Seed Source: Siberian pine collection near Indian Head Saskatchewan.
Height and Spread: 20m x 8m.
Overview: Siberian pines are native to Siberia. The 'Baikal' seed strain originates from a collection made near Lake Baikal in Siberia in 1985. The collection was planted in a seed block near Indian Head, Saskatchewan. They are drought tolerant and our seeds are well adapted to northern temperate regions. The 'Baikal' seed strain has grown very well in southern Saskatchewan. It is ideally adapted for planting in non-boreal regions. Siberian pine grows well in heavy clay soils. Typically it has steady though not fast growth and is very tolerant of severe winter cold, hardy down to at least –60 °C, and also of wind exposure. Unlike other pines Siberian pine drop their needles mid-summer so don't be alarmed if your tree begins to turn shades of yellow from old needles dying in the summer. The needle drop is over after a few weeks
Seeds: Yellow-brown and nut-like, 10-12 mm long.
Average number of seeds/packet: 60
SEED TREATMENT / SOWING
Stratification: Soak in water for 24 hours then warm stratify at 20°C for 60 days in moist sand followed by 120 days at 5°C.
Ideal sowing time: Sow stratified seed outdoors in May or non-stratified seed in late August.
Sowing instructions: Outdoors - sow 1.0 cm deep, 50 seeds/meter; Greenhouse - sow 3 seeds per cell.
Growing conditions: Spring sowing of stratified seed is preferred over fall sowing of non-treated seeds. Alternatively, sow seed indoors then move outdoors in a shaded area during the summer. Sow stratified seeds in individual pots with well-drained potting soil. Push each seed just beneath the soil surface, making sure that it’s in a vertical position with the pointy end facing downward. Place the pots in a sunny window and water thoroughly. Keep the seeds moist and wait, as germination can take a few weeks. Plant seedlings into their permanent position within 2 years after sprouting, and mulch heavily before winter.
'Baikal' Siberian pine seeds are tasty and nutritious, they have been harvested and eaten by people for generations. In addition to its abundant crops of tasty nuts, Siberian pine is also valued for its attractive dark green foliage and dense, pyramidal shape. Its slow growth rate makes it a good tree for small gardens.
