Planting time of coriander
It is most suitable to plant coriander in April-May in spring and July-August in summer, because there is enough rain and sunshine in April-May, and it can grow faster after planting, while planting coriander in August-September has better benefits.
Planting time of southern coriander: it is warmer in the south. Generally, it is better to plant coriander in the autumn of10-1,and harvest it in the spring of the following year. Let the seeds germinate before sowing to promote germination after planting.
Planting time of northern coriander: Coriander is suitable for planting in late August in northern summer. Be careful not to plant it too late. If you sow it too late, the plant will grow too small, and there will be less nutrients in the plant, which will easily freeze to death in winter.
Coriander planting method
Before planting coriander, it is best to soak the seeds in warm water at 40 degrees for about 6 hours. After soaking, scatter the seeds in the soil and cover them with a thin layer of soil.
After the coriander seeds germinate, they can be placed in the sun and watered once in the morning and evening. After about a month, you can grow seedlings. If you see some seeds have not germinated, sow them again.
Key points of coriander planting management
After the emergence of coriander, it is necessary to water it in time to maintain the permeability of the soil, and it is also necessary to intertillage and weed regularly. When weeds appear in the fields, they need to be removed manually.
In addition, coriander should not be watered too much in seedling stage, and it should be watered once every 3-4 days, but it should be watered frequently in growth period to keep the soil moist, and quick-acting fertilizer should be the main fertilizer in growth period.
Diseases and pests may occur during the growth of coriander, and the main diseases and pests are leaf spot and aphid. Once the leaf spot is found, it can be controlled by spraying chlorothalonil and carbendazim solution in time. If aphids appear, they can be controlled by spraying avermectin and imidacloprid.
