How to plant cosmos seeds
A comprehensive guide on how to plant cosmos seeds and detailed knowledge about cosmos cultivation techniques in the field of flowers. Let's take a look together.
For the best sowing time and maintenance of cosmos, enthusiasts who enjoy raising flowers must master these aspects.
Also known as gesanghua, cosmos have unique and beautiful flower shapes, particularly valuable for观赏. The best planting time for cosmos is in spring and autumn because the weather is neither too hot nor too cold, which is suitable for the growth of many flowers. Cosmos planted in spring can bloom in May, with a flowering period of up to three months. Don't mind the short blooming period; although it only offers three months of viewing time, cosmos will bloom again after the flowers fade. Cosmos are not one-time flowering plants and will continue to bloom until the cold weather of the beginning of winter. So, when is the best time to sow cosmos seeds?
The sowing time for cosmos is in spring, and they grow very quickly, almost blooming after March. If sown in February, you can see fields of cosmos in May. Cosmos planted after September will gradually wither, but new flower buds will appear in a week or two. By October, there will be a new batch of flowers. With good care, they will bloom continuously, with the flowers in front fading and new ones blooming right after, allowing the flowering period to last until winter. However, the flowers will be smaller when it's cold or after blooming once, but this does not affect their beauty.

Now is the most suitable time for planting cosmos. However, the weather has been quite overcast recently. If it's cloudy, first place the seeds you bought in a dry cloth bag and put it in a dry place to prevent them from molding or germinating. Then, take out all the flower pots at home for planting. Simply sprinkle the seeds on the soil surface; there's no need to dig holes to bury them. Planting cosmos in the ground is even simpler; just loosen the soil where you want to plant cosmos and sprinkle the seeds on the surface.

When growing cosmos in pots, after sprinkling the seeds on the surface, cover them with a layer of plastic wrap to prevent the seeds from being washed away during watering. This also promotes seed growth and provides a better growth temperature. Seeds grown in such an environment will sprout in less than a week. Before sprouting, they should not be exposed to sunlight, but once the seedlings appear, they must be moved to a sunny area to promote faster growth. It's also necessary to fertilize and water regularly, but not too frequently, as excessive watering can cause root rot and lead to withering.
Before cosmos bloom, it's necessary to tidy up and trim the flower cores appropriately. This encourages the growth of more flower buds. After the first batch of flowers fade, collect some seeds and store them in a dry cloth bag to prevent them from getting damp. Besides raising 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 relatively easy to grow.
