How to grow coriander seed
The best planting time for coriander seeds is generally in the spring and autumn season, and can be sown all year round in the south. When the temperature is too high, the seeds need to be soaked for 24 hours and then germinated at 20: 25 ℃. Gently crack the coriander seeds and soak them in 40 degrees warm water for 6 hours. Pour the prepared soil into a container and pour water thoroughly. Sprinkle the seeds in the soil and cover with a layer of about 1 cm of thin soil to water sooner or later. Young seedlings can grow in about a month.
The best planting period from September to October, spring sowing is also possible (it can be planted all the year round in the south)
When sowing seeds at high temperature in summer, it is necessary to sprout at 20-25 degrees after soaking seeds, otherwise it is difficult to emerge seedlings.
The first step: gently crack the coriander seed (to sprout)
Step 2: soak in warm water at about 40 degrees for 6 hours (warm water to sprout and wake them up) (4 hours at room temperature in summer and autumn)
Step 3: prepare the planting soil and water it thoroughly first
Step 4: spread the seeds and place them on the soil, gently cover the seeds with a thin layer of soil (0.5 cm thick) (random spacing).
Step 5: when the border surface is dry, suppress a time to preserve soil moisture. If the weather is dry and the soil moisture is poor, irrigate a little water again. If it rains after sowing, loosen the soil in time and pour a little water to facilitate the emergence of seedlings. The amount of seed used per mu is 2m / m and 3kg / mu.
In seven or eight days, sprouts and true leaves grow, and you can eat them in about forty days.

The seeds were soaked for about 4 hours, washed 2-3 times to drain the seeds, and germinated under the condition of 28-30 ℃. Maintain high temperature after sowing to promote seedling emergence, usually about 3 days after sowing. The seedlings can be transplanted when they grow to 2-3 true leaves. When the seedlings grow to 4-5 leaves, pull out the weak plants.
