Each seed package carries a specific germination code along with the plant description. These codes indicate specific sowing instructions.
- A Seeds can be sown outdoors in early spring.
- B Seeds need a winter or cold period to germinate. Sow outdoors in fall or winter.
- C Seeds need light to germinate; sow on soil surface and leave uncovered.
- D Seeds need alternating cycles of warm-to-cold-to-warm to germinate. They can be sown either outdoors in spring or summer and will germinate the following year or in a flat in a warm place for 3 months, then moved to a refrigerator for 2 months, then moved outside in the early summer warmth.
- E Seeds can not be allowed to dry out. Sow immediately.
- F Seeds take two years to germinate. Sow outside in the fall or winter and look for germination in the second spring. A shady location prevents the flats from rapid drying and reduces weeding
- G Large seeds should be soaked overnight in water.
