-
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.
