Propagation of Cosmos Seeds
Cosmos are grown from large seeds, making them easy to sow. They germinate quickly and from then on - never stop. Whilst cosmos seeds can be directly seeded into your garden, an early, indoor start, translates into an earlier, so we recommend starting indoors. Sow seeds on a good quality compost straight into pots and cover lightly with compost or vermiculite. Germination of seeds is usually around 5 - 7 days. Do not place the seedlings outside until after the last frost date your area as cosmos plants are susceptible to frost.
