Native Range: Native to Rocky Mountain region of Canada and United States.

Seed Source: Ponderosa pine shelterbelt near Indian Head Saskatchewan.

Overview: Ponderosa pines are large trees native to the Rocky Mountain region of North America. They are drought tolerant and our seeds are well adapted to northern temperate regions. 

Seeds: Dark brown, winged 6-7 mm long.


Stratification:Soak in cold running water for 48 hours then stratify for 30 days in moist sand at 5°C.

Ideal sowing time: Sow soaked seed outdoors in May.

Sowing instructions: Sow 1.0 cm deep,50 seeds/meter; Greenhouse - sow 3 seeds per cell.

Growing conditions: Ponderosa pine grows on a variety of soil types but does best on coarse-textured soils when available soil moisture is limited. It favours a pH of 6.0 to 7.0 and is intolerant of shade. Its ability to grow vigorous taproots is one reason for their good growth on dry severe sites and ability to firmly anchor into the soil.

Agroforestry Value

Ponderosa pine is an excellent choice as a tall tree component in shelterbelts and Ecobuffers, offering year-round protection and relatively rapid growth. It is suited for Eco-Buffers, wildlife planting (food, nesting, cover), and carbon sequestration.
