How to Plant Cosmos
A comprehensive introduction to how to plant cosmos and the planting methods and management of cosmos flowers, which will surely be helpful to you. Let's learn about it together!
The scientific name of cosmos is "Cosmos bipinnatus," originally distributed in the Mexico region of the Americas. It is widely cultivated in Yunnan, Sichuan, and other areas in China. Cosmos generally grows on field 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 it to bloom in the summer, cosmos is usually planted between February and March every year during early spring, when the temperature and light are very suitable for cosmos growth. If planting outdoors, the planting time should be in April every year. For autumn blooming, the planting time is from 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. Mix cosmos seeds with sandy soil, sprinkle them on the seedbed, and cover 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, you can transplant them into pots and pinch the tips to promote flowering. Cosmos has large flowers, so multiple pinching is required during growth to encourage branching and flowering, and to prevent dwarfing of the plant. During maintenance, the plant should be provided with ample sunlight and water, but the watering amount should be controlled to avoid waterlogging and root rot. No additional fertilizing is needed during the growing period, as this can easily cause excessive growth of branches and leaves, affecting flowering.
The above is a complete introduction to how to plant cosmos and the planting methods and management of cosmos. I hope it can be helpful to you. Don't forget to check out more experience and common knowledge!
