Ginkgo biloba

Seeds Type

Orthodox, that is to say seeds with the capability to withstand desiccation and freezing temperatures (-20°C) and may therefore be conserved for years, if not decades.

For germination, you must...

1. allow FIVE MONTHS for seed treatment;
2. subject them to a scarification AND a warm stratification, THEN a cold stratification, before sowing (follow the steps below in order).

Scarification : Soak the seeds in water at room temperature for 24 hours.
Stratification (warm and cold) : Place the seeds in a bag (Ziploc Slider type) containing slightly premoistened peat moss. Seeds should be surrounded by the latter. Close the bag and place it at room temperature for about two months, then in cool storage (between 1°C and 5°C) for approximately three months.
Seedlings : Take out the seeds one by one from the bag and take care not breaking the germ (if there is one) and not turning them over on themselves. Bury lightly, less than a centimeter from the surface of the soil.
