Sowing requirement: keep the seeds in cool place, chilling hours is important but each species sowing season in hardiness zone 3-10 in spring, and in hardiness zone 10b-11 need to sow in the mid-winter, seeds to germinate better in full sun, soil need to be moist and don’t let it dry, consider also that each species require different condition, better to sow in potting mix or other kind of mix soil
Saving seeds and care until sowing: Cool and dry location, better in refrigerator
Sowing season: Spring to summer and rarely in autumn, optimal planting season for annual plant hardiness zone 3-10a in spring, hardiness zone 10b-11 in the end of the winter to early spring, optimal for perennial – hardiness zone 3-8 in spring, hardiness zone 6-10 summer, hardiness zone 10-11 autumn.
Planting spacing: 20*30cm, (8*12inches)
Depth of Sowing: 0.5cm (0.25inches)
Conditions for seeds germinate: Sunny location and moist soil
Watering requires for Seeds: Average amount of water / Big amount of water
Germination time: 1-4 weeks
Condition of seedling: Water regularly, better sunny location and keep soil moist
Do the seeds require burying? Yes, the seeds need cold stratification
