How to Plant Cosmos Seeds
In detail, for netizens who are interested, the explanation of how to plant cosmos seeds and the planting methods and timing of cosmos flowers, the following editor will provide you with detailed answers.
The scientific name of cosmos is "Cosmos bipinnatus," originally distributed in the Mexico region of America. In China, it is widely cultivated in areas such as Yunnan and Sichuan. Cosmos generally grows in field ridges or along streams, and in addition to 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 it to bloom in summer, the planting time for cosmos is usually February to March every year during early spring, when 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 it to bloom in autumn, the planting time is 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, some decomposed organic fertilizer can be applied 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 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 grown 4-5 true leaves, they can be transplanted to pots and pinched to promote blooming. Cosmos flowers are large, so multiple pinching is required during growth to encourage branching and flowering, and to prevent plant dwarfing. During maintenance, ensure the plants get sufficient light and water, but be careful to control the watering amount 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.
