How to Plant Cosmos
Today's experience sharing: Introduction on how to plant cosmos and the planting methods and timing of cosmos in the field of green plants and flowers. Next, the editor of this site will introduce cosmos planting to netizens.
The scientific name of cosmos is "Cosmos bipinnatus," originally distributed in the Mexico region of America. It is widely cultivated in Yunnan, Sichuan, and other areas in China. Cosmos usually grows on ridges or by streams, and in addition to its ornamental value, it also has the medicinal value of clearing heat and detoxifying. Let's take a detailed look at the cosmos planting methods from aspects such as planting time, soil conditions, and plant maintenance.
1. Planting Time
If you want it to bloom in summer, the planting time for cosmos is generally February to March in early spring every year, as the temperature and light are very suitable for cosmos growth. If planting outdoors, the planting time should be in April every year. If you want it to bloom in autumn, the planting time is in July to August. The planting time for cosmos varies according to different needs.
2. Soil Conditions
Cosmos is suitable for growing in fertile, loose soil with 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 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 4-5 true leaves, they can be transplanted into pots and pinched to promote flowering. Cosmos flowers are large, so multiple pinching is necessary during growth to promote branching and flowering, and to prevent 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. There is no need to apply fertilizer during the growing period, as it can easily cause the branches and leaves to grow excessively, affecting flowering.
The above is a specific introduction on how to plant cosmos and the methods and timing of cosmos planting, hoping to bring some floral knowledge to green plant enthusiasts.
