How to Plant Cosmos Seeds
The editor is here to answer netizens' questions about how to plant cosmos seeds and the sowing methods and timing for cosmos, sharing knowledge about green plants and flowers. Next, let's proceed with the introduction.
1. Sowing Time
Sowing cosmos in spring is the best, as it can bloom in May of the same year after sowing, with the blooming period lasting until August. When autumn comes, cosmos can bloom again, with the blooming period lasting until frost. Therefore, the best sowing time is in spring. If sown in August, it will only bloom in October, and the ornamental value after blooming is not high.
2. Sowing Process
Prepare cosmos seeds in advance and then scatter the seeds one by one in the potting soil. After scattering the seeds, cover them with a thin layer of soil to prevent seed accumulation after watering. Next, water thoroughly and move the pot to a shady place, waiting patiently for the cosmos to germinate.
3. Post-Sowing Care
After sowing cosmos in the pot, it is necessary to control the temperature, with around 15 degrees Celsius being the best. This temperature is conducive to cosmos germination, and the seeds will germinate within a week if the temperature is appropriate. After germination, move the pot to a place with good lighting. However, avoid direct strong sunlight and choose diffused light instead, allowing cosmos to gradually adapt to sunlight. Then, water and fertilize appropriately, making sure not to over-fertilize as it can damage the roots. In the later stage, pinching is required to ensure more blooms during the flowering period.
