease has been a problem.

A little care goes a long way

Growing well, season after season.

Maintain support for the main stem if an upright form is desired and check it as the tree grows. Remove dead branches and keep other pruning limited.

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.

Needle cast

Needles may develop yellow mottling, become brown or purplish, and fall. Rows of small black spots can appear.

Help your plant thrive

Remove diseased fallen needles, reduce overhead irrigation, and prevent crowding. Have recurring needle loss identified before treatment.

Spruce aphids

Yellow patches, browning, or needle drop can follow feeding in winter or early spring.

Help your plant thrive

Inspect needles during the cooler months. A water spray can remove insects from accessible small trees, while preserving predators helps limit colonies.
