About White spruce
Picea glauca, commonly known as white spruce, is a slow-growing evergreen conifer native to North America. It is characterized by its conical shape and short, blue-green needle-like foliage. It is ideal as an ornamental tree in large gardens, parks, and as a Christmas tree, providing a majestic presence.
Native range
North America, specifically Canada and the northern United States
Care tips
It requires full sun for optimal development, although it tolerates some partial shade. It prefers moist, well-drained, and slightly acidic soils, avoiding waterlogging. Watering should be regular during the first few years and in dry periods, but once established, it is quite drought-tolerant. A common mistake is planting it in heavy, poorly drained soils, which can lead to root rot.
