Picea glauca (Moench) Voss., the White Spruce, [4] is a species of spruce native to the northern temperate and boreal forests in Canada and United States, North America.. Picea glauca is native from central Alaska all through the east, across western and southern/central Canada to the Avalon Peninsula in Newfoundland, Quebec, Ontario and south to Montana, North Dakota, Minnesota, Wisconsin ...
Picea engelmannii is a medium-sized to large evergreen tree growing to 25–40 metres (82–131 feet) tall, exceptionally to 65 m (213 ft) tall, and with a trunk diameter of up to 1.5 m (4 ft 11 in). The reddish bark is thin and scaly, [ 6 ] flaking off in small circular plates 5–10 centimetres (2–4 in) across.
With a view to reducing the time needed to produce planting stock, experiments were carried out with white spruce and three other coniferous species from Wisconsin seed in the longer, frost-free growing season in Florida, 125 vs. 265 days in central Wisconsin and northern Florida, respectively.

Mullin and Forcier (1976) [23] and Mullin and Reffle (1980) [24] examined the effects of spring-lifting date and planting date on several species, including 3+0 white spruce after frozen storage, with fresh-lifted controls planted on each planting date for comparison. In all plantings, the earliest (2 May) lifting gave highest average second ...

Containerized white spruce stock is now the norm. Most containers are tube-like; both diameter and volume affect white spruce growth (Hocking and Mitchell 1975, Carlson and Endean 1976). [ 6 ] [ 7 ] White spruce grown in a container having a 1:1 height:diameter produced significantly greater dry weight than those in containers of 3:1 and 6:1 ...
In west-central Alberta, he felled, measured, and weighed 60 white spruce, graphed (a) slash weight per merchantable unit volume against diameter at breast height (dbh), and (b) weight of fine slash (<1.27 cm) also against dbh, and produced a table of slash weight and size distribution on one acre of a hypothetical stand of white spruce.
