What are the cultivation methods of cosmos?
Article Abstract: This article provides knowledge about the cultivation methods of cosmos and the precautions for growing cosmos in the field of green plants and flowers. Detailed introduction is as follows:
The scientific name of cosmos is "Cosmos bipinnatus", which is originally distributed in the Mexico region of the Americas and is widely cultivated in Yunnan, Sichuan and other places in China. Cosmos usually grows on ridges or溪边, and in addition to its ornamental value, it also has the medicinal value of clearing heat and detoxifying. Next, let's get a detailed understanding of the planting methods of cosmos from aspects such as planting time, soil conditions, and plant maintenance.
1. Planting Time
If you want to bloom in summer, the planting time of cosmos is generally in February to March of early spring every year, 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 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 is suitable for growing in fertile, loose soil that contains organic matter. Some decomposed organic fertilizer can be applied to the soil before sowing 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. Control the temperature to maintain at about 18 degrees Celsius 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, pinched, which can promote flowering. Cosmos has large flowers, so multiple pinching is required during the growing process to promote branching and flowering, and also to avoid plant dwarfing. During maintenance, the plants should be provided with sufficient light and water, but the amount of watering should be controlled to avoid waterlogging and root rot. No topdressing is needed during the growing period, otherwise it can easily cause the stems and leaves to grow excessively, affecting flowering.
