How to PlantCosmos Flowers

A guide to planting cosmos flowers and cultivation techniques, this green plant flower introduction will surely be helpful to you. Let's learn about it together!

Cosmos, scientifically known as "Cosmos bipinnatus", is originally distributed in the Mexico region of the Americas and is extensively planted in Yunnan, Sichuan and other areas in China. Cosmos usually grows on ridges or by streams, possessing not only ornamental value but also the medicinal value of clearing heat and detoxifying. Next, let's dive into the planting methods of cosmos from aspects such as planting time, soil conditions, and plant maintenance.

1. Planting Time

For summer blooming, cosmos is usually planted between February and March every year when the temperature and sunlight are suitable for cosmos growth. For outdoor planting, 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, some decomposed organic fertilizer can be added 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 thin layer of soil about 1 cm thick. Maintain the temperature at around 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 into pots and pinched to promote blooming. Cosmos has large flower shapes, so it needs to be pinched several times during growth to promote branching and flowering, as well as to prevent the plant from becoming dwarfed. During maintenance, the plants should be provided with ample sunlight and water, but be careful to control the amount of watering to avoid waterlogging and root rot. There is no need to fertilize during the growing period, as this can easily cause the stems and leaves to grow excessively, affecting flowering.
