The sowing time for cosmos is in spring, and they grow very fast, almost blooming right after the seeds are planted. By planting in February, you can see cosmos covering the mountains in May. After September, cosmos will gradually wither, but you can see new buds in a week or two. By October, there will be a new batch of flowers. If well cared for, cosmos can bloom continuously, with the previous flowers fading and the next ones blooming right after. This allows them to bloom from the flowering period all the way to winter. However, when it gets cold or after blooming once, the flowers may be smaller, but this does not affect their beauty.

Can cosmos seeds survive if sown in winter?
For cosmos grown in pots, after sprinkling the seeds on the surface, cover them with a layer of plastic wrap. This can prevent the seeds from being washed away when watering and also promote seed growth, giving them a better growing temperature. Seeds grown in this environment will sprout in less than a week. They should not be exposed to sunlight before sprouting, but once the seedlings appear, they must be moved to a sunny place to grow faster. Regular fertilization and watering are also needed, but the watering should not be too frequent, as it can cause root rot and lead to withering.
Before cosmos bloom, it is also necessary to tidy up and trim the flower cores a bit. This can encourage the growth of more flower buds. After the first batch of flowers fades, collect some seeds, place them in a dry cloth bag for storage, and make sure they do not get damp. Besides growing them yourself, you can also give some to friends. If you don't want to give away flowers, you can give seeds instead, as they are also easy to grow.
