If they have not germinated after 4 weeks then a cooling period is required. Cover them with plastic and place in a fridge for 4 weeks. Be sure they stay moist. After the cold-moist stratification period they are then brought back to room temperature. for them to germinate. Germination can be 30-60 days after the warming period, though some can take longer.
