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 THREE MONTHS for seed treatment;
2. subject them to a thermal scarification AND a cold stratification before sowing (follow the steps below in order).

Thermal Scarification : Soak the pyrenes in hot tap water (around 60 ° C) and let the water cool normally for 24 hours. Following this process, several seeds should have swelled from their original size. Repeat this step for the seeds that have not changed in size and therefore have not been scarified properly.
Stratification (cold) : Place the pyrenes in a bag (Ziploc Slider type) containing slightly premoistened peat moss. Seeds should be surrounded by the latter. Close the bag and place it in cool storage (between 1°C and 5°C) for approximately three months.
Seedlings : Remove the content from the bag and sow the seeds by broadcasting the mix on the growth medium. Bury lightly, less than five millimeters from the soil surface.
