Do you know about these? The relevant experience of seeding Cosmos properly and understanding the cultivation steps of Cosmos flowers, let's follow the editor to take a look together!
For Cosmos enthusiasts, it is essential to master the best seeding time and maintenance aspects.
Also known as Gesanghua, Cosmos has a unique and beautiful flower shape, especially ornamental value. The best planting time for Cosmos is in spring and autumn because the weather is warm and cool, which is the growing stage for many flowers, so it's perfect. Generally, 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 there are only three months of ornamental period, after the flowers fade, a second bloom will appear after a short time. Cosmos is not a one-time flowering plant and will stop blooming only when it gets cold at the beginning of winter. So, when is the best time to sow Cosmos?
The sowing time for Cosmos is in spring, and it grows very fast, almost blooming at the same time as it is planted. By February, you can see fields of Cosmos in May. After September, Cosmos will start to wither, but new flower buds can be seen in a week or two. By October, there will be a new batch of flowers. If well cared for, the flowers will bloom continuously, with the previous ones fading and the new ones blooming, lasting from the flowering period to winter. However, when the weather gets cold or after blooming once, the flowers will be smaller, but this does not affect their beauty.
Seeding method for Cosmos
Now is the most suitable time to plant Cosmos, but the weather has been quite overcast recently. If it's cloudy, first put the seeds you bought into a dry cloth bag and place it in a dry place to prevent mold or germination. Then, take out all the flowerpots of different sizes at home. When planting, just 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.
How to seed Cosmos properly
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 can also promote seed growth and provide a better growing temperature. Seeds grown in this environment will sprout in less than a week. Before germination, they should not be exposed to sunlight, but once the seedlings appear, they must be moved to a sunny place to speed up their growth. It's also important to fertilize and water regularly, but not too frequently, as this can cause root rot and lead to withering.
Before Cosmos blooms, it's necessary to tidy up and trim the flower cores appropriately, which can promote the growth of more flower buds. After the first bloom, you can collect some seeds and store them in a dry cloth bag to prevent moisture. Besides growing them yourself, you can also give some to friends, or if you don't want to give away flowers, you can give seeds instead, as they are relatively easy to grow.
