How to Identify the Species

Leaves: four-sided stiff needles with dull pointed tip that’s green to blue-green in color. 1

Branches: the bark is smooth and thin with light grey coloration when young, with age it becomes darker and scaly. the twigs are hairless when mature and with rounded leaf cushions and open grooves. 1

Seeds: mature seed cones are slender cylinders with blunt tips and no stakes. Typically the length of the cone is 3-6 cm and the scales are brown, thin, tough, with rounded smooth outer margins. 1

What to Look For

Four-sided needles (square)

Grey bark

Blunt ended slender cylindrical brown seed cones

Indigenous Context

– The Cree peoples boiled its boughs, large branches, to purify indoor air and clean surfaces. 6

– The Red River Metis would make tea or build a steam bath from the needles of the white spruce to reduce congestion, flu symptoms, and reduce mucus buildup. 12

– Metis fiddlers used the gum of the White Spruce to rosin their bows. 13

Interesting or unique facts about this species

– The white spruce is Manitoba’s provincial tree. 14

– Some White spruce can live for more than 250 years 15

– White spruce also helps stabilize soils and protect watersheds! 15

STRUCTURE

Height at Maturity

15-25 meters 16

Canopy Spread

3-6 meters 9

OTHER INFORMATION

Soil Type

Moist loam or alluvium, although it’s tolerant of many soil types. Soil should be well draining and have a pH of 6.8-7.2. 17

Sun Conditions

Sunny, 6 hours or more of direct sun. 18

Watering

During germination the soil must be kept moist but not water logged. 19 Once planted outside, young white spruce trees require watering once a week under normal conditions and if very dry or hot then watering twice a week is appropriate. Watering should be plentiful and done in the morning to give the foliage a chance to dry and prevent fungus or disease. 20

Seed Collection

The seeds appear in May and should be collected around August to mid-September. 21 Collect once cones turn brown and the scales are not fully open, a cut test is recommended when collecting cones to check the maturity of the cone, cut the cone in half and there should be 10-14 dark brown mature seeds.22The cones must be collected in a container that has a good amount of air flow like a burlap sack, the seeds are then extracted by air drying the cones and tumbling them. 23If the seeds are intended to be stored, freezing in a sealed container is effective. 22

Growing White Spruce from seed

There are two protocols which can be followed one which involved seed chilling and the other does not. The first strategy is to chill the seeds at 3-5℃ for 21 days on a moist paper towel in a sealed transparent container, then sow into appropriate soil 22and allow for germination. Another strategy is soaking the seeds in water at room temperature for 24hrs and then sowing the seeds 1/8 inches deep into growing medium then water the pot gently and mulch if planting outdoor. 19 Germination of white spruce takes 3-4 weeks 23 with a recommended temperature of 15-20°C, with old seeds possibly benefiting from germination at the lower end of the range.24
