Stratification: Moist stratification for 90 days, at 3° C (37° F) to 5° C (41° F); some seeds may only germinate the second year after a second stratification period.
- Place seeds in sandwich bag(s), with a bit of damp sand or vermiculite to keep moist.
- Place the bag(s) with seeds in refrigerator for about 90 days.
- After the required time take the seeds out of the refrigerator and sow the seeds in pots 1/2 inch deep and cover lightly. Water gently so as not to wash away the seeds. Keep soil moist but not wet. Note, seeds have a deep dormancy and can take two years to germinate, which may require a repeat of the stratification period. So don’t give up.
