Coriander growing method and sowing time, at what temperature does it stop growing?

Friends who love making dumplings all know coriander, also known as cilantro, culantro, Chinese mosla, denseflower mosla, and so on. It was first recorded in 119 BC during the Western Han dynasty. It originated in Central Asia and southern Europe, or the Near East and the Mediterranean region. The tender stems and fresh leaves of coriander both have an aroma that stimulates the appetite, and it is one of the commonly used garnishes in cooking.

Coriander is an annual herbaceous plant of the genus Coriandrum in the Apiaceae family. It can be planted anywhere, and in the flower market it is most commonly seen in spring and autumn, mainly kept as potted plants or grown from seed. In terms of care, coriander by nature prefers a cool climate; it does not tolerate heat but tolerates cold. Its optimum growing temperature is 17 to 20 degrees Celsius. If the overall environment is above 20 degrees Celsius, it will begin to grow slowly, and in the heat of summer at 30 degrees Celsius it will enter dormancy and stop growing. Therefore, after buying it, it is recommended to place it on a shaded balcony to grow. As for soil, ordinary garden soil can grow it well; just follow the principle of loose soil with strong fertilizer and water retention. Afterwards, watering according to "water when dry, dry out between waterings" is enough to grow it well.

If what you bought at the flower market was seeds, the preferred sowing times are autumn and spring. In spring, sow from March to April. At this time the temperature gradually rises, which is good for seed germination and seedling growth. In autumn, from August to October, the climate is relatively cool and the light is sufficient; this is the growing environment coriander likes, and sowing at this time is also good for coriander's growth and development, with relatively fewer pests and diseases.

So, what should you pay attention to when sowing? Before sowing, you can first break open the outer skin of the coriander seeds. When sowing, there are two methods: direct sowing of dry seeds, or sowing after sprouting. In the former, bury the dry seeds in about 1 cm of soil, and water promptly after sowing to maintain temperature and humidity. If you choose to sow after sprouting, first soak the seeds with the outer skin broken open in water for 24 hours, then wrap them in a damp cloth and place them in a 20 degrees Celsius environment to sprout. Wait about 3 to 4 days before sowing. Once the seedlings have grown 3 to 4 leaves, they can be transplanted into pots for care, with a seedling spacing of 5 to 6 cm per clump.
