In order to make coriander germinate as soon as possible, it is suggested to accelerate germination before sowing. Accelerating germination means soaking seeds in water for a period of time, and then sowing after the seeds are exposed. When sowing, you can also choose rotten soil and then pour a small amount of water. This can greatly shorten the growth cycle of coriander, thus shortening the germination time of coriander.
Coriander is afraid of heat, so it likes to grow in a cold environment. The main cultivation period is autumn, with short sunshine and low temperature, which is suitable for the growth of coriander. Keep the temperature at about 13℃- 15℃, strengthen fertilizer and water management and disease prevention measures, and germinate in 6-7 days.
After planting coriander, always observe the ambient temperature, strengthen air circulation, and then water it once every two days, a small amount at a time, as long as the soil surface is wet. The ambient temperature should be controlled between 15℃-20℃, and then a small amount of urea can be added.
