Cosmos is not cold-resistant and has high temperature requirements, generally needing to grow in an environment of 15-25 degrees Celsius. In spring, the temperatures in the north and south are relatively high, meeting the growth requirements of cosmos. Moreover, the precipitation increases in spring, and the soil has abundant fertility, which can shorten the germination time of cosmos. When sowing cosmos in autumn, measures to prevent frost damage are necessary. Frost periods are longer in autumn, so planters need to cover greenhouses.
