They are then placed in fine mesh bags, layered in peat in a covered container, and refrigerated at 1 to 3 °C for 100 days. 2) Seeds are soaked in a 1% hydrogen peroxide solution for 24 hours, rinsed, and placed in water for an additional 48 hours. They are then placed in a sealed container and subjected to warm stratification at 10 °C for 10 days, followed by cold stratification at 1 to 3 °C for 90 days. Weekly checks for mold are recommended during stratification.
