The right time
So-called coolflowers, or hardy annuals such as lady's mantle, annual delphiniums, wild carrots, scabious, or coneflowers, which require a cold stimulus, are sown in August or September of the previous year, or can be sown in small pots as early as the end of February. The young plants can then be planted in the garden bed at the end of March or beginning of April, or they can also be sown directly. Some varieties, such as lady's mantle or poppies, are best sown directly in the garden bed, as they don't tolerate transplanting very well.
As the saying goes, anticipation is the greatest joy. This also applies to sowing! With frost-sensitive summer flowers, it's important not to sow too early, as the plants need at least twelve hours of light immediately after germination. And unfortunately, depending on the region, this isn't until around March 20th. Before then, cultivation would only succeed with artificial light. Therefore, you shouldn't start sowing the remaining annual summer flowers until mid-March. These, too, are sown indoors first. Only after the Ice Saints in mid-May, when the danger of frost has passed, can they be planted in frost-free ground.
