Buy coriander seeds in bags or containers, roll them with a rolling pin or other tools, and the hard shell of coriander seeds will crack, which solves the phenomenon that coriander seeds are hard and difficult to germinate. After rolling, not only the germination rate will increase, but also the number of seedlings will increase.
After the seeds of coriander are spread out, the rest of the planting method is very simple. Prepare a vegetable pot, which is not necessary and can be of any size. Generally choose a rectangular vegetable basin, which can be varied. Spread a layer of soil on the bottom of the flowerpot first, and don't use the soil. Nutrient soil, garden soil or old soil left over from flower cultivation can be used. After filling a layer of subsoil, sprinkling a layer of organic fertilizer as base fertilizer can provide nutrients for subsequent growth.
After the organic fertilizer is sprinkled, continue to cover it until the container is almost 8 minutes full. Sprinkle the prepared rapeseed on it, sprinkle a layer on the surface, then continue to cover about 1cm, and water it once with a shower.
Matters needing attention in planting coriander
In the process of planting coriander, the seeds should be put in clean water 1~2 days, fished out and put in sandy soil to facilitate germination, and organic soil with strong water retention and good structure should be prepared. After planting, nitrogen fertilizer can be applied every two weeks at seedling stage, and the surrounding environment is controlled at 17℃ ~ 20℃.
During the growth of vegetables, some grass often grows around the pot soil. It is best to carry out intertillage weeding treatment when it grows rapidly to reduce nutrient consumption. Water too much at the seedling stage, otherwise some diseases will be found, and the seedlings should be kept moist when the height is 10 cm.
After sowing, it is necessary to shade in time to ensure that the soil is continuously moist, otherwise the surface will dry and crack carelessly, which will also affect the emergence of coriander. If there is no sunshade net at home, you can cut some tall thatch on the ridge and cover it on the seedbed.
