Botanical namePicea × lutzii
Lutz spruce (Picea × lutzii) is a natural hybrid of Picea glauca and Picea sitchensis belonging to the Pinaceae family. Native to North America, it has a pyramidal coniferous shape and typically grows 20 to 40 m tall, with a spread of approximately 6 to 10 m. Its foliage is evergreen.
Plant it in full sun in cool to moist, acidic, well-drained soil. Medium to high humidity and good drainage promote consistent rooting. Its growth is moderate. Final dimensions depend on climate, soil, and available space.
This species is suitable for windbreaks, large plots, reforestation, and conifer collections. Cones and branches provide food and shelter for wildlife. When planting, allow sufficient space for a large tree and protect young plants from drying winds and mechanical damage.

Growing method
Sow in a fine, clean, and well-drained substrate. As specific dormancy requirements have not been provided by Gaiand, check the batch protocol before sowing. Maintain consistent moisture without waterlogging, place under bright light, and carefully transplant after vigorous seedlings appear. Gradually acclimate young trees before final installation. Choose a sunny location with cool to moist, acidic, and well-drained soil. Allow space for a mature height of 20 to 40 m and a spread of 6 to 10 m. Water during the first few seasons, then adjust watering based on drainage and rainfall.
Soil and care
The right care,at the right time.
Soil pH
Acid to neutral depending on the species
Care level
Moderated during setup
Watering
Maintain medium to high humidity during establishment. Water deeply when the soil begins to dry, then space out watering rather than watering lightly every day. Avoid standing water and adjust watering to rain, drainage, and temperature.
Soil type
Lutz spruce prefers cool to moist, acidic, well-drained soil. Maintain drainage, avoid compaction, and keep the root collar at ground level. A thin organic mulch helps stabilize moisture without touching the trunk directly.
Fertilization
Only fertilize if a soil analysis reveals a deficiency; avoid excessive nitrogen.
Moisture
Medium to high
Container growing
