How to Plant Cosmos
For most women, the knowledge about how to plant cosmos and the timing and methods of cosmos cultivation, the following is a detailed introduction.
The scientific name of cosmos is "Cosmos bipinnatus," originally distributed in the Mexico region of the Americas, and it is extensively cultivated in Yunnan, Sichuan, and other areas in China. Cosmos usually grows on ridges or near streams, and besides its ornamental value, it also has medicinal properties for clearing heat and detoxifying. Let's delve into the planting methods of cosmos from aspects such as planting time, soil conditions, and plant maintenance.
1. Planting Time
If you want cosmos to bloom in the summer, the planting time is generally in early spring, from February to March each year, when the temperature and sunlight are very suitable for the growth of cosmos. If it is planted outdoors, the planting time should be in April every year. If you need cosmos to bloom in autumn, the planting time is from July to August. The planting time of cosmos varies according to different needs.
2. Soil Conditions
Cosmos is suitable for growing in fertile, loose soil that contains organic matter. Before sowing, you can add some decomposed organic fertilizer to the soil to increase soil fertility and promote plant growth. Mix cosmos seeds with sandy soil, sprinkle them on the seedbed, and cover them with a thin layer of soil about 1 centimeter thick. Maintain the temperature at around 18°C and keep the soil slightly moist.
3. Plant Maintenance
About 20-30 days after sowing, cosmos will take root and sprout. When the seedlings have 4-5 true leaves, they can be transplanted to pots and pinched to promote flowering. Cosmos has large flower shapes, so multiple pinching is necessary during growth to promote branching and flowering, and to prevent dwarfing of the plants. During maintenance, the plants should be provided with ample sunlight and water, but the watering amount should be controlled to avoid waterlogging and root rot. No additional fertilization is needed during the growing period, as this can easily cause excessive growth of branches and leaves, affecting flowering.
