coriander (coriander) can be cultivated in Sichuan all year round, especially in spring. Just choose the planting soil. Cultivation techniques: Coriander can be sown all year round, but spring is the most suitable. Coriander likes warm, fat and wet, so it should be planted in loam with ventilation and light transmission, convenient irrigation and drainage, loose and fertile soil. Before soil preparation, farm manure was spread, and after deep ploughing, the border was made, with a width of 1m. Because the seeds are small, the seeds can be mixed with fine sand first when sowing.
