How to Plant Cosmos
Article Abstract: Let's explore the related aspects of how to plant cosmos and the cultivation and maintenance of cosmos in green plants.
The scientific name of cosmos is "Cosmos bipinnatus," originally distributed in the Mexico region of America, and it is widely cultivated in Yunnan, Sichuan, and other places in China. Cosmos usually grows on ridges or by streams, and in addition to its ornamental value, it also has medicinal properties for clearing heat and detoxifying. Next, 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 summer, the planting time is usually February to March in early spring every year, as the temperature and light 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 in July to August. The planting time of cosmos varies according to different needs.
2. Soil Conditions
Cosmos thrives 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. When sowing, mix cosmos seeds with sandy soil, sprinkle them on the seedbed, and cover them with a layer of fine 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 grown 4-5 true leaves, they can be transplanted into pots and pinched to promote blooming. Cosmos has large flowers, so multiple pinching is necessary during growth to promote branching and flowering, and also to avoid plant dwarfing. In the maintenance process, the plants should be provided with ample light and water, but be careful to control the amount of watering to avoid waterlogging and root rot. No top dressing is needed during the growing period, as it may easily cause the branches and leaves to grow excessively, affecting flowering.
