White pine (Pinus strobus)




Propagation Method

Seed collection: Eastern white pine fruit is a large elongated cone. Harvest the fruit in the fall as the scales in the cone begin to open, but before the small winged seeds have been shed. The fruit can be allowed to dry, where it will open the scales and shed the seeds. For small quantity of seeds, the cone scales can be pulled apart to retrieve the seeds. They can be stored dry for long periods in air tight containers in the refrigerator.

Seed dormancy: Eastern white pine has physiological dormancy.

Seed germination: Stratify seeds using moist chilling for 60 days to satisfy physiological dormancy. Following stratification, sow seeds in a nursery container to produce a seedling or sow them in a plastic container in the classroom to observe germination.
