Notes
Seed counts are provided as a guide, not a guarantee. They vary from cultivar to cultivar. Planting rates will vary if intensive methods such as beds are used.
Minimum soil temperatures are the lowest that will permit any germination. Expect slow spotty germination if you plant below or above the ideal range. For a good stand and quickest emergence plant as close to the middle of the ideal range as possible. If you have specific cultural questions, consult more detailed resources or get in touch with us.
A few seeds with unusually thick or hard coatings may benefit from scarification just before sowing. This is accomplished by nicking them with a knife, a pinpoint or lightly scratching them with sandpaper.
Some seeds need to be stratified before sowing. This tricks the seed into thinking it has gone through winter followed by the gradual warm-up of spring. It is accomplished by first moistening and then chilling the seed for a specified period of time.
