Seeds can be sown without any pretreatment, but some short cold moist stratification will make the germination process faster and rate higher. Make sowing from January to June.
1. Soak the seeds in warm water for 24 hours. Fully drain away all of the water, mix with moist vermiculite and place the seeds in a zip-lock freezer bag . Place the seeds in the fridge for 3-4 weeks (recommended but not required).
2. After this period sow seeds in into containers filled with a good quality and clean (not used before or sterilized) potting compost in pots, trays or plug trays. Firm the compost gently and sow the seeds on the surface. If you are sowing in plug trays, sow 2 or 3 seeds per cell.
Cover the seeds with a couple of millimeters of vermiculite or failing that a fine layer of sieved compost. Follow with a gentle watering and keep them at room temperature. Germination will begin within a 10-14 days of sowing.
