White Spruce Tree Seeds (Conifer) 6790

This native tree of Canada grows in a wide range of conditions and soil types and can be found from southern Ontario all the way to the tree line in the Arctic. Trees in the wild can reach 25 m (80′) or more and live for hundreds of years. In the landscape they generally grow to 15-20 m (50-66′) high. White spruce is quite popular for windbreaks and for use in the Christmas tree trade. The wood is used for lumber and in pulp and paper production. Like many evergreens, it provides food and shelter for many birds and mammals.

How to Grow

Stratification of tree seed occurs naturally outdoors through the winter. Sowing tree seeds outdoors in the fall takes advantage of this natural effect. To stratify indoors, mix the seed with a moistened, sterile, peat based growing medium in a container, wrap in a ventilated bag, and place it in a refrigerator for 12 to 20 weeks. In the spring plant the seed in a sheltered spot outside to grow into seedlings. Transplant to permanent site when well rooted.

Norway Spruce Tree Seeds

The Norway Spruce tree can reach heights of 40 to 60 feet. The Norway Spruce is one of the fastest growing of the Spruce Trees. Commonly used as a wind break or shelter.

Soil Type: Prefers moderately moist, sandy, acid, well-drained soils.

Zones: 3 to 7

Germination Range: 70-90%

Stratification Requirement: None required.

Indoor Planting: If your seeds require stratification or scarification – do the recommended pretreatment before planting indoors. Planting Instructions: Fill a container with seed starting mix to about ½ inch from the top. Place your seeds 1 inch to 1 ½ inches below the soil surface. Gently water your seeds to keep moist, not soaking wet. Heat & humidity is critical for germination. Germination may occur in 1 week or as long as 3 months (depending on the species). Place the seed container on a heat mat under growing light(s). Keep your growing lights on 14 hours per day. Keep your heat mat on 24 hours per day. Once your seeds germinate, move each seed into its own container under the growing lights and on the heat mat. Keep your seedlings indoors for 2-3 months before transplanting outdoors in the spring (May to June).

Outdoor Planting: If your seeds do not require stratification: the best time to plant tree and shrub seeds outdoors is after the last frost in your area (spring). In the Northern states – the best time to plant seeds outdoors is from May to June. If your seeds require pretreatment: you should plant your seeds outdoors before the ground freezes in your area (late September to early November). Your seeds will naturally stratify during the cold winter. Germination usually occurs in May or during the spring season.
