|Germination||Seeds have an internal dormancy that can be overcome by a moist, chilling period. This treatment is called stratification. Here are the steps to stratify the seeds:|
1. Soak the seeds in water overnight
2. Place the seeds in a moist material such as milled sphagnum peat, sterile soil or vermiculite . Fully drain away all of the water and place the seeds in a zip-lock bag.
3. Refrigerate the seeds for 2-3 months at 33 to 41 degrees Fahrenheit (+2 – +4C).
4. After the seeds are stratified, surface sow in a container filled with a moist, well-drained germination medium. Cover with glass or plastic and keep the container moist, but not soggy. Keep in room temperature.
5. Requires light for germination
As soon as the seeds germinate, place them under bright lights or move them to a greenhouse or cold frame.
You can sow seeds outdoors in well prepared beds in October or before the winter. Nature will do the job and will germinate in spring.
When large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame for their first winter.
