How to plant cosmos seeds
The website introduces how to plant cosmos seeds and related introductions about cosmos cultivation methods and precautions for green plants and flowers. Let's understand together.
For cosmos, the best sowing time and maintenance aspects, cosmos enthusiasts must master.
Also known as Gesanghua, cosmos has unique and beautiful flower shapes, especially ornamental value. The best planting time for cosmos is in spring and autumn because the weather is warm and cool, which is the growth stage for many flowers, making it very suitable. Cosmos planted in spring can bloom in May, and the flowering period can last for three months. Don't mind the short flowering period; although it only has a three-month viewing period, after the flowers fade, new flowers will bloom again after a short while. Cosmos is not a plant that blooms only once. It will stop blooming only when the weather gets cold after the beginning of winter. So, when is the sowing time for cosmos?
The sowing time for cosmos is in spring, and it grows very fast, almost blooming around the same time as the planting date. By播种 in February, you can see cosmos everywhere in May. After September, cosmos will gradually wither, but you can see new flower buds after a few weeks. By October, it's a new batch of flowers. If well cultivated, the flowers will bloom continuously, with the front ones fading and the back ones blooming. This allows 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 to plant cosmos, but the weather has been quite overcast recently. If it's a cloudy day, first put the seeds you bought into a dry cloth bag and place them in a dry place to prevent them from mildewing or germinating. Then take out all the flower pots of different sizes at home. When planting, 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 cosmos is grown 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 when watering. This also promotes seed growth and provides a better growing temperature. Seeds grown in this environment will sprout in less than a week. They should not be exposed to sunlight before germination, but once the seedlings are visible, they must be moved to a sunny place to grow faster. Regular fertilizing 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 flowers, it's also necessary to tidy up and trim the flower cores appropriately to encourage more flower buds. After the first batch of flowers fades, you can collect some seeds to plant, putting them in a dry cloth bag for storage and making 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 relatively easy to grow.
