Secondly, the seeds of coriander have a hard shell, which can be rubbed by hand before sowing until most of the seed shells crack. We only sow the seeds directly, and the seedlings will emerge about a week after sowing. You can also soak the seeds for 12 hours before sowing. In fact, soaking seeds to accelerate germination is the behavior of vegetable producers. If we plant a small amount ourselves, we can sow dry seeds.
Let's talk about the planting steps of coriander in detail:
1. Soil preparation: wet the ground first, then sprinkle farm manure and compost, then turn over the ground and rake it flat to make the soil soft and rake it flat.
2. Seeding ditch, 2 cm deep and 5- 10 cm apart. You can also cover the soil after sowing at will.
3. The soil must be kept moist after sowing, which is the key to seed germination. Our practice is to directly cover the plastic film, which can keep moisture and keep warm if the temperature is low. Look at it once a day and uncover the plastic film in time after germination.
4. When the coriander grows to two leaves and one heart, it should be sown in time, and then the soil should be kept moist, and it can be irrigated with small water. There are few pests and diseases in coriander, so spraying is basically not needed.
